The completed sequence would then be: 2, 4, 7, 9, 16, 19, 29.
To complete the given number sequence, let's analyze the pattern and identify the missing terms.
Looking at the given sequence 2, 4, 7, __, 16, __, 29, __, we can observe the following pattern:
The difference between consecutive terms in the sequence is increasing by 1. In other words, the sequence is formed by adding 2 to the previous term, then adding 3, then adding 4, and so on.
Using this pattern, we can determine the missing terms as follows:
To obtain the third term, we add 2 to the second term:
7 + 2 = 9
To find the fifth term, we add 3 to the fourth term:
16 + 3 = 19
To determine the seventh term, we add 4 to the sixth term:
__ + 4 = 23
Therefore, the missing terms in the sequence are 9, 19, and 23.
By identifying the pattern of increasing differences, we can extend the sequence and fill in the missing terms accordingly.

What can you say about the y-values of the two functions f (x) = 3 - 3
and g(x) = 7x² - 3?
☐A. The minimum y-value of f(x) is
B. The minimum y-value of g(x) is -3.
C. g(x) has the smallest possible y-value.
D. f(x) has the smallest possible y-value.
SUBMIT
Answer: B. The minimum y-value of g(x) is -3.
Step-by-step explanation:
Based on the given functions:
f(x) = 3 - 3
g(x) = 7x² - 3
The y-value of f(x) is constant at -3, regardless of the value of x. Therefore, f(x) does not have a minimum y-value, and option A is incorrect.
The y-value of g(x) is determined by the quadratic term 7x². Since the coefficient of x² is positive (7), the parabola opens upwards, indicating that g(x) has a minimum y-value. To find the minimum value of g(x), we can look at the vertex of the parabola, which occurs when x = -b/2a in the quadratic equation ax² + bx + c. In this case, a = 7 and b = 0, so the vertex is at x = -0/2(7) = 0. Substituting x = 0 into g(x), we find: g(0) = 7(0)² - 3 = -3 Therefore, the minimum y-value of g(x) is -3, and option B is correct.
Option C, stating that g(x) has the smallest possible y-value, is incorrect because the y-value of g(x) can be larger than -3 depending on the value of x.
Option D, stating that f(x) has the smallest possible y-value, is incorrect because f(x) does not have a minimum y-value as it is constant at -3.
Therefore, the correct answer is B. The minimum y-value of g(x) is -3.

