Your teacher gave you 2/3 a bag of candy, but she only gave your friend 1/8 of a bag.
How much more of the bag did your teacher give you than your friend?

Answers

Answer:

Step-by-step explanation:

We can convert the 2/3 bag of candy that we got to 16/24, by multiplying both the top and bottom by 8. Similarly, we multipy the 1/8 bag of candy that our friend got by 3 on the top and bottom to get 3/24.

We find the difference between these two:

(16/24) - (3/24) = (16-3)/24 = 13/24

So we get 13/24 more of the bag of candy than our friend did. (That's more than half!)

When demand for goods increases - Price will rise

When supply of goods increases - Prices will fall

Step-by-step explanation:

Supply and demand function works oppositely in economy. When there is huge demand for goods and supply is short then prices will rise. This is because supply is not sufficient to meet the demand and the market is not in equilibrium position.

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50. if an applicant is randomly selected, find the probability of a rating that is between 200 and 275.

Answers

Answer:

0.4332 = 43.32% probability of a rating that is between 200 and 275.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A bank's loan officer rates applicants for credit. the ratings are normally distributed with a mean of 200 and a standard deviation of 50

This means that [tex]\mu = 200, \sigma = 50[/tex].

Find the probability of a rating that is between 200 and 275.

This is the pvalue of Z when X = 275 subtracted by the pvalue of Z when X = 200. So

X = 275

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

[tex]Z = \frac{275 - 200}{50}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a pvalue of 0.9332

X = 200

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

[tex]Z = \frac{200 - 200}{50}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a pvalue of 0.5

0.9332 - 0.5 = 0.4332

0.4332 = 43.32% probability of a rating that is between 200 and 275.

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Answers

X=27 because all the angles inside a triangle add up to 180°. So you take 180 and subtract 63 and 90 from the to find out the last/missing angle.

Answer: 27°

Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.

To find the value of x, remember that the sum of the

measures of the angles in a triangle is 180°

So we can setup the equation 63 + 90 + x = 180.

Remember that a box indicates a 90° angle.

Now to solve for x, let's first simplify on the left side of the equation.

63 + 90 is 153 so we have 153 + x = 180.

Now to get x by itself, we subtract 153 from both sides of the equation.

On the left side of the equation, 153 - 153 cancels out and we have x

and on the right side of the equation, 180 - 153 is 27.

This means that the missing angle in the triangle is 27°.

Which line has a slope of 0?
y= -10

Answers

When the equation of any line reads "y = a number",

its graph will always be a horizontal line, meaning zero slope.

So the equation y = -10 has a slope of 0 which

What is kilograms ?

A unit of measurement used to describe mass or weight is the kilogram (kg). It is widely used all over the world to measure an object's weight because it is the International System of Units' (SI) fundamental unit of mass.

To convert grams to kilograms, you divide the number of grams by 1000 since there are 1000 grams in one kilogram.

So, 5,000 grams is equal to 5,000/1000 = 5 kilograms.

Therefore, the correct option is C. 5 kilograms.

y = 8x + 12


If x = -6, y = _____

If y = 13, x = _____

Answers

y = 8x + 12

if x = -6

y = 8(-6) + 12

y = -48 + 12

y = - 36


if y = 13

13 = 8x + 12

13-12 = 8x

8x = 1

x = ¹/₈ ≈ 0.125

Answer:

If x = -6, y = -36

If y = 13, x = [tex]\frac{1}{8}[/tex]

Step-by-step explanation:

There is one equation and are asked to find x and y if there is a certain value to substitute either x or y.

Let's start with x, we know that x = -6. Meaning that we need to subtitute x for -6. Do as followed :

y = 8(-6) + 12

y = -48 + 12

y = -36

Now do y, we know that y is 13. Meaning that we need to substitute y for 13. Do as followed :

8x + 12 = 13

We need to isolate x alone, so do as followed :

Subtract 12 from both sides to get 8x alone :

8x = 1

Divide 8 from both sides to get x alone :

x = 1/8

Would you use SSS or SAS to prove the triangles congruent? If there is not enough information to prove by SSS or SAS, then write “not enough information” and explain why.

Answers

Answer (d) :

These triangles are congruent under the SAS congruence criterion. We can prove it using the following steps :

Given :

In triangle 1 and 2 :

A side in triangle 1 and a side in triangle 2 are equal.Another side in triangle 1 and triangle 2 is equal. The angle between the equivalent sides is also equal.

Since the SAS congruence criterion says that two triangles are congruent if two of their sides and one included angle is equal and since these 2 triangles fulfill all of those rules, we can conclude that these triangles are congruent under the SAS congruence criterion.
