Answer:
Removing pennies and dimes from the bag
Step-by-step explanation:
From the beginning, we have a 1 in 3 chance of drawing a quarter. If we were to add dimes and/or pennies to the bag, this would make us more likely to draw a dime or a penny, and less likely to draw a quarter. Proportionally, we want the most quarters in the bag to get the highest probability of drawing a quarter from the bag.

PLSSSSSS HELP!!!! TIME LIMITEDDD!!!!!! Joan wants to draw a picture that includes a pair of complementary angles. Joan wants one of the angles to be 18° more than the other angle. Select True or False for each statement about the angles.
The smaller angle is 18°.
The smaller angle is 36°.
The larger angle is 54°.
The larger angle is 72°.
Answer:
True: The smaller angle is 36°; The larger angle is 54°
False: The smaller angle is 18°. The larger angle is 72°
If you create an equation using this scenario, it would be (18+x)+x=90, because complementary angles sum up to 90°. Add the like terms to get 18+2x=90. Subtract 18 on both sides to get 72. Divide 2 on both sides to result with x=36. Subtract 90 with 36 to get 54. The smaller angle is 36° and the larger angle is 54°.
Which inequality represents the number line below?
x = 3
x < 3
x > 3

Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

The variable, c, represents The cost of each song is part of a total, so the operation is The correct equation to solve this problem is
Answer:
For this case we can see the table as a set of ordered pairs.
We then have the following ordered pairs:
(-6, -7)
(-1,1)

Required
Solve:
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2[/tex]
Apply law of indices
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{4^3} * \frac{2^2}{3^2}[/tex]
Express 4 as 2^2
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{(2^2)^3} * \frac{2^2}{3^2}[/tex]
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{2^6} * \frac{2^2}{3^2}[/tex]
Express as a singe fraction
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3*2^2}{2^6*3^2}[/tex]
Apply law of indices:
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^{3-2}}{2^{6-2}}[/tex]
[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^1}{2^4}[/tex]

Scores turned in by an amateur golfer at the Bonita Fairways Golf Course in Bonita Springs, Florida, during and are as follows: 2018 Season: 74 78 79 77 75 73 75 77 2019 Season: 71 70 75 77 85 80 71 79 a. Use the mean (to the nearest whole number) and standard deviation (to decimals) to evaluate the golfer's performance over the two-year period. Mean Standard deviation Mean Standard deviation b. What is the primary difference in performance between and
Answer:
Step-by-step explanation:
The mean for 2018 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2018 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{30}{7} }[/tex]
s = 2.07
The mean and standard deviation for the year 2018 scores is:
2018
Mean 76
Standard deviation 2.07
The mean for 2019 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2019 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{194}{7} }[/tex]
s = 5.26
The mean and standard deviation for the year 2019 scores is:
2019
Mean 76
Standard deviation 5.26
Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.
Thus, the variation in scores was higher in 2019.
