Answer: 18b-2+2=214 +2
Step-by-step explanation:Add 2 both sides of the equation
Answer:
b = 12; he bought 12 boxes.
Step-by-step explanation:
18b - 2 = 214 (subtract 2 on both sides)
18b = 216 ( divide 18 on both sides to get 'b' alone)
b = 12
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.
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.

solve the inequality 2(n+3) - 4 < 6. then graph the solution.
Please help ??
Answer:
n < 2
Step-by-step explanation:
Answer: Look at the explanation please.
Step-by-step explanation:
The first thing you would do is distribute the 2 to the n and the 3.
You will then get 2n+6-4<6
Next, you will have to subtract 6-4 and you will get 2
You will the have 2n+2<6
Subtract 2 from 2 to get 0 and from 6 to get 4.
Your left with 2n<4
Then, divide 2 from 2n and 2 from 4
Last, your answer will be n<2.
Graphing
Your graph would look like (from what I see in my book)
You have seven tick marks and in the middle will be 0.
From the left of 0 should have negative 1, 2, and 3
From the right of 0 would be positive 1, 2, and 3
On the top of 2 would be a open circle and an arrow going to the left.
Hope this helps :)

Sarah has just received a box of chocolates from a dear friend. Her friend tells her that inside the box there are two kinds of chocolate: milk and dark. There are more milk chocolates than dark chocolates. Subtracting the number of dark chocolates from the number of milk chocolates gives 5 as an answer. The number of milk chocolates is twice that of dark chocolates. How many dark chocolates are there?
Which line has a slope of 0?
y= -10
2y + 6x = 0
x= – 5
y=x+5
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
means its a flat or horizontal line.
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.
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.

(Please I will mark BRAINLIEST, not lie)Use this equation to solve for the missing variable:
y = 8x + 12
If x = -6, y = _____
If y = 13, x = _____
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

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

3. How many kilograms are equal to
5,000 grams?
A 500 kilograms
B 50 kilograms
C 5 kilograms
D 0.5 kilogram
Answer:
C.) 5 kilograms
Step-by-step explanation:
1000 grams = 1 kilogram
To convert grams to kilograms we divide by 1000
5000g divided by 1000 kg = 5kg
May I Please Have Brainliest I'm trying to achieve a new rank
5,000 grams is equal to 5,000/1000 = 5 kilograms. The correct option is C
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.

Evaluate
4w^2+3
for w = 5.
Answer:
103
Step-by-step explanation:
first you would need to plug in the 5 to the equation, this would get you 4(5)^2+3 and then you would simplify the exponent which would get you 4(25)+3 then you would multiply 4x25 which would give you 100 finally you would add the 3 giving you the final produt of 103.
Answer:
103
Step-by-step explanation:
You would sub in 5 for w
4(5) ^2 + 3
you square the 5 and get 25 then multiply by 4 which gets your 100 and then add the 3 which gets the Final Answer as 103

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?
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!)

Answer:
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.
