As a result of inflation, the purchasing power of a fixed quantity of money decreases by 5% every year. If a certain quantity of money can buy 940 frozen dinners this year, how many frozen dinners can it buy in 16 years?
There would be 413 frozen dinners in the next 16 years.
How to solve an exponential function?Let y represent the amount of frozen dinners after x years.
If a certain quantity of money can buy 940 frozen dinners this year, and it decreases by 5% every year, hence:
y = 940(0.95)ˣ
In 16 years:
y = 940(0.95)¹⁶
y = 413.71
There would be 413 frozen dinners in the next 16 years.

Find the equation in slope-intercept form of the line satisfying the conditions. m = 6, passes through (2, -8)
y=6x-20
Solution:First, let's write the equation in point-slope form:y-y1=m(x-x1)y-(-8)=6(x-2)y+8=6(x-2Convert to slope-intercept:y+8=6x-12y=6x-12-8y=6x-20Hope it helps.
Do comment if you have any query.
Answer:
y = m x + b is the standard form for a straight line
you have
y = 6 x + b if m = 6
Now when x = 2, y = -8 this is given
- 8 = 6 * 2 + b substituting given values
b = -8 - 12 = -20
y = 6 x -20 is the equation requested
Check;
-8 = 6 * 2 - 20
12 = 12 so this agrees

Factor -2x^3 + 57x^2 - 196x
Answer: -x(x-4)(2x-49)
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
Answer:
-x (x-4) (2x-49)
Step-by-step explanation:
take out -x
you then have
2x^2-57x+196
then factor the remaining
multiply number next to x^2 which is a with 196 which is c
(-57 is b)
multiply 2 with 196 which = 392
then find out what 2 factors of 392 add up to -57
they are -8 and -49

Write the equation of a line that passes through the point (-5,-4) and has a slope of 1/5
Typically, linear equations are written in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = y-intercept (the value of y when the line crosses the y-axis)To find the equation of a line given a point and the slope:
Plug the slope into y=mx+b as mPlug the point into y=mx+b as (x,y)Solve for bPlug b back into y=mx+b along with mSolving the Question
We're given:
[tex]m=\dfrac{1}{5}[/tex]Passes through (-5,-4)[tex]y=mx+b[/tex]
⇒ Plug in the slope, [tex]\dfrac{1}{5}[/tex]:

(2, -4)
Step-by-step explanation:
Answer:
(2, -4)
Step-by-step explanation:
The solution to a system of equations is always going to be the point(s) where they intersect. To solve, use substitution and find each variable, x and y. Our final answer will be a set of coordinates (x, y). To plot this system, see the help image attached.
y = -x - 2
2x - y = 8
Substitute y to find x
2x - (-x - 2) = 8
2x + x + 2 = 8
3x = 6
x = 2
Substitute x to find y
y = -(2) - 2
y = -2 - 2
y = -4
Solution: (2, -4)

Which of the following statements are TRUE about the normal distribution? Check all that apply.
a. A z-score is the number of standard deviations a specific data value is from the mean of the distribution.
b. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean.
c. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean.
d. The mean corresponds to the z-score of 1.
e. The area to the left of a z-score plus the area to the right of that same z-score will always equal 1.
Using the normal distribution, it is found that statements a, b, c and e are correct.
Normal Probability DistributionThe 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.What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Hence, only statement D is false, as the mean corresponds to z-score of 0.

The centroid O cuts every median in the ratio 2:1. The distance between a vertex and the centroid is twice the distance between the centroid and the midpoint of the opposite side.

What would be the slope intercept form for the inequality 3x-2y>5?
Answer:
y<3/2x-5/2
Step-by-step explanation:
You just have to know how to get y on one side and the rest of the problem on the other.
First you would subtract 3x from both sides, which leaves you with -2y>5-3x.
Lastly you would divide both sides by -2.
To get the final answer of y<3/2x-5/2

The probability that a meal at a restaurant is overcooked is 10%. Estimate the probability that exactly 1 of the next 2 meals is overcooked.
Answer:
The probability that exactly 1 of the next 2 meals is overcooked = 3.34%
Step-by-step explanation:
The probability that a meal at a restaurant is overcooked is 10%
The probability that exactly 1 of the next 2 meals is overcooked = out of 3 meals 1 meal is overcooked of 10%
= 1 × 3 × 10%
= 10 × 3 %
= 3.34 %
Answer: 18.1%

In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving AEC ≅ DEB, given that CA is parallel to DB and E is the midpoint of AD. Submit the entire proof to your instructor.
Given:
CA || DB
E is the midpoint of AD
Prove:
AEC ≅ DEB
A two column proof for ΔAEC ≅ ΔDEB is as shown below.
What are congruent triangles?"Two triangles are congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure."
What are interior angles?"These angles formed on the inside of two straight lines when crossed by a transversal."
What is midpoint?"It is point which divides a line segment into two equal parts."
What is AAS postulate of triangle congruence?"AAS (Angle Angle Side) theorem states that in the two triangles, if two angles and one side of a triangle are congruent to two angles and one side of a second triangle, then the two triangles are congruent."
For given question,
Given that CA is parallel to DB and E is the midpoint of AD.
CA is parallel to DB
CB is transversal.
∠ACB and ∠CBD are alternate interior angles.
We know that when a transversal intersects a parallel line then alternate interior angles formed are congruent.
So, ∠ACB ≅ ∠CBD ................(i)
Similarly for CA || DB and AD is transversal.
∠CAD ≅ ∠ADB ..................(ii)
Also, E is the midpoint of AD.
By definition of midpoint,
⇒ AE = ED ..................(iii)
From (i), (ii) and (iii),
By AAS postulate of triangle congruence,
ΔAEC ≅ ΔDEB
Therefore, a two column proof for ΔAEC ≅ ΔDEB is as shown below.

Annabelle uses models to compare two decimal numbers. She says 0.24 is greater than 0.4 because 24 > 4.
A square partitioned into one hundred equal parts with twenty four parts shaded. To the right is a square partitioned into ten equal parts with four parts shaded.
Which of these explains Annabelle's mistake?
A. Annabelle incorrectly shaded the models. She should shade six more tenths.
B. Annabelle incorrectly counted the number of shaded parts in the models. She should compare 3 shaded parts to 4 shaded parts.
C. Annabelle incorrectly compared hundredths to tenths. She should compare 24 hundredths to 40 hundredths.
D. Annabelle incorrectly compared tenths. She should compare 4 hundredths to 4 hundredths.
Answer:
C
Step-by-step explanation:
0.24 is the same as 24 hundredths.
0.4 is the same as 4 tenths or 40 hundredths.
You volunteer to help drive children at a charity event to the zoo, but you can fit only 6 of the 15 children present in your van How many different groups of 6 children can you drive?
However if you are asking how many different combinations, there can be 5005 different combinations.
Answer:
2 different groups of 6 children.
Step-by-step explanation:
There are 15 children you need to bring. You can fit 6 children in each van.
One van : 6 children
Two vans : 12 children
Three vans : 18 children
If you take two vans, that will take 12 children. But you need to fit 15.
If you take three vans, that will take 18 children. This is more than enough.
15 children - 6 = 9 children
Thats one group with 9 children left to take
9 children - 6 = 3 children
Thats two groups with 3 children left to take
3 children - 6 = -3.
This doesn't work. In this case, there will be 3 more empty seats in the last group.
Since the question asks how many groups of 6 children you can drive. It would be two. Becuase there are 2 groups of 6 and one of 3.
