Answer: The point estimate for this population proportion is 0.2
Step-by-step explanation:
The point estimate for this population proportion is also referred to as the sample proportion. This is also known as the probability of success, p. The formula for determining p is expressed as
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 200
x = 40
p = 40/200 = 0.2
When the polynomial x^4-3x^3-7x^2+7x+2 is divided by x+2 the quotient is x^3 +Bx^2 +Cx +1. Find the value of B +C
Answer:
B=-5
C=3
Step-by-step explanation:
x^4-3x^3-7x^2+7x+2= x^4-3x^3-10x^2+3x^2+7x+2
=x^4-3x^3-10x^2+ 3x^2+7x+2
=x^2(x^2-3x-10)+ 3x^2+7x+2
=x^2(x^2+2x-5x-10)+ 3x^2+6x+x+2
=x^2(x(x+2)-5(x+2))+ 3x(x+2)+1(x+2)

Answer:
A
Step-by-step explanation:
Answer:
6^2+11^2 = c^2
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2+11^2 = c^2

Answer:
The only statement that is NOT true is option A.
- If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
Step-by-step explanation:
Complete Question
Ellen is opening. Cookie shop eat a local middle school . She randomly surgery’s students to determine The types of cookies they would buy at the cookie shop the results of the surveys are below based on the survey. Which statement is not true?
Cookie Survey
Type of Cookie | Number of Students
Chocolate Chip | 25
Oatmeal Raisins | 15
Peanut Butter | 22
Sugar | 18
A) If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
B) 22½% of the students surveyed would buy a sugar cookie.
C) If 240 students were to purchase a cookie from the store, approximately 66 students will purchase a peanut butter cookie.
D) Half of the students prefer chocolate chips or oatmeal raisin cookies.
Solution
First of, we obtain the proportion or percentages of students surveyed that buy each type of cookie.
Each of that is the number of students that buy the type of cookie in the sample divided by the Total number of students sampled.
Total number of students sampled = 25 + 15 + 22 + 18 = 80
Type of Cookie | N | proportion | %
Chocolate Chip | 25 | 0.3125 | 31.25%
Oatmeal Raisins | 15 | 0.1875 | 18.75%
Peanut Butter | 22 | 0.2750 | 27.50%
Sugar | 18 | 0.2250 | 22.50%
Now, taking the statements one by one
A) If 160 students buy a cookie, approximately 18 students would buy a sugar cookie.
Proportion of students that buy sugar cookie in the sample = 0.225
Number of students that will buy sugar cookie amongst 160 students = np = 160 × 0.225 = 36 students.
This statement is false, that is, NOT true.
B) 22½% of the students surveyed would buy a sugar cookie.
From the table, 22.5% of the students surveyed bought a sugar cookie. Hence, no matter the number of students, the percentage of students that will buy a sugar cookie will approximately be 22.5%.
This statement is True.
C) If 240 students were to purchase a cookie from the store, approximately 66 students will purchase a peanut butter cookie.
Proportion of students that buy peanut butter cookie in the sample = 0.275
Number of students that will buy peanut butter cookie amongst 240 students = np = 240 × 0.275 = 66 students.
This statement is true.
D) Half of the students prefer chocolate chips or oatmeal raisin cookies.
Proportion of students that buy chocolate chips or oatmeal raisin cookies in the sample = 0.3125 + 0.1875 = 0.50
0.50 is half of the distribution.
Hence, this statement too, is True.

