Answer: C. $67.50
Explanation:
1. Convert 25% into a decimal (0.25)
2. Multiply 90 by 0.25 to get the amount of money discounted. (90x0.25=22.5=$22.50)
3. Subtract 22.5 from 90 to get the sales price. (90-22.5=67.5=$67.50)

A sample with a sample proportion of 0.4 and which of the following sizes
will produce the widest 95% confidence interval when estimating the
population parameter?
A. 90
B. 60
C. 75
D. 120
The size 60 will produce the widest 95% confidence interval when estimating the population parameter.
What is confidence interval?'A confidence interval is the mean of your estimate plus and minus the variation in that estimate.'
According to the given problem,
IN a sample with n number of people surveyed with a probability of a success of [tex]\pi[/tex] and a confidence level of 1-α , we have the following confidence interval of proportions.
[tex]\pi[/tex] ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
In which, z is the z score that has a p value of 1 -(α/2)
The margin of error is:
M = z [tex]\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]
The higher the margin of error, the wider an interval is.
As the sample size increases, the margin of error decreases. If we want, the widest possible interval, we should select the smallest possible confidence interval.
Hence, we can conclude that 60 is the correct answer.

A women is twice as old as her daughter . twenty one years ago she was three times her daughter . What is the women's present age?
Answer:
84
Step-by-step explanation:
women=x
daughter=y.
x=2y.
x-21=3(y-21).
2y-21=3y-63.
42=y.
x=84.
Hope this helps plz hit the crown :D
Answer:
Daughter's present age = 42 years
Women's present age = 84 years
Step-by-step explanation:
Daughter's present age = x years
Women's present age = 2*x = 2x
21 years ago:
Daughter's age = x - 21
Women's age = 2x - 21
Women's age = 3*daughter'sage
2x - 21 = 3*(x - 21)
2x - 21 = 3x - 63 {Subtract '2x' from both sides}
- 21 = 3x - 2x - 63
-21 = x - 63 {Add 63 to both sides}
-21 +63 = x
42 = x
Daughter's present age = 42 years
Women's present age = 2*42 = 84 years

Annie measures 9 teaspoons of lemon juice for a recipe. There are approximately 4.9 milliliters in one teaspoon. How many milliliters of lemon juice did Annie measure?
Answer:
44.1 milliliters of lemon juice
Step-by-step explanation:
Number of teaspoons of lemon juice = 9 teaspoons
Amount of milliliters in one teaspoon = 4.9 milliliters
Amount of lemon juice = Number of teaspoons × Amount of milliliters
= 9 × 4.9
= 44.1 milliliters

Robert can mow 3 1/2 acres in 3/4 of an hour on his riding lawn mower.
At this rate, how many hours will it take him to mow 8 acres?
Answer:
It will take 1 5/7 hours
Step-by-step explanation:
3/4 of an hour is;
3/4 * 60 minutes = 45 minutes
3 1/2 acres is done in 45 minutes
8 acres will be done in x minutes
Thus, mathematically;
3 1/2 * x = 8 * 45
7x/2 = 360
7x = 2 * 360
7x = 720
x = 720/7 minutes
Let us convert this to hours
That will be;
720/7/60 = 720/(60 * 7) = 720/420 = 12/7
= 1 5/7 hours
Write the equation in slope-intercept form for the line that passes through (5, 4) and (6,-1).
SHOW YOUR WORK
Answer:
y = -5x + 29
Step-by-step explanation:
Slope-Intercept Form of the Line
Given a line of slope m and y-intercept b, the equation of the line can be written as:
y = mx + b
The slope can be calculated by using the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x1,y1) and (x2,y2) are the points through which the line passes.
We are given the points (5,4) and (6,-1), thus:
[tex]\displaystyle m=\frac{-1-4}{6-5}=\frac{-5}{1}=-5[/tex]
Now we use one of the points to find the value of b, for example (5,4):
4 = -5(5) + b
b = 25+4 = 29
Thus, the equation of the line is:
y = -5x + 29

The sum of Ken's, k, and Alan's, a, ages is 62. Ken is 31 years older than Alan.
Which of these systems of equations below best describes the ages of Ken and
Alan?
Answer:
k + a = 62
k = 31 + a
Step-by-step explanation:
Given that:
Sum of ken and Alan's age = 62
Ken is 31 years older than Alan
k + a = 62 - - - (1)
k = 31 + a - - - (2)
Hence, the system of equation which best describes the ages of Ken and Alan are:
k + a = 62
k = 31 + a

Given
[tex]log(9^2)[/tex]
Required
Select an equivalent expression

Given DEF : RST, find the scale factor.
PLEASE HELP!
9514 1404 393
Answer:
scale factor 3 : 4x = 12Step-by-step explanation:
To find the scale factor from ΔDEF to ΔRST, find a measure on ΔDEF and a corresponding measure on ΔRST, then write them in the form required for the scale factor.
Here, there are numbers on DE, RS, and ST. We see by the similarity statement ΔDEF ~ ΔRST that DE corresponds to RS, so the scale factor is ...
ΔDEF : ΔRST = DE : RS = 3 : 4 . . . scale factor
__
Using that scale factor, you can write a proportion to find the value of x.
3 : 4 = x : 16 ⇒ 3/4 = x/16
Multiplying the fraction equation by 16, we have ...
x = 16(3/4)
x = 12
