Step-by-step explanation:
Leo designs a stand for the new statue on display at the local library. The stand is in the shape of a right trapezoidal prism. The base of the prism has an area of 4 ft^2 and the prism stands 2.4 feet high. As Leo paints the stand, he calculates the surface area of the stand to be 32 ft^2.
(a) Leo is asked to purchase roping that will be used to close off the area around the statue. He purchases a length that is five times the perimeter of the stand in roping. How much roping does he purchase?
(b) Leo plans to add gold leaf to the sides of the stand but not to the two bases. What percent of the area of the stand will have gold leaf? Round your answer to the nearest whole number.
Answer:
See below ~
Step-by-step explanation:
(a)
Formula
Surface Area = (2 x Base Area) + (Perimeter x Height)Solving
32 = 2 x 4 + (P + 2.4)P + 2.4 = 4P = 1.6 ftLength of rope = 5P5 x 1.6Length of rope = 8 feet(b)
Slant height = √(2.4)² + (1)² = √5.76 + 1 = √6.76 = 2.6 feetArea of a side = slant height x lengthArea of a side = 2.6 x 2 = 5.2 square feetTotal area of sides = 5.2 x 2 = 10.4 square feet% (Area) = 10.4/32 = 0.32532.5%33%Mr. Davis took his car to the repair shop.

Answer: 161
[3×2^5+13×(−2)]+7[8−(4−9)]
Calculate 2 to the power of 5 and get 32.
3×32+13(−2)+7(8−(4−9))
Multiply 3 and 32 to get 96.
96+13(−2)+7(8−(4−9))
Multiply 13 and −2 to get −26.
96−26+7(8−(4−9))
Subtract 26 from 96 to get 70.
70+7(8−(4−9))
Subtract 9 from 4 to get −5.
70+7(8−(−5))
The opposite of −5 is 5.
70+7(8+5)
Add 8 and 5 to get 13.
70+7×13
Multiply 7 and 13 to get 91.
70+91
Add 70 and 91 to get 161.
161
Answer:
Step-by-step explanation:
Use PEDMAS
[3 *2⁵ + 13*(-2) ] + 7[8-(4-9) ] = [3*2⁵ + 13*(-2)] +7[ 8 - (-5) ]
{calulate the inner most parentesis (4- 9 = -5)}
= [3*32 + 13*(-2) ] + 7* [ 8+5]
{Find the exponent 2⁵ = 32}
= [ 96 + (-26) ] + 7* 13
{Here 3 & 32 aree multiplied & 13 and (-2) are multiplied and 8 is added to 5}
= 70 + 91
= 161

Answer:
The answer is 2x+5.
Step-by-step explanation:
In some countries, people believe that blood type has a strong impact on personality. For example, Type B blood is thought to be associated with passion and creativity. A statistics student at a large U. S. University decides to test this theory. Reasoning that people involved in the arts should be passionate and creative, she takes a simple random sample of students majoring or minoring in arts at her university and asks them for their blood type. Here are her results:
Observed number of performing arts majors with each blood type
Type A Type B Type AB Type 0 Total
50 23 10 67 150
Assume the distribution of blood type among all U. S. Residents is as follows:
Type A: 42%; Type B: 10%; Type AB: 4%; Type O: 44%.
(a) The student wants to carry out a test of significance to see if the distribution of blood types among arts majors or minors is different from the U. S. Distribution. State the null and alternative hypotheses for this test.
(b) Find the expected counts for each blood type under the assumption that the null hypothesis is true.
(c) Discuss whether the conditions for this test have been met.
(d) Find the value of the test statistic and the P-value of the test, and make the appropriate conclusion. Use α = 0. 5.
(e) Based on your answer to (d), which error is it possible that you have made, Type I or Type II? Describe that error in the context of the problem
The null hypothesis for the test regarding the blood type is that they distribution of blood types among art major is the same as the US distribution.
What is a null hypothesis?It should be noted that null hypothesis simply suggests that there is no statistical relationship.
Here, the null hypothesis for the test regarding the blood type is that the distribution of blood types among art major is the same as the US distribution and the alternative hypothesis is that the distribution of blood types among art major is different from the US distribution.
The conditions for this test have been met as all expected frequencies are greater than 5.
Since the test statistic is 9.63 and the p-value is 0.022, one can reject the null hypothesis. Therefore, it'll be concluded that the distribution of blood types among arts majors and minors is different from the U.S distribution.

Can someone help me please!!
Answer:
40°
Step-by-step explanation:
The red 75° curve means that both angles must sum up to 75°The question provides two angles 35° and n°Using math, you can do:n° + 35° = 75°Subtracting 35° from both sides of the equation:n° = 75° - 35° = 40°Answer:
40°
Step-by-step explanation:
if the measurement of the two angles combined is 75 and one of the angles is 35, we can subtract 35 from 75 to get 40, which should be the answer for n, and you can check it by adding 40 and 35 to get 75, the total of both angles

Events A and B are overlapping.
P(A) =4/11 ; P(B) =3/11 , P(A and B) = 2/11.
Find P(A or B).
7/11
5/11
8/11
9/11
5/11 is the final answer.
P(A) = 4/11P(B) = 3/11When events are overlapping
formula: P(A or B) = P(A) + P(B) - P(A and B)
=======
P(A or B) = 4/11 + 3/11 - 2/11
P(A or B) = 7/11 - 2/11
P(A or B) = 5/11
Answer:
5/11
Step-by-step explanation:
Given:
P(A) = 4/11P(B) = 3/11P(A ∩ B) = 2/11We can construct a Venn diagram to help answer this question (see attached).
Place 2/11 in the overlapping part. Then calculate the remaining probabilities:
P(A) - P(A ∩ B) = 4/11 - 2/11 = 2/11
P(B) - P(A ∩ B) = 3/11 - 2/11 = 1/11
P(A' ∩ B') = 1 - 5/11 = 6/11
So P(A ∪ B) = 2/11 + 2/11 + 1/11 = 5/11

When a bill is not paid by the due date, a late fee is added each month until the bill is paid. The values in the table represent the total amount due, in dollars, for each month that a payment remains overdue. Using x for the number of months overdue and y for the total amount due, in dollars, construct a linear function that describes the relationship between the number of months the bill is overdue and the total amount due. Enter the equation of the function in the box, and use paper to show your work
Bill + (Late fee x months) = Final bill
FunctionsGiven that when a bill is not paid by the due date, a late fee is added each month until the bill is paid, to construct a linear function that describes the relationship between the number of months the bill is overdue and the total amount due you must perform the following calculation:
Bill + (Late fee x months) = Final billThus, if the bill is $1000 and the late fee is $50 per month, and it takes 4 months to regularize the debt, the function would apply as follows:1000 + (50 x 4) = X1000 + 200 = X1200 = XLearn more about functions in https://brainly.com/question/12431044

What are the solutions of -x2 + 4x = x - 4?
O-5 and 0
0-5 and -1
0-1 and 4
O and 4
Answer:
-1 and 4
Step-by-step explanation:
first you bring the terms on the right side to the left and you get:
-x^2 + 3x + 4 = 0
then you divide both sides of the quadratic by -1:
x^2 - 3x - 4 = 0
then you factor the equation:
(x + 1)(x - 4) = 0
for any product to be zero, one of the factors must be zero. hence, either x + 1 or x - 4 can be zero. so x can be -1 and//or 4.