A rock is thrown upward with a velocity of 11
meters per second from the top of a 43
meter high cliff, and it misses the cliff on the way back down. When will the rock be 10
meters from ground level? Round your answer to two decimal places.
Step-by-step explanation:
We can use the equation h(t) = -4.9t^2 + vt + h0, where h0 is the initial height of the rock, v is the initial velocity and t is time in seconds, to solve the problem.
h0 = 43 meters (the top of the cliff)
v = 11 meters per second (upwards direction)
To find the time when the rock is 10 meters from ground level, we set h(t) = 10 meters and solve for t:
10 = -4.9t^2 + 11t + 43
0 = -4.9t^2 + 11t + 33
Solving this quadratic equation, we get t = 4.04 seconds or t = 1.37 seconds.
Since the rock is thrown upwards, it will be 10 meters from ground level twice - once on the way up and once on the way down. We can discard the negative time answer as that would correspond to when the rock is thrown from the ground.
Therefore, the rock will be 10 meters from ground level after 4.04 seconds (on the way down).
An English teacher counted the number of misspelled words in a 1000-word essay he assigned to his students. From a group of 49 students, the mean number of misspelled words was 9.1. The distribution of the student population is normal with a variance of 12.25. What is a confidence interval for the mean number of misspelled words in the student population, considering a confidence level of 99.7%? (Use 3 for the Z value in the formula below)
Answer:
C. [7.6, 10.6]
Step-by-step explanation:
To calculate the confidence interval for the mean number of misspelled words in the student population, we can use the confidence interval formula:
[tex]\boxed{CI=\overline{x}\pm z\left(\dfrac{s}{\sqrt{n}}\right)}[/tex]
where:
[tex]\overline{x}[/tex] is the sample mean.z is the confidence level value.s is the sample standard deviation.n is the sample size.Given values:
[tex]\text{Mean}\;\overline{x} = 9.1[/tex][tex]\text{Variance}\;s^2=12.25[/tex][tex]\text{Sample size}\;n=49[/tex]The standard deviation is the square root of the variance:
[tex]s=\sqrt{s^2}=\sqrt{12.25}=3.5[/tex]
The empirical rule states that approximately 99.7% of the data points will fall within three standard deviations of the mean.
Therefore, z-value for a 99.7% confidence level is z = 3.
Substituting these values into the formula, we get:
[tex]CI=9.1\pm 3\left(\dfrac{3.5}{\sqrt{49}}\right)[/tex]
[tex]CI=9.1\pm 3\left(\dfrac{3.5}{7}\right)[/tex]
[tex]CI=9.1\pm 3\left(0.5\right)[/tex]
[tex]CI=9.1\pm 1.5[/tex]
Therefore, the 99.7% confidence limits are:
[tex]CI=9.1-1.5=7.6[/tex]
[tex]CI=9.1+1.5=10.6[/tex]
Therefore, the confidence interval for the mean number of misspelled words in the student population is [7.6, 10.6].
triangle PQR was rotated and then dilated by a scale factor of 9 to create P”Q”R”. Which statement explains why triangle PQR is similar to triangle P”Q”R”?
Triangle PQR is similar to triangle P”Q”R” because the rotation and dilation transformations preserve the shape and angles of the original triangle.
The rotation simply changes the orientation of the triangle, but the angles and side lengths remain the same. The dilation scales all the side lengths by a factor of 9, which preserves the ratios of the side lengths and the angles of the original triangle.
Since similarity of two triangles is defined as the correspondence between the angles of one triangle to the angles of another triangle, and the ratio of the lengths of the corresponding sides is constant, PQR is similar to P”Q”R” because the angles of PQR and P”Q”R” are congruent, and the ratio of the lengths of the corresponding sides is the same. This means that PQR and P”Q”R” have the same shape and are therefore similar.

A student is applying to the University of Florida (UF) and Florida State (FSU).
There is a 40% chance of being accepted at FSU. If the student is accepted at FSU, the probability of being accepted at UF is 60%. If the student is not accepted at FSU there is an 90% chance of non-acceptance at UF.
What is the probability that a student is accepted at FSU or is accepted at UF?
Answer:
Hope this helps and have a nice day
Step-by-step explanation:
To find the probability that a student is accepted at FSU or accepted at UF, we can use the concept of conditional probability and the law of total probability.
Let's denote the events as follows:
A: Accepted at FSU
B: Accepted at UF
We need to find P(A or B), which can be calculated as the sum of the probabilities of each event minus the probability of their intersection:
P(A or B) = P(A) + P(B) - P(A and B)
Given the information provided, we can calculate the probabilities:
P(A) = 0.4 (40% chance of being accepted at FSU)
P(B|A) = 0.6 (60% chance of being accepted at UF if accepted at FSU)
P(B|A') = 0.9 (90% chance of non-acceptance at UF if not accepted at FSU)
P(A and B) = P(A) * P(B|A) = 0.4 * 0.6 = 0.24 (probability of being accepted at both FSU and UF)
Now we can substitute these values into the formula:
P(A or B) = P(A) + P(B) - P(A and B)
= 0.4 + (1 - 0.4) * P(B|A') - P(A and B)
= 0.4 + 0.6 * 0.9 - 0.24
= 0.4 + 0.54 - 0.24
= 0.7
Therefore, the probability that a student is accepted at FSU or accepted at UF is 0.7, or 70%.

