A rectangular prism with length 12 m , width 8 m & height 15 m , find its surface area .

Answers

Answer 1

Answer: [tex]792\ m^2[/tex]

Step-by-step explanation:

Given

The length of the rectangular prism is [tex]l=12\ m[/tex]

width of the rectangular prism is [tex]w=8\ m[/tex]

height of the rectangular prism is [tex]h=15\ m[/tex]

The surface area of the rectangular prism is [tex]2[wl+lh+hw][/tex]

Put the values

[tex]\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2[/tex]

The surface area of the rectangular prism is [tex]792\ m^2[/tex]

Answers

Answer:

area = 24 units squared

Step-by-step explanation:

area = 1/2 (base 1 + base 2) x height

area = 1/2 (4 + 8) x 4

area = 1/2 (12) x 4

area = 6 x 4

area = 24

24 is the correct answer

Answers

Answer:

Step-by-step explanation:

A

For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

What are quartiles?

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.

Similarly, second quartile (also called median) is approximately in mid of the data.

Third quartile (also called upper quartile)  has approx 75% in its left partition, and on its right lies approx 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.

Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

left rectangle = l x w = 20 x 6 = 120

middle square = l x w = 8 x 9 = 72

lower right triangle = height is 12 because (26-8-6), so 1/2 bh =1/2 (9)(12) = 54

A wedding website states that the average cost of a wedding is $25,809. One concerned bride hopes that the average is less than reported. To see if her hope is correct, she surveys 46 recently married couples and finds that the average cost of weddings in the sample was $24,638. Assuming that the population standard deviation is $5531, is there sufficient evidence to support the bride’s hope at the 0.10 level of significance?
Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below.
H0Ha: μ=25,809: μ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯25,809
Step 2 of 3 : Find the test statistic
Step 3 of 3 : What is the conclusion?

Answers

Answer:

1)

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

2) Test Statistic = -1.44

3) Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Step-by-step explanation:

Given the data in the question;

Sample mean x" = 24,638

sample size n = 46

standard deviation σ = 5531

level of significance ∝ = 0.10

NULL and ALTERNATIVE HYPOTHESIS

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

TEST STATISTICS

Z = (x"-μ) / σ√n

we substitute

Z = (24,638 - 25,809) / (5531/√46)

Z = -1171 / 815.5

Z = -1.44

Test Statistic = -1.44

Now, from normal z-table;

P-value = P( Z < -1.44 ) = 0.0749

P-value = 0.0749

Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.

Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Solve for n.

Answers

Answer:

n = 1/2 or .5

Step-by-step explanation:

4n + 3 = 10 -10n

14n = 7

n = 1/2 or .5

Hope this helps!

Answer:

n = -0.5

Step-by-step explanation:

4n + 3 = 5(2 - 2n)

First you multiply 2 and 2n by 5

4n + 3 = 10 - 10n

subtract 4n on both sides (meaning subtract 4n by itself on the left side of the equal sign and subtract 10n and 4n)

3 = 10 + 14n

Subtract 10 on both sides

-7 = 14n

Divide on both sides

Your answer should be n = -0.5 (or -0.5 = n)

Hope this helps!
