Answer:
I believe answer B.
the figure below is a net for a triangular prism (Help)
Answer:
368 in²
Step-by-step explanation:
Surface area of the triangular prism is the sum of the area of each net = 2(area of two triangle) + 2(area of two similar rectangles) + area of rectangle
= 2(½*bh) + 2(L*W) + (L*W)
Surface area = 2(½*5*7) + 2(15*8.6) + (15*5)
= 35 + 258 + 75
= 368 in²

Answer:
12
Step-by-step explanation:
a² + b² = c²
a² + 9² = 15²
a² + 81 = 225
a² = 225 - 81
a² = 144
[tex]\sqrt{a^2} =\sqrt{144}[/tex]
a = 12
An experiment to compare the tension bond strength of polymer latex modified mortar (Portland cement mortar to which polymer latex emulsions have been added during mixing) to that of unmodified mortar resulted in x = 18.19 kgf/cm2 for the modified mortar (m = 42) and y = 16.87 kgf/cm2 for the unmodified mortar (n = 32). Let m1 and m2 be the true average tension bond strengths for the modified and unmodified mortars, respectively. Assume that the bond strength distributions are both normal.
(a) Assuming that ?1 = 1.6 and ?2 = 1.3, testH0: m1 ? m2 = 0versus Ha: m1 ? m2 > 0 at level 0.01.State the rejection region(s). (If the critical region is one-sided, enter NONE for the unused region. Round your answers to two decimal places.)

z ?
Compute the test statistic value. (Round your answer to two decimal places.)
z =
State the conclusion in the problem context.
Reject H0. The data does not suggest that the difference in average tension bond strengths exceeds 0.
Fail to reject H0. The data does not suggest that the difference in average tension bond strengths exceeds from 0.
Fail to reject H0. The data suggests that the difference in average tension bond strengths exceeds 0.
Reject H0. The data suggests that the difference in average tension bond strengths exceeds 0.
(b) Compute the probability of a type II error for the test of part (a) when m1 ? m2 = 1.(Round your answer to four decimal places.)
(c) Suppose the investigator decided to use a level 0.05 test and wished ? = 0.10 when m1 ? m2 = 1. If m = 42, what value of n is necessary? (Round your answer up to the nearest whole number.)
n =
(d) How would the analysis and conclusion of part (a) change if ?1 and ?2 were unknown but s1 = 1.6 and s2 = 1.3?
Since n = 32 is not a large sample, it would no longer be appropriate to use the large sample test. A small sample t procedure should be used, and the appropriate conclusion would follow.
Since n = 32 is a large sample, it would be more appropriate to use the t procedure. The appropriate conclusion would follow. Since n = 32 is a large sample, it would no longer be appropriate to use the large sample test. Any other test can be used, and the conclusions would stay the same.
Since n = 32 is not a large sample, it still be appropriate to use the large sample test. The analysis and conclusions would stay the same.

Answer:
this is 4(2x−3)=4(2x)−4(3)distributive property
Answer:
The Distributive Property
Step-by-step explanation:
The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. The division property of inequality states that two unequal values divided by a positive number retain the same relationship.

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 60 m, find its length and width.
Answer:
120 m
Step-by-step explanation:
.
Answer:
length = 20m
width = 10m
Step-by-step explanation:
perimeter = 2 (length + width)
length = 2 * width = 2w
perimeter = 2 (2w +w)
perimeter = 2(3w)
60m = 6w
(divide both sides by 6)
60/6 = w
width = 10m
length = 2w
so length = 2 * 10 = 20m
A recipe for pie please help me please
Answer:
Apple Pie (This recipe is from TasteofHome I did not make it)
Step-by-step explanation:
Ingredients
1/2 cup sugar
1/2 cup packed brown sugar

1 teaspoon ground cinnamon
1/4 teaspoon ground ginger
1/4 teaspoon ground nutmeg
6 to 7 cups thinly sliced peeled tart apples
1 tablespoon lemon juice
Dough for double-crust pie
1 tablespoon butter
1 large egg white
Additional sugar
Directions
Preheat oven to 375°. In a small bowl, combine sugars, flour and spices; set aside. In a large bowl, toss apples with lemon juice. Add sugar mixture; toss to coat.
On a lightly floured surface, roll one half of dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim even with rim. Add filling; dot with butter. Roll remaining dough to a 1/8-in.-thick circle. Place over filling. Trim, seal and flute edge. Cut slits in top. Beat egg white until foamy; brush over crust. Sprinkle with sugar. Cover edge loosely with foil.
Bake 25 minutes. Remove foil; bake until crust is golden brown and filling is bubbly, 20-25 minutes longer. Cool on a wire rack.

Answer the following questions
Answer:
Question 1 : -8/3
Question 2 : 7.62 or unrounded 7.615773106.
Step-by-step explanation:
Question 1:
( 2 , 4 ) ( 5 , -4)
^ ^ ^ ^
x1 y1 x2 y2
Equation : y2 -y1 / x2 - x1
-4-4/5-2 = -8/3
Question 2 :
Equation : a^2 + b^2 = c^2
3^2 + 7^2 = c^2
3^2 = 9
7^2 = 49
9 + 49 = 58
Square root of 58 = 7.615773106.
34. Find each of the following probabilities when n indepen- dent Bernoulli trials are carried out with probability of success p. a) the probability of no successes b) the probability of at least one success c) the probability of at most one success d) the probability of at least two successes
Answer:
A.) (1 - p)^n
B.) 1 - (1 - p)^n
C.) (1 - p)^n + np*(1-p)^(n-1)
D.) 1 - (1 - p)^n - np*(1-p)^(n-1)
Step-by-step explanation:
General form of a binomial probability :
P(x = x) = nCx * p^x * q^(n-x)
q = 1 - p ; n = number of trials ; x = number of successes ; p = probability of success
A.) probability of no successes ;
P(x = 0) = nC0 * p^0 * (1 - p)^(n-0)
P(x = 0) = 1 * 1 * (1 - p)^n
P(x = 0) = (1 - p)^n
Probability of atleast one success = 1 - P(no success)
P(x ≥ 1) = 1 - P(x = 0)
P(x = 0) = (1 - p)^n
P(x ≥ 1) = 1 - P(x = 0) = 1 - (1 - p)^n
Probability of at most one success
P(x ≤ 1) = p(x = 0) + p(x = 1)
P(x = 0) = (1 - p)^n
P(x = 1) = nC1 * p^1 * (1 - p)^(n-1)
P(x = 1) = n * p * (1 - p)^(n-1) = np*(1-p)^(n-1)
P(x ≤ 1) = (1 - p)^n + np*(1-p)^(n-1)
Probability of atleast two successes:
(1 - probability of at most 2 successes)
P(x ≥ 2) = 1 - P(x ≤ 1)
P(x ≥ 2) = 1 - (p(x = 0) + p(x = 1))
P(x ≥ 2) = 1 - p(x = 0) - p(x = 1))
P(x ≥ 2) = 1 - (1 - p)^n - np*(1-p)^(n-1)

Find the volume of the figure. find the volume Volume =
Answer:
Volume = 13,364 cm³
Step-by-step explanation:
Volume of the figure = volume of trapezoid prism
Volume of trapezoid prism = area of trapezoid base × length of the prism
= ½(a +b)h × l
Where,
a = 15 cm
b = 37 cm
h = 25.7 cm
l = 20 cm
Substitute
Volume = ½(15 + 37)25.7 × 20
Volume = 13,364 cm³
Plz no links just give the answer and how you got it plsss. A circular hot spring has a diameter of 106 meters. Over time, the diameter of the spring decreases by 2 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for pi
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
