Answers

Answer 1
To find this z-score, locate the score on the table such that the area of the curve to the right is 0.37. This is similar to the 37th percentile. After locating it, you will see that the z-score is 0.3319.
Answer 2

Using the standard normal table, it is found that the z-score is z = 0.33.

-------------------------

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

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

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the standard normal table and find the p-value associated with this z-score, which is the percentile of X. This p-value is the left-tailed area.The right-tailed area is 1 subtracted by the p-value.

In this problem:

Right-tailed area of 0.37, thus the p-value is of 1 - 0.37 = 0.63.Looking at the standard normal table, the z-score is z = 0.33.

D is the answer to your question
Vertical angles are congruent or equal to each other.

Set the equation:

8x - 8 = 7x + 8

Add 8 to both sides of the equation.

8x - 8 + 8 = 7x + 8 + 8

8x = 7x + 16

Subtract 7x from both sides of the equation.

8x - 7x = 7x - 7x + 16

x = 16

Answer: D) 16

Find the product of 20 x 9 x 5 tell which property you used

Answers

I will be using the associative property. (20 x 9) x 5 = 900
You first multiply 20 x 9, which equals 180, then you multiply 180 x 5, which equals 900.

I used associative property  and the product of 20 x 9 x 5 is 900.

What is associative property?

"The associative property states that when an expression has three terms, they can be grouped in any way to solve that expression. The grouping of numbers will never change the result of their operation. The associative property is true for the cases of addition and multiplication. Neither the sum nor the product of the expression changes."

For the given product of 20 x 9 x 5

I am using the associative property.

(20 x 9) x 5 = 900

First multiply 20 x 9, which gives 180

(180) x 5 = 900

Next multiply 180 x 5, which gives 900.

Hence, I used associative property  and the product of 20 x 9 x 5 is 900.

What value of c would produce a system that has an infinite number of solutions?
Justify your answer.

Explain why there is no value of c that would produce a system with no solution.

Enter your answer, justification, and explanation in the box provided.

Answers

Make the equation the same or a multiple of the other to have an infinite number of solutions. See how the -8/2= -4 and 6/2=3 ? then -2/2 = c
Make c = -1 and they are the same linear equation. (same slope, same intercepts, same line) and therefore have infinite solutions.

In order to have no solutions, the lines cannot cross at all and so they must be parallel but not the same line. Parallel lines have the same slope with different intercepts. if you rearrange both equations in slope intercept form:
y = x/3 - 4/3
y = - cx/3 - 4/3

no matter what you make c the lines will always cross at the y-intercept (0, -4/3). this is a solution and therefore there's no value of c that would produce a system with no solution.

The scale on a map of Texas shows that 1 inch represents 20 miles. The actual distance from Austin to Dallas is 195 miles. On the map, how many inches apart are the two cities?

Answers

1 inch = 20 miles

so 195 miles is 195/20 = 9.75 inches <==
Final answer:

To calculate the map distance between Austin and Dallas with a scale of 1 inch representing 20 miles, and an actual distance of 195 miles, set up a proportion and solve to find that Austin and Dallas would be 9.75 inches apart on the map.

Explanation:

To find out how many inches Austin is from Dallas on the map, we need to set up a proportion. The scale given on the map is 1 inch represents 20 miles. We know the actual distance between Austin and Dallas is 195 miles. To calculate the distance on the map, we use the proportion 1 inch / 20 miles = x inches / 195 miles.

Cross-multiply to solve for x:

(1 inch) * (195 miles) = (20 miles) * (x inches)

195 inch-miles = 20x inch-miles

Now, divide both sides by 20 miles to solve for x:

x = 195 inch-miles / 20 miles

x = 9.75 inches

So, on the map, Austin and Dallas would be 9.75 inches apart.

The distance Margarita covers in [tex]\( \frac{s-5}{4} \)[/tex]hours is  [tex]\( \frac{1}{4} \)[/tex] miles.

Given that Margarita is driving at the speed of [tex]\( \frac{s-4}{s^2 - 9s + 20} \)[/tex] miles per hour, we can express the distance function as:

[tex]\[ d(s) = \text{speed} \times \text{time} = \left( \frac{s-4}{s^2 - 9s + 20} \right) \times s \][/tex]

How is the distance formula like the pythagorean theorem explain?

Answers

The distance formula is simply a variation of the theorem. The method is the same with the Pythagorean however we are now dealing with 2 sets of points instead of 2 lengths. 

