Complete question :

Brianna asked 45 students if they would vote for her to be student council president. She used her calculator to compare the number of students who said yes with the total number of students. Her calculator showed the result as 0.6222...

1. Write this number as a fraction (Steps)

2. How many students said they would vote for Brianna?

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Total number of students = 45

Proportion of those who said yes to the total number of students = 0.62222...

1.) writing 0.622222... as a decimal

0.62222 / 1

Multiply numerator and denominatior by 100000 to get rid of the decimal

62222/100000

= 31111 / 50000

Let number who said yes = y

Then,

y / 45 = 31111/50000

50000y = 1399995

y = 1399995 / 50000

y = 27.999

y = 28

Answer:

8 minutes.

Step-by-step explanation:

Using ' t ' for the number of minutes.

" 59 > 19 + 5t "

→ Solve for t...

= 59 > 19 + 5t

= 59 - 19 > 5x

= 40 > 5t

= 40/5 > t

= 8 > t

Thus, It will take 8 minutes to add 59 litres of water.

19+5t>59

5t>59-19

5t>40

t>8

Complete Question

A baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each.

The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can

purchase. Which statement about the number of new baseballs that can be purchased is true?

A. The team can purchase 204 new baseballs.

B. The minimum number of new baseballs that can be purchased is 185.

C. The maximum number of new baseballs that can be purchased is 185.

D. The team can purchase 185 new baseballs, but this number is neither the

maximum nor the minimum.

Answer:

D. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

Step-by-step explanation:

The first step would be to solve the given equation:

185 + 4b ≤ 1000

4b ≤ 1000 - 185

4b ≤ 815

Divide both sides by 4

b ≤ 203.75

The maximum amount of baseballs the team can buy is 203. This means that they can buy 203 or less than that amount.

Of all the options give, option D is the correct option because the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

The maximum number of ball they can buy is 203 balls and the minimum is zero.

Using the normal distribution and the central limit theorem, it is found that there is a 0.2119 = 21.19% probability that more than 77​% of the sample have a​ driver's license.

In a normal distribution 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]

In this problem, we have that:

The conditions are verified because:

np = 300 x 0.75 = 225 > 10.

n(1-p) = 300 x 0.25 = 75 > 10.

The mean and the standard error are given by:

[tex]\mu = p = 0.75[/tex]

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.75(0.25)}{300}} = 0.025[/tex]

The probability that more than 77​% of the sample have a​ driver's license is one subtracted by the p-value of Z when X = 0.77, hence:

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

By the Central Limit Theorem

[tex]Z = \frac{0.77 - 0.75}{0.025}[/tex]

Z = 0.8

Z = 0.8 has a p-value of 0.7881.

1 - 0.7881 = 0.2119.

0.2119 = 21.19% probability that more than 77​% of the sample have a​ driver's license.

Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle.

Using proportions, it is found that the change in 2007 was about 5.07 times greater than the change is 2000.

A proportion is a fraction of a total amount. Using it, to find how many times a measure a is greater than a measure b, we divide a by b.

In this problem:

Hence:

$0.71/$0.14 = 5.07.

The change in 2007 was about 5.07 times greater than the change is 2000.

Solution:

We know that:

[tex]Original \ price = \$11[/tex]

[tex]Sale \ price = \$9.25[/tex]

Simplify the equation to find the percent off:

Step-by-step explanation:

Let's say the width is x

Of the length is 5 times the width, then the length is 5x

Area = length * width

405 = x * 5x

405 = 5x^2

405/5 = 5x^2/5

81 = x^2

Take the square root of both sides

2/[81 = 2/[x^2

9 = x = width

9 × 5 = 45 = length

Perimeter = 2 × length + 2 × width

2 × 45 + 2 × 9

90 + 18 = 108

Step-by-step explanation:

The fishing boat traveled for 14 hours before the cruise ship caught up.

We have,

Let's assume that the fishing boat traveled for x hours before the cruise ship caught up.

In that time, the fishing boat covered a distance of 10x km.

During the same 10 hours, the cruise ship traveled 14 x 10 = 140 km.

Since both the fishing boat and the cruise ship covered the same distance, we can write:

10x = 140

Solving for x, we get:

x = 14

Therefore,

The fishing boat traveled for 14 hours before the cruise ship caught up.
