Rachael bought a snorkel and ear plugs for shallow diving. The snorkel cost $28.96, and the ear plugs cost $2.56. The sales tax of both items is 5%. How much did she pay in total?

Answers

Answer:

$33.10

Step-by-step explanation:

$28.96 + $2.56 = $31.52

$31.52 * .05 = $1.576 (round up) $1.58

$31.52 + $1.58 = $33.10

Answer:

Step-by-step explanation:

Total without sales tax

Snorkel  =         28.96

Ear Plugs            2.56

Total                  31.52

Sales tax = 5% of Total  = 5/100 *31.52

Sales tax = 1.58 Rounded.

You are interested in getting an investment portfolio started with any extra money you make from your part time job while also going to school. While flipping through the latest edition of Money magazine, you read an article that of a survey of magazine subscribers, 164 were randomly selected and analyzed. A 95% confidence interval was constructed for the proportion of all subscribers who made money in the previous year in their investments, which was ( 0.6904 , 0.8218 ). What is the correct interpretation of this confidence interval

Answers

Answer:

We are 95% confident that the proportion of all Money magazine subscribers that made money in the previous year from their investments is between 0.6904 and 0.8218

Step-by-step explanation:

The confidence interval gives a range of values for which a population proportion will fall based on a given level of confidence, in this case it is 95%. This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.

Circle = (x-h)^2 + (y-k)^2 = r^2

Center is (h,k) h = -5, k = 2
Radius is 4, r = 4

(x - -5)^2 + (y - 2)^2 = 4^2
(x + 5)^2 + (y - 2)^2 = 16

8) Solve the system of equations by substitution
y = x + 2
3x + y = 10

Answers

Answer:

(2, 4)

Step-by-step explanation:

y = x + 2

3x + y = 10

3x + (x + 2) = 10

4x + 2 = 10

4x = 8

x = 2

y = (2) + 2

y = 4

Step-by-step explanation:

3x + y = 10

substituting the value of y = x + 2

=>3x + x+2 = 10

=>4x= 10-2

=>4x= 8

=>x= 8/4

=>x= 2

And, y= 2+2 = 4

The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 121 and standard deviation of 16 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure

Answers

Answer:

Around 0.73% of adults in the USA have stage 2 high blood pressure

Step-by-step explanation:

Normal Probability Distribution:

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 121 and standard deviation of 16.

This means that [tex]\mu = 121, \sigma = 16[/tex]

Around what percentage of adults in the USA have stage 2 high blood pressure

The proportion is 1 subtracted by the p-value of Z when X = 160. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{160 - 121}{16}[/tex]

[tex]Z = 2.44[/tex]

[tex]Z = 2.44[/tex] has a p-value of 0.9927.

1 - 0.9927 = 0.0073

0.0073*100% = 0.73%

Around 0.73% of adults in the USA have stage 2 high blood pressure

Answer:

<ADB = 75 degrees

Step-by-step explanation:

We know, a straight line has an angle of 180 degrees.

A = (180-143) = 37 degrees.

A + C = (37 + 38) = 75 degrees.

The angles of a triangle will always add up to 180 degrees.

<ADC = (180-75) = 105 degrees.

So,

<ADB = (180-105) = 75 degrees.

To find how much she makes an hour you do 208 divided by 13 and get 16 so she gets $16 per hour.

Then to find how many hours it will be to make $144, you do 144 divided by 16 and get 9. So it will take her 9 hours to make $144

What is the solution to the system of equations below 2X minus Y equals 10 and Y equals -1/2 X plus 5

Answers

Answer:

x = 2 , y = 4.

(2,4)

Step-by-step explanation:

Simultaneous equation:

2x - y = 10    E1

y = [tex]-\frac{1}{2}x[/tex] + 5    E2

Substitute equation 2 into equation 1 for the y value.

2x -  [tex]-\frac{1}{2}x[/tex] + 5  = 10

2x -  [tex]-\frac{1}{2}x[/tex] = 5

2x +  [tex]\frac{1}{2}x[/tex] = 5

[tex]\frac{5}{2} x[/tex] = 5

x = 2

Substitute the x value  into  equation 2.

y = [tex]-\frac{1}{2}2[/tex] + 5
