b) 2
C) 25
d) 3

Answers

Answer:

d) 3

Step-by-step explanation:

1.5= 1 hour and 30 mins

+ 30 mins = 2 hours

.75 hours = 45 mins

+ 15 mins = 1 hour

2 hours + 1 hour = 3 hours

The solution is, d) 3 hours of activity do you have planned.

What is addition?

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

given that, You have planned activities of 30 minutes, 15 minutes, 1.5 hours, and .75 hours.

now, we have,

1.5= 1 hour and 30 mins

with that add,

+ 30 mins = 2 hours

again, we know,

.75 hours = 45 mins

adding with that,

+ 15 mins = 1 hour

finally, adding we get,

2 hours + 1 hour = 3 hours

Hence, The solution is, d) 3 hours of activity do you have planned.

Gita is a single taxpayer earning $50,000 in wages this year.


In addition, she received $750 in nonqualified dividends and $2,500 in capital gains from a stock she held for 10 months.

Use the following tables to complete the statement.


Single Taxpayers: Income Brackets

Tax Rate Income Bracket

10% 0 to 9,525

12% 9,526 to 38,700

22% 38,701 to 82,500

24% 82,501 to 157,500

32% 157,501 to 200,000

35% 200,001 to 500,000

37% > 500,000

Single Taxpayers: Qualified Dividends and Long-Term Capital Gains

Gita must pay $ (blank) in taxes on her investment income.

Answers

Answer:

Gita must pay $ 487.50   in taxes on her investment income

Step-by-step explanation:

Without mincing words Gita falls into income tax brackets of $38,601 and $425,800 from qualified dividends and long-term capital gains perspective since he had wages of $50,000 and other income totaling  $3,250($2500+$750)

As a result,the taxes on her investment income of $3,250 is 15% of the investment income.

investment income taxes=$3,250*15%=$ 487.50

The discriminant of the equation x2 + x - 30 = 0 is?

The solution(s) of the equation x +x-30 = 0 is/are?

Answers

Answer:

discriminant: 11solutions: -6, +5

Step-by-step explanation:

Comparing your equation to the standard form, we can find the values necessary to compute the discriminant:

  x^2 +x -30 = 0

  ax^2 +bx +c = 0

So, we have ... a = 1, b = 1, c = -30

The discriminant is defined as ...

  d = √(b² -4ac) = √(1² -4(1)(-30)) = √121

  d = 11

The solutions are ...

  x = (-b ± d)/(2a) = (-1 ±11)/2

  x = {-6, +5}

Alex used a regression calculator to find the equation of the trend line y = a x + b for the data in the table. He rounded the values for a and b on his calculator as shown below.

a = 1.7
b = 6.2

Which trend line compares the data in the table?

s = 1.7 f + 6.2
s = 6.2 f + 1.7
f = 1.7 s + 6.2
f = 6.2 s + 1.7

Answers

Answer:

The regression equation of the data will be:

[tex]s=6.2f+1.7[/tex]

Step-by-step explanation:

A simple linear regression equation is used to estimate the value of the dependent variable based upon the independent variable.

The general form of a simple linear regression equation is:

[tex]y=a+bx[/tex]

Here,

y = dependent variable

x = independent variable

a = intercept

b = slope

The data is provided for the number of free throws a player makes in a basketball game and the number of points the player scores in the game.

The free throw in a basketball game implies that for every throw shot made the player receives point.

This implies that the points scored are based upon the number of free throws made by a player.

So, the dependent variable is the number of points scored and the independent variable is the number of free throws a player makes.

Then the regression equation of the data will be:

[tex]s=6.2f+1.7[/tex]

y = 1.7x + 6.2

Tasty Things Bakery recently sold 20 desserts, including 8 brownies. Considering this data, how many of the next 5 desserts sold should you expect to be brownies?

Answers

Answer:

About 2 of their next 5 deserts sold would be brownies.

Let's represent this by fractions. If 8 out of the 20 desserts they sold were brownies, that would make the fraction 8/20 represent how many brownies were sold.

Now if you reduce this fraction, you get 2/5, which tells about how many brownies will be sold in the next 5 brownies judging by the other data.

Researchers surveyed 1,000 randomly selected adults in the U.S. A statistically significant, strong positive correlation was found between income level and the number of containers of recycling they typically collect in a week.
1. Please select the best interpretation of this result.
Group of answer choices:
O This result indicates that earning more money influences people to recycle more than people who earn less money.
O We can not conclude whether earning more money causes more recycling among U.S. adults because this type of design does not allow us to infer causation.
O This sample is too small to draw any conclusions about the relationship between income level and amount of recycling for adults in the U.S.

Answers

Answer:

Null hypothesis: [tex]\rho =0[/tex]

Alternative hypothesis: [tex]\rho \neq 0[/tex]

The statistic to check the hypothesis is given by:

[tex]t=\frac{r \sqrt{n-2}}{\sqrt{1-r^2}}[/tex]

And is distributed with n-2 degreed of freedom. df=n-2[/tex]

For this case we got a significant result that means that the real correlation coefficient is different from 0 . And for this case the best interpretation would be:

This result indicates that earning more money influences people to recycle more than people who earn less money

Step-by-step explanation:

The correlation coeffcient is given by this formula:

[tex]r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}[/tex]  

For this case we know that this value of r is positive and represent a string correlation between income level and the number of containers of recycling

In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:

Null hypothesis: [tex]\rho =0[/tex]

Alternative hypothesis: [tex]\rho \neq 0[/tex]

The statistic to check the hypothesis is given by:

[tex]t=\frac{r \sqrt{n-2}}{\sqrt{1-r^2}}[/tex]

And is distributed with n-2 degreed of freedom. df=n-2[/tex]

For this case we got a significant result that means that the real correlation coefficient is different from 0 . And for this case the best interpretation would be:

This result indicates that earning more money influences people to recycle more than people who earn less money

When a number is increased by 28%, the result is 47. What is the original number to the nearest tenth?

Answers

Answer:

The original number was 36.7.

Step-by-step explanation:

Multipliers:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

In this question:

The original value is x.

Increased by 28%, so we have that 1 + (28/100) = 1.28x. Equals 47. We have to find x.

1.28x = 47

x = 47/1.28

x = 36.7

The original number was 36.7.