In the distance formula, the lengths are derived from the (x1,y1)->(x2,y2) coordinate points and the formula simplified. We still square the difference of x’s and difference of y’s to get our two squares then square root the sum to give our length. While the Pythagorean theorem is directly the sum of the square of the other two sides. 

Nevertheless, both formulas work on the same principle.

Answer:

Both formulas can be used to find the distance between two points on the coordinate plane. The vertical leg of the right triangle represents the difference in the y values of the two points. The horizontal leg of the right triangle represents the difference in the x values of the two points. The hypotenuse of the right triangle represents the distance between the two points.

You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95, what percentage discount is he offering you?

Answers

Take 19.95 and subtract 17.85 from it to get 2.10. Divide 2.10 by 19.95 to get 0.105. Multiply that by 100 and you get 10.52. So it's 10% or maybe 11% if you're supposed to round. Hope this helps

Answer:

Find out the what percentage discount is seller offering you .

To prove

Formula

[tex]Discouunt\ percentage = \frac{Discount\times 100}{Marked\ price}[/tex]

Discount = Marked price - Selling price

As given

You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95 .

Here

Marked price = $19.95

Selling price = $17.85

Discount = 19.95 - 17.85

               = $2.1

Put in the formula

[tex]Discouunt\ percentage = \frac{2.1\times 100}{19.95}[/tex]

[tex]Discouunt\ percentage = \frac{210}{19.95}[/tex]

Discount percentage = 10.5% (Approx)

Therefore the discount is seller offering you is 10.5 % .

∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38 . What is the value of x? Enter your answer in the box.

Answers

Set the two measures equal to each other. Subtract 2x from both sides and subtract 8 from both sides. Leaving you with 6x=30. Then divide 30/6 and you get X=5

Answer:

x = 5

Step-by-step explanation:

We need to remember that vertical angles are opposite to each other when two lines cross. The vertical angles that result from two lines crossing have the same measure.

In this problem we have angle E which measures 8x + 8 and angle F which measure 2x + 38.

Since they are vertical angles, we know that they have the same measure and therefore we can equal them both and solve for x:

[tex]8x+8=2x+38\\8x-2x=38-8\\6x=30\\x=5[/tex]

Therefore, x = 5 (and ∠E = ∠F = 48)

Which expression can be used to change 75 kilometers per hours to meters per minute?

Answers

The fractions you use must be the correct conversion factors.

1 km = 1000 m, so you can have the fraction (1 km)/(1000 m) or the fraction (1000 m)//(1 km). You must choose the correct one for this problem.

1 hr = 60 min, so you can have the fraction (1 hr)/(60 min) or the fraction (60 min)/(1 hr). Again, you must choose the correct one for this problem.

The important thing is to choose the correct fraction from the choices.
How do you know which conversion fractions to use?
You look at the given units and the units you want.
You must pick the conversion fraction that will cancel out the units you DON'T want, leaving the units you want.

You have a speed in km/hr.
km is in the numerator. To cancel out km, you must pick the conversion fraction that km in the denominator.
hr is in the denominator. To cancel out hr, you must pick the fraction that has hr in the numerator.

[tex]75 \frac{km}{hr} \times \frac{1000~m}{1~km} \times \frac{1~hr}{60~min} [/tex]

Notice that km and km cancel out leaving m.

Find the measure of angle e.
A. 70°
B. 130°
C. 100°
D. 110°

Answers

Knowing about corresponding angles, we know that m∠d = 70°.

The sum of the measures of the angles d and g is equal to 180°. Or in other words, they are supplementary.

Knowing this, we can use algebra to build an equation and solve for g.

70° + m∠g = 180°
m∠g = 110°

And finally, using the knowledge of vertical lines, ∠g is complementary to ∠e.

So, m∠e is equal to 110°.

The measure of each interior angle of a regular polygon is 140 degrees, how many sides does the polygon have

Answers

using
[(n-2)180]÷n = 140
(n-2)180 = 140n
180n -360 = 140n
180n -140n = 360
40n = 360
n=360÷4 = 90 sides
Final answer:

The regular polygon with an interior angle of 140 degrees has 9 sides. This conclusion can be reached by using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides.

Explanation:

The number of sides in a regular polygon can be determined using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides. This formula comes from the fact that a polygon can be divided into (n-2) triangles, each of which has angles summing up to 180 degrees.

In this particular case, an interior angle of 140 degrees is given. So we will set up an equation: 140 = (n-2)*180/n. Solving for 'n', we get a value of 9.

Therefore, the regular polygon with an interior angle of 140 degrees has 9 sides.
