Answers

The distribution of the cars is an illustration of percentages

The main street has 100 or more cars per hour for 66.7% of the time

How to determine the time percentage?

The dataset is given as:

20 60 100 140 180 120

From the above dataset, we have:

100 or more cars = 4Total distribution of cars = 6

The percentage is then calculated as:

Percentage= 4/6 * 100%

Evaluate the product

Percentage= 66.7%

Answers

Answer:

the monthly payment would be 836.22

Step-by-step explanation:

you would find the loan amount which is 190,000 -10% of 190,000 which is 190,000 - 19,000=171,000

then you put the numbers in on a calculator which im using a spreadsheets/ excel

The side lengths in yards of a triangle and a square are shown in the diagram. The perimeter of the triangle is equal to the perimeter of the square. What is the value of x?

Answers

The value of x given the perimeter of the square is 6.

What is the value of x?

The first step is to determine the perimeter of the square.

Perimeter of the square = 4 x length

4 x 2.5x = 10x yards

The perimeter of the triangle is equal to the sum of the three side lengths

2x + 4x - 2 + 2x + 14 = 10x

x= 31
(Round to two decimal places as needed.)
Z=

Answers

Answer:

The z-test statistic for a hypothesis test in which the null hypothesis states that the population proportion, p, equals 0.14 if the following sample information is present (n = 200; x = 31) is z = .6114.

Step-by-step explanation:

The z-test statistic formula is:

[tex]\displaystyle z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

We are given x = 31 and n = 200, so we can solve for [tex]\hat{p}[/tex] : 31/200 = .155.

The population proportion, [tex]p=.14[/tex], is given in the problem.

We can substitute the known values into the z test statistic formula:

[tex]\displaystyle z = \frac{.155-.14}{\sqrt{\frac{.14(.86)}{200} } }[/tex][tex]\displaystyle z=\frac{.015}{\sqrt {.000602}}[/tex][tex]z=.6114[/tex]

The z-test statistic for this problem is z = .6114.

Nancy put new insulation in her attic and discovered that her heating bill for December decreased from $160 to $100. What is the percent decrease?
The amount of decrease is ______?

Answers

Answer:

37.5% decrease

Step-by-step explanation:

To find a relative percentage you generally follow the rule of part divided by whole.

$100 / $160 = .625 (62.5%)

So $100 is 62.5% of $160

To find the decrease we need to subtract 62.5% from 100%

100 - 62.5 = 37.5

Have a great day

The vertex of the function is (-4, -6), the axis of symmetry is x= -4 and the y-intercept is (0, 10).

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is y=x²+8x+10.

Rewrite in vertex form and use this form to find the vertex (h, k).

(-4, -6)

The axis of symmetry is x= -4

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x-intercept(s): (-4+√6, 0), (-4-√6, 0)

y-intercept(s): (0, 10)

Therefore, the y-intercept is (0, 10).

Answers

Answer:

Step-by-step explanation:

All that matters here is # of bottles sold * profit per bottle.

If you multiply these 2 values for each row you will see the blue label has the highest amount of profit.

Among all the product ranges blue label generated the most profit of $5625.

What is profit?

Profit is basically the difference between the total revenue and the total cost of the product.

Profit=Total Revenue- Total cost.

How to calculate profit?

We know that Average profit= total profit/ number of units.

So the profit will be as average profits* number of units.

So the profit of product ranges will be =average profit * number of bottles.

Profit of red label=1.12*3000

=$3360

Profit of black label=1.5*2000

=$3000.

Profit of gold label=2.75*1000

=$2750

Profit of white label=1.20*2750

According to the Mars company, packages of milk chocolate M&Ms contain 20% orange candies. Find the probability that in a random sample of 100 M&M candies, there are between 18% and 22% orange candies.​

Answers

Using the normal distribution, it is found that there is a 0.383 = 38.3% probability that the sample proportion is between 18% and 22%.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

In this problem, the proportion and the sample size are of p = 0.2 and n = 100, respectively, hence:

[tex]\mu = p = 0.2[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.2(0.8)}{100}} = 0.04[/tex]

The probability that in a random sample of 100 M&M candies, there are between 18% and 22% orange candies is the p-value of Z when X = 0.22 subtracted by the p-value of Z when X = 0.18, hence:

X = 0.22:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.22 - 0.2}{0.04}[/tex]

Z = 0.5

Z = 0.5 has a p-value of 0.6915.

X = 0.18:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.18 - 0.2}{0.04}[/tex]

Z = -0.5

Z = -0.5 has a p-value of 0.3085.

0.6915 - 0.3085 = 0.383.

0.383 = 38.3% probability that the sample proportion is between 18% and 22%.

Answers

Answer:

A

Step-by-step explanation:

In an inscribed quadrilateral, opposite angles are supplementary.

An exterior angle of a quadrilateral is supplementary to the adjacent interior angle.

Since the exterior angle is supplementary to both the adjacent interior angle and to the opposite interior angle, the exterior angle and the opposite interior angle are congruent.

The maximum height of the volleyball wag 23 feet.
If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.
The graph that models the volleyball's height over time is exponential.
The volleyball was served from a height of 5 feet.

Answers

Answer:

1,2, and 5

Step-by-step explanation:

The statements about the function that are correct are:

The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.

We have,

The function h(t) = -2(t - 3)2 + 23 represents the height, in feet, t seconds after a volleyball is served.

Let's analyze each statement:

The volleyball reached its maximum height at 3 seconds.

This statement is correct.

The function h(t) is a quadratic function, and its graph is a parabola that opens downwards.

The vertex of the parabola represents the maximum height of the volleyball.

In this case, the vertex occurs when t = 3 seconds.

The maximum height of the volleyball was 23 feet.

This statement is also correct.

We can see from the function that the maximum height occurs at t = 3 seconds, and substituting t = 3 into the function gives:

h(3) = -2(3 - 3)2 + 23 = 23 feet.

If the volleyball is not returned by the opposing team, it will hit the ground in 5.5 seconds.

This statement is incorrect.

To find when the volleyball hits the ground, we need to find when h(t) = 0. Solving -2(t - 3)2 + 23 = 0 gives t = 3 ± √(23/2).

Since the vertex is at t = 3 seconds, the volleyball will hit the ground at the same height it was served, which is h(0) = -2(0 - 3)2 + 23 = 5 feet.

So the time it takes for the volleyball to hit the ground is when h(t) = 0, which occurs at t = 3 ± √(23/2), not 5.5 seconds.

The graph that models the volleyball's height over time is exponential.

This statement is incorrect.

The function h(t) is a quadratic function, not an exponential function.

The volleyball was served from a height of 5 feet.

This statement is also incorrect.

The function h(t) gives the height of the volleyball above the ground, not above the height it was served.

However, we can see from the function that h(0) = -2(0 - 3)2 + 23 = 5 feet, so the volleyball was served from a height of 5 feet above the ground.

Thus,

The statements about the function that are correct are:

The volleyball reached its maximum height at 3 seconds.
The maximum height of the volleyball was 23 feet.
