Answer:
6300 m³
Step-by-step explanation:
The volume of the pyramid is given by the formula ...
V = 1/3s²h
where s is the side length of the square base, and h is the height.
V = 1/3(30 m)²(21 m) = 6300 m³
The approximate volume of the pyramid is 6300 m³.

26. Find the Rate when given the Interest.
Interest: $480
Principal: $1600
Time: 6 years *
(1 Point)
5%
0.05%
20%
2.0%
Answers
Explanation: Use the formula I=prt
Since we do not have the rate, but we have the interest, we plug in everything and try to solve for r (the rate).
480=(1600)(r)(6). To get r alone, we divide out the 6 and 1600. This leaves us with our answer to be r = 0.05. Although this is not in a percentage and we would need it to be, so we would have to multiply it by 100. This gives our percentage to be 5%.
Zain bought ice cream and sherbet at the grocery store and is placing the containers in the freezer. The container of ice cream was sold in a 10” 14” 12” container, and the sherbet was sold in an 11” 18” 9” container. How much less space does the container of ice cream occupy than the container of sherbet?
Answers
Answer:
102 in^3.
Step-by-step explanation:
Volume of the ice cream container = 10*14*12 = 1680 in^3.
Volume of the sherbet container = 11*18^9 = 1782 in^3.
So the answer is 1782 - 1680
= 102 in^3.

Answers
Answer:
m[tex]\widehat{WXY}[/tex] is 224°
Step-by-step explanation:
From the figure, we have;
The angle subtended at the circumference, by the arc mWXY, C = 112°
The angle subtended at the center = m[tex]\widehat{WXY}[/tex]
By circle theory, we have;
The angle subtended at the center = 2 × The angle subtended at the circumference
∴ m[tex]\widehat{WXY}[/tex] = 2 × 112° = 224°
m[tex]\widehat{WXY}[/tex] = 224°.

Answer:
[tex]\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}[/tex]
Step-by-step explanation:
if [tex]\sec x = \frac{4}{3}[/tex], then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.
The other leg (specifically the opposite one) will be equal to [tex]\sqrt{16-9} = \sqrt{7}[/tex] by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = [tex]\frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}[/tex].
cot(x) is defined as adjacent over opposite, which is equal to [tex]\frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}[/tex]
That means that the first option, the leftmost one, is correct.

A parabola can be drawn given a focus of (4, -8) and a directrix of y=-6
. What can be said about the parabola?
Answers
Answer:
y = 1/4 (x-4)² - 7
Step-by-step explanation:
Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
√(x-4)²+(y- -8)² = √(y- -6)²
(x-4)² + (y+8)² = (y+6)²
(y+8)² - (y+6)² = (x-4)²
(y²+16y+64) - (y²+12y+36) = (x-4)²
y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
4y = (x-4)² - 28
y = 1/4 (x-4)² - 7
standard formula of parabola: y = a(x-h)² + k (h,k): vertex (4,-7)
The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
Now,
Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6
Hence, We can formulate;
⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²
⇒ (x-4)² + (y+8)² = (y+6)²
⇒ (y+8)² - (y+6)² = (x-4)²
⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²
⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²
⇒ 4y = (x-4)² - 28
⇒ y = 1/4 (x-4)² - 7
Thus, The value of equation of parabola is,
⇒ y = 1/4 (x-4)² - 7

the area is ___ square units
Answers
Answer:
392 square units
Step-by-step explanation:
We can make 2 right trapezoids out of this shape.
The area of a trapezoid would be 1/2×(b1+b2)×h or (b1+b2)×h ÷ 2.
If we do 1 half it would be 1/2×(14+14)×14 = 196
Now if we multiply by 2 (because we have 2 trapezoids) it would be 392.

Alan made $396 for 18 hours of work. At the same rate, how much would he make for 11 hours of work?
Answers
Answer:
Step-by-step explanation:
I think it is helpful to set this up as a proportion as it is the easiest way in my opinion.
1st step: 396/18 and x/11
This is the way you set up the proportion.
2nd Step: You would have to multiply 396 and 11 then divide the value by 18.
396x11 = 4,356
4,356/18 = 242
x=242 Dollars
Answer: 242 dollars
Therefore, Alan would make 242$ while working at the same rate for 11 hours.
Two ride-sharing companies, A and B, provide service for a certain city. A random sample of 52 trips made by Company A and a random sample of 52 trips made by Company B were selected, and the number of miles traveled for each trip was recorded. The difference between the sample means for the two companies
(A−B) was used to construct the 95 percent confidence interval (1.86,2.15).
Which of the following is a correct interpretation of the interval?
A. We are 95 percent confident that the difference in sample means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
B. We are 95 percent confident that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
C. The probability is 0.95 that the difference in sample means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
D. The probability is 0.95 that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
E. About 95 percent of the differences in miles traveled by the two companies are between 1.86 miles and 2.15 miles.
3. Two community service groups, J and K, each have less than 100 members. Members of both groups volunteer each month to participate in a community-wide recycling day. A study was conducted to investigate whether the mean number of days per year of participation was different for the two groups. A random sample of 45 members of group J and a random sample of 32 members of group K were selected. The number of recycling days each selected member participated in for the past 12 months was recorded, and the means for both groups were calculated. A two-sample t-test for a difference in means will be conducted. Which of the following conditions for inference have been met?
I. The data were collected using a random method.
II. Each sample size is less than 10 percent of the population size.
III. Eachsamplesizeislargeenoughtoassumenormalityofthesampling

Answers
The correct interpretation of the interval is:
B. We are 95 percent confident that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
The conditions for inference that have been met are: D. I and III only.
For the first question, the correct interpretation of the confidence interval is:
B. We are 95 percent confident that the difference in population means for miles traveled by the two companies is between 1.86 miles and 2.15 miles.
This interpretation reflects the fact that the confidence interval was constructed based on the sample means, but it provides an inference about the population means of the two companies.
For the second question, the conditions for inference that have been met are:
D. I and III only
I. The data were collected using a random method.
This ensures that the samples are representative of the population.
III. Each sample size is large enough to assume normality of the sampling distribution of the difference in sample means.
This condition implies that the sample sizes are sufficiently large to rely on the central limit theorem, which states that the sampling distribution approaches a normal distribution as the sample size increases.
Condition II, which states that each sample size is less than 10 percent of the population size, is not explicitly mentioned in the question. Therefore, we cannot assume that this condition has been met.
