Answer:

  about 15 or 16 items

Step-by-step explanation:

The break-even point is where revenue is equal to cost.

  150x = 7x +2200

  143x = 2200 . . . . . . . subtract 7x

  x ≈ 15.38 . . . . . . . . . . divide by 143 (multiply by the inverse of 143)

__

When 15 items are sold, revenue doesn't quite cover costs. Costs still exceed revenue by 55. When 16 items are sold, revenue exceeds costs by 95. (I would call this the break-even point, because I prefer a slight profit over a slight loss.)

Step-by-step explanation:

Given

Required

[tex]g(2)[/tex]

To solve this, we make use of:

[tex]g(x) = |7 - x^2|[/tex]

Because [tex]x \le 2[/tex]

i.e. [tex]2 \le 2[/tex]

So, we have:

[tex]g(2) = |7 - 2^2|[/tex]

[tex]g(2) = |7 - 4|[/tex]

[tex]g(2) = |3|[/tex]

Remove absolute brackets

Answer:

Step-by-step explanation:

3/5x+30=150

We move all terms to the left:

3/5x+30-(150)=0

Domain of the equation: 5x!=0

x!=0/5

x!=0

x∈R

We add all the numbers together, and all the variables

3/5x-120=0

We multiply all the terms by the denominator

-120*5x+3=0

Wy multiply elements

-600x+3=0

We move all terms containing x to the left, all other terms to the right

-600x=-3

x=-3/-600

x=1/200

The histogram shows the distribution of the newly planted trees

The dataset is given as:

3.2, 4.3, 3.5, 5.4, 3.7, 5.5, 6.2, 3.1, 6.8, 7.1, 4.8, 6.5, 4.9, 5.3, 5.9

Sort the data elements

3.1, 3.2, 3.5, 3.7, 4.3, 4.8, 4.9, 5.3, 5.4, 5.5, 5.9, 6.2, 6.5, 6.8, 7.1

Calculate the range

Range = Highest - Least

This gives

Range = 7.1 - 3.1

Range = 4

Divide by 4 to calculate the class width

Width = 4/4

Width = 1

So, the classes and the frequencies are:

Class               Frequency

3.1 - 4.0              4

4.1 - 5.0              3

5.1 - 6.0             4

Answer:Step-by-step explanation:

Answer: The histogram is skewered to the right (right-skewered)

Step-by-step explanation:

The peak veers to the left and the tail is towards the right.

The histogram given is right-skewed.

A histogram is a representation of the distribution of data with intervals.

We have,

Right-skewed and left-skewed are terms used to describe the shape of a data distribution.

A right-skewed (or positively skewed) distribution is one in which the tail on the right-hand side of the graph is longer or fatter than the tail on the left-hand side.

A left-skewed (or negatively skewed) distribution is the opposite of a right-skewed distribution.

In this case, the tail on the left-hand side of the graph is longer or fatter than the tail on the right-hand side.

Now,

We see that the histogram given is right-skewed because the tail on the right-hand side of the graph is longer or fatter than the tail on the left-hand side.

Thus,

The histogram given is right-skewed.

Answer:

Both companies claim that their batteries last longer than the average alkaline battery is true .

Step-by-step explanation:

Both companies claim that their batteries last longer than the average alkaline battery  is true because most of the batteries of these companies  did passed the test to last longer.

As we can project from that table given that around 77% Energized batteries passed the test and around 67% powered cell  batteries passed the test.

Step-by-step explanation:

equation: $41.63 - 4.19 = 37.44

solve: 37.44 ÷ 6 = 6.24.

hope this helped!

Answer:

He pays a TOTAL of $41.63. Meaning everything is equal to that value

He pays 4.19$ for Milk

He buys 6bags of Oranges and each of these cist the same amount.. let's say x.

So 6 bags would cost 6x

So Total is

6x + 4.19 =41.63

6x= 41.63-4.19

6x=37.44

x=37.44/6

x=$6.24

To check this

6x + 4.19 should equal 41.63$

6(6.24) + 4.19= $41.63

Answer:

Step-by-step explanation:

The ΔDGF and ΔABC can be proven similar through SSS similarity. Therefore, option D is the correct answer.

We need to find which of the given pairs of triangles can be proven similar through SSS similarity.

If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.

Now, form option D.

DF/AB=DG/AC=FG/BC

⇒8/2=10/2.5=11/2.75

⇒4=4=4

Thus, ΔDGF and ΔABC are similar.

Answer:

a) -6 mpg.

b) 2.77 mpg

c) The 95% confidence interval for the difference of population mean gas mileages for engines A and B and interpret the results, in mpg, is (-8.77, -3.23).

Step-by-step explanation:

To solve this question, we need to understand the central limit theorem, and subtraction of normal variables.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Gas mileage A: Mean 36, standard deviation 6, sample of 50:

So

[tex]\mu_A = 36, s_A = \frac{6}{\sqrt{50}} = 0.8485[/tex]

Gas mileage B: Mean 42, standard deviation 8, sample of 50:

So

[tex]\mu_B = 42, s_B = \frac{8}{\sqrt{50}} = 1.1314[/tex]

Distribution of the difference:

Mean:

[tex]\mu = \mu_A - \mu_B = 36 - 42 = -6[/tex]

Standard error:

[tex]s = \sqrt{s_A^2+s_B^2} = \sqrt{0.8485^2+1.1314^2} = 1.4142[/tex]

A. Find the point estimate.

This is the difference of means, that is, -6 mpg.

B. Find the margin of error

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = zs = 1.96*1.4142 = 2.77[/tex]

The margin of error is of 2.77 mpg

C. Construct the 95% confidence interval for the difference of population mean gas mileages for engines A and B and interpret the results(5 pts)

The lower end of the interval is the sample mean subtracted by M. So it is -6 - 2.77 = -8.77 mpg

The upper end of the interval is the sample mean added to M. So it is -6 + 2.77 = -3.23 mpg

The 95% confidence interval for the difference of population mean gas mileages for engines A and B and interpret the results, in mpg, is (-8.77, -3.23).

Answer:

a, b, c, e

Step-by-step explanation:

4(2n + 1) = 52 is the same as 52 = 8n + 4 if you use distributive property.

4 = 52 - 8n is the same as 52 = 8n + 4. The 8n is just subtracted from both sides.

4n = 48 is not the same as 4(2n + 1) = 52 or 52 = 8n + 4 or 4 = 52 - 8n.

n = 6 is the solution to the equation so it is equivalent.

2/B

Step-by-step explanation:

The base is 9 and the height is 4.

The values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively

The function is given as:

f(x) = 5^2x

For f(-1), we have x = -1

This gives

f(-1) = 5^(2 * -1)

f(-1) = 0.04

For f(0), we have x = 0

This gives

f(0) = 5^(2 * 0)

f(0) = 1

For f(2), we have x = 2

This gives

f(2) = 5^(2 * 2)

f(2) = 625

Hence, the values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively
