A box in the shape of a triangular prism is painted for a project. Which formula would be used to find the lateral surface area of the triangular prism?

Answers

Answer:

LSA = (a+b+c)×h

Step-by-step explanation:

The formula that would be used to find the lateral surface area of the triangular prism = perimeter of base(P) × Height of prism(H)

Let us assume that three side of triangle are a, b, c and height of prism is h

Then lateral surface area of the prism can be LSA = (a+b+c)×h

Answers

Answer:

Mean = $54.67

Step-by-step explanation:

How to Find the Mean

Add up all data values to get the sum

Count the number of values in your data set

Divide the sum by the count

The mean is the same as the average value in a data set.

Mean Formula

The mean x of a data set is the sum of all the data divided by the count n.

mean=x¯¯¯=∑ni=1xin

Solve

Add up all data values to get the sum

$29 + $58 + $15 + $129 + $75 + $22 = $328

Count the number of values in your data set

$29 and $58 and $15 and $129 and $75 and $22 = 6

Divide the sum by the count

328 ÷ 6 = 54.6666666667

Nearest tenth = 54.67

Therefore, the Mean = $54.67

At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $20. Other bank managers at the meeting suggested that this statement may be in error and it needs to be tested. The file called Bank Call Center attached below, contains data for a random sample of 67 customers from the call center population. What should be conducted based on the sample data? Test using α = 0.10

Answers

Answer:

As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

Step-by-step explanation:

As the standard deviation for the past due amounts is 63

The sample size n= 67

1) Formulate the null and alternate hypothesis

H0: u ≤ 23 against the claim Ha: u > 23

2)  The test statistics is

Z= x- u / σ/ √n

z= 20- 23/ 63/ √67

z= 0.00581

z= 0.006

3) The significance level ∝= 0.1

4) The critical value for ∝= 0.1 is Z > ±2.33

5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

In a tennis club the ratio number of junior members : number of senior members is
7 : 10. There are 18 more senior members than junior members. Find the total amount of club members.

Answers

Answer:

35 members

Step-by-step explanation:

In a tennis club the ratio number of junior members : number of senior members is 7 : 10

From the above ratio

Number of junior member = 7

Number of senior members = 10

There are 18 more senior members than junior members.

S = 18 + j

10 + 18 = 28 senior members

Hence,

Total number of members = 28 senior members + 7 junior members

= 35 members


In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.

Answers

Given:

A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.

To find:

The area of the blue sector.

Solution:

Area of a sector is:

[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]

Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.

Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get

[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]

[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]

[tex]A=33.49333....[/tex]

Approximate the value to the nearest tenth.

[tex]A\approx 33.5[/tex]

Therefore, the area of the blue sector is about 33.5 sq. units.

Step-by-step explanation:

The function f is defined by f(x) = x^2-2x-24
if f (x + 3) = x^2+kx-21, what is the value of k?

Answers

Step-by-step explanation:

my guess it's 4

(x+7) (x-3)

The value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

How to evaluate a given mathematical expression with variables if values of the variables are known?

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

It is given that:

[tex]f(x) = x^2 -2x - 24[/tex]

and [tex]f(x+3) = x^2 + kx - 21[/tex]

Putting x = x+3 in the definition of f(x), we get:

[tex]f(x+3) = (x+3)^2 -2(x+3) -24\\\\f(x+3) = x^2 + 6x + 9 -2x -6 - 24\\\\f(x+3) = x^2 + 4x -21[/tex]

Comparing it with [tex]f(x+3) = x^2 + kx - 21[/tex], we see that k is having value as 4 for the considered function.

Thus, the value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

70% of all US adults drink the cereal milk

Find the standard deviation of the sampling
distribution of p

Answers

Answer: 0.0188

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the standard deviation of the sampling  distribution of p is 0.0144.

Central Limit TheoremBy the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].

In this problem:

Suppose that 70% of all US adults drink the cereal milk, hence [tex]p = 0.7[/tex].A sample of 1012 adults is taken, hence [tex]n = 1012[/tex].

Then, the standard deviation is:

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{1012}} = 0.0144[/tex]

The standard deviation of the sampling  distribution of p is 0.0144.

Answers

Answer:

The answer is "lengths of opposite sides are equal "

Step-by-step explanation:

The parallelogram is a four-sided one in parallel opposites and therefore opposite angles equal. Each quadrilateral is called a rhombus with equal sides, as well as a parallelogram that also has correct angles is recognized as a rectangle. Its flat form with 4 smooth edges is parallel on the other side, so that when the opposite sides were equal in length. That's why ABCD is also a parallelogram because the two sides are parallel.

If the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes, how many beakers are there?

Answers

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes.

Let the beakers be 3x and the number of test tubes be 8x

The number of test tubes =8x=64