A hawker bought boxes of tomatoes at R18 per box at the market. He sold all but 5 boxes which went bad, at R25 per box. If he made a profit of R155, how many boxes of tomatoes did he buy?
Answer:
Hope this helps and have a nice day
Step-by-step explanation:
Let's denote the total number of boxes the hawker bought as "x".
The cost of each box is R18, so the total cost of buying "x" boxes is 18x.
He sold all but 5 boxes, so he sold (x - 5) boxes at R25 per box. The revenue from selling these boxes is 25 * (x - 5).
The profit is calculated by subtracting the cost from the revenue, so we have:
Profit = Revenue - Cost
155 = 25 * (x - 5) - 18x
Simplifying the equation:
155 = 25x - 125 - 18x
155 + 125 = 25x - 18x
280 = 7x
Dividing both sides by 7:
x = 280 / 7
x = 40
Therefore, the hawker bought 40 boxes of tomatoes.
Evaluate leaving your answer in a standard form 0.0048*0.81 /0.027*0.04
Step-by-step explanation:
When we simplify the expression, we get:
0.0048 * 0.81 / 0.027 * 0.04 = (0.0048 / 0.027) * (0.81 / 0.04)
Using a calculator to evaluate the two fractions separately, we get:
0.0048 / 0.027 ≈ 0.1778
0.81 / 0.04 = 20.25
Substituting these values back into the original expression, we get:
(0.0048 / 0.027) * (0.81 / 0.04) ≈ 0.1778 * 20.25
Multiplying these two values together, we get:
0.1778 * 20.25 ≈ 3.59715
To express the answer in standard form, we need to write it as a number between 1 and 10 multiplied by a power of 10. We can do this by moving the decimal point three places to the left, since there are three digits to the right of the decimal point:
3.59715 ≈ 3.59715 × 10^(-3)
Therefore, the final answer in standard form is approximately 3.59715 × 10^(-3).

remaining sides of A THE. Give exact answers.
E
Answer:
Step-by-step explanation:
To determine the remaining sides of triangle THE given that sin(E) = 4 and TE = 4, we can use the sine ratio.
The sine ratio is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle.
In this case, sin(E) = 4/TE, which means the side opposite angle E is 4 and the hypotenuse TE is 4.
Using the Pythagorean theorem, we can find the length of the remaining side TH:
TH^2 = TE^2 - HE^2
TH^2 = 4^2 - 4^2
TH^2 = 16 - 16
TH^2 = 0
TH = 0
Therefore, the length of side TH is 0.

Step-by-step explanation:
This is an isosceles triangle which always has:
two legs that are congruent to each other (i.e., equal),and two angles that are congruent to each other.In this triangle, the legs CA and BA are congruent so CA = BA and the angles C and B are congruent to each other so angle C = angle B.
Thus, we can find x by setting CA and BA equal to each other:
(3x - 15 = x + 33) + 15
(3x = x + 48) - x
(2x = 48) / x
x = 24
Thus, x = 24
Since the length of BC is x and x = 24, BC is 24 units long.

If the commercial banking system actually lends out the maximum amount it is able to lend, the excess reserves will be reduced to zero. This is because there will be no excess reserves held by the commercial banking system after lending out $9 billion.
Given that the required reserve ratio is 30 percent and all figures are in billions, the following table shows the total reserves, excess reserves, and required reserves:
Required reserve ratio 30% Checkable deposits $140Billion Reserves required (30% of checkable deposits)$42Billion Reserves held $51Billion Excess reserves held $9Billion Loans outstanding $109Billion Total Securities $100Billion Total Property $10Billion Total Assets $260Billion Stock shares $130Billion Total liabilities $130Billion Net worth (total assets - total liabilities) $130Billion.
Therefore, the total reserves held is $51 billion, and the reserves required is 30% of $140 billion, which is $42 billion.
This implies that the excess reserves are $9 billion.The maximum amount the commercial banking system can lend out is $51 billion minus $42 billion, which is $9 billion.