A stunt man wants to drive a car off a ramp at an angle of 35∘ from the ground. He already has a ramp with an angle of 15∘. He plans to add a second ramp on top to increase the angle to 35∘. What angle measure does the second ramp need to have?
The second ramp needs to have an angle of 20° from the ground to achieve the overall angle of 35° for the car to drive off smoothly and reach the desired height.
Here,
To find the angle measure the second ramp needs to have, we can use the concept of angles of elevation and depression.
When the car drives off the first ramp, it will be going at an angle of 15° from the ground, and the angle of elevation from the ground to the car will also be 15°.
This is because the angle of elevation is the angle between the horizontal line and the line of sight from the ground to an object above the ground.
Now, when the car reaches the top of the first ramp, it will be at the same level as the second ramp.
At this point, the car needs to continue its ascent with an additional angle of 20° (35° - 15°) to reach the desired angle of 35° from the ground.
So, the second ramp needs to have an angle of 20° from the ground to achieve the overall angle of 35° for the car to drive off smoothly and reach the desired height.

Someone help me pleaseeeee
Answer:
36°.
Step-by-step explanation:
To find this, we will simply need to know that the sum of the angles of a triangle is 180°. This means that in order to find the measure of the third angle, we will need to subtract the others from 180°.
180 - 99 - 45 = 36°.
The measure of the third angle is 36°.
A burrito restaurant used the given table to keep track of the numbers of different types of burritos that were sold and the kinds of beans that people requested. Consider the following events: A. The burrito is a chicken burrito. B. The burrito is a carne asada burrito. C. The customer requested black beans. D. The customer requested pinto beans. Which two events are independent?
Answer: B and D
yee yee
Two events are independent if the occurrence of one event does not affect the probability of the other event occurring.
What is probability?A probability of an event is a number in science that indicates how likely the event is to occur.
It is expressed as a number between 0 and 1, or as a percentage between 0% and 100% in percentage notation. The higher the probability, the more likely the event will occur.
Two events are considered independent if the occurrence of one event has no effect on the likelihood of the other event occurring.
We can see that events A and B are independent in this case because the type of meat in the burrito has no effect on the likelihood of the customer requesting a specific type of beans.
Similarly, events C and D are independent because the type of beans requested does not depend on the type of meat in the burrito.
Thus, events A and B are independent and events C and D are independent.

Determine the volume of the cylinder
Answer:
V = πr²h
To determine the volume of a cylinder you have to multiply the area of the base by the height of the cylinder.
Step-by-step explanation:
The base of a cylinder is a circle. So we must find the area of the circle first. (Which is πr²)
Then we multiply the height by the area of the circle.
V = π·r²·h
This can be used in different ways as well,
if we don't know the radius but know everything else we could use the formula:
[tex]r=\sqrt{\frac{V}{\pi*h} }[/tex] (r = √(V/πh))
If we don't know the height we use this formula:
(h = V/(πr²))
A cone is cut by a plane parallel to its base. The small cone on top is similar to the large cone, with a similarity ratio of 1 : 2. The ratio between the volume of the small cone to that of the frustum is _ : _.
Answer:
1:1Step-by-step explanation:
The ratio between the volume of the small cone to that of the frustum is 1:1.
Notice that the bigger cone is double than the smaller cone, which means the smaller cone is half of the volume of the bigger cone, if you wipe the small one, you would have the frustum with the same volume as the wiped part, because if you delete the smaller cone, you would be deleting half volume of the bigger cone, giving at the end a relation 1 : 1 between the frustum and the smaller cone.

What are the x-intercept and the y-intercept of the graph of 8x – 7y = -56?
Answer:
x-intercept
y=0
8x - 7(0)= -56
8x = -56
x = -7
(-7, 0)
y-intercept x= 0
8(0) -7y = -56
-7y = -56
y = 8
(0, 8)
Step-by-step explanation:
The x - intercept of the equation is, (- 7, 0)
The y - intercept of the equation is, (0, 8)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 8x - 7y = - 56
Now, We have to find the x - intercept as;
Substitute y = 0,
⇒ 8x - 7×0 = - 56
⇒ 8x = - 56
⇒ x = - 56/8
⇒ x = - 7
And, We have to find the y - intercept as;
Substitute x = 0,
⇒ 8x - 7y = - 56
⇒ 8×0 - 7y = - 56
⇒ - 7y = - 56
⇒ 7y = 56
⇒ y = 56 / 7
⇒ y = 8
