Find the value of x
A.9
B.18
C.45
D.90

Step-by-step explanation:

The total number of people mentioned in this problem is 15. 15 will be the denominator for the probability in fraction form. The sum of the # of people that include lifeguards and managers will be the numerator.

Therefore, the probability that the person picked is either a manager or a lifeguard is 10/15 [because there are 2 managers and 8 lifeguards; 2 + 8 =10].

Fraction form of probability: 10/15

Decimal form: 0.6 repeated

Percent form: about 66.67%

The probability that person is either a lifeguard or manager is 2/3.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

There are 2 managers 8 lifeguards 3 concession stand clerks and 2 maintenance people.

Total = 2 + 8 + 3 + 2 = 15

So, P(lifeguard) = 8/15, P(Manager) = 2/15.

Then, P ( lifeguard or Manager)

= 8/15 + 2/15

= 10/15

= 2/3.

Answer:

y= (5/2)x+2

Step-by-step explanation:

Answer:

$825

Step-by-step explanation:

Given that :

Weekly earning = $600 plus 3% of sales over $6500

If weekly sales = $14000

How much will Robin earn

Robin's earning will be:

Flat weekly pay + 3% of amount over 6500

$600 + 3%(weekly sales - 6500)

$600 + 0.03(14000 - 6500)

$600 + 0.03(7500)

$600 + $225

= $825

Answer:

57°

Step-by-step explanation:

The ladder will be the hypotenuse while the 4.2 meters will be a leg.

We want the angle between the ground & the ladder. Therefore, 4.2 is on the opposite side of the angle.

sin(theta) = opposite/hypotenuse

sin(theta) = 4.2/5

theta = arcsin(4.2/5)

theta = 57°

Step-by-step explanation:

8/2 simplifies to 4

4 is a whole number

a whole number is an integer

an integer is rational

it is not irrational since it can be written as a fraction

Step-by-step explanation:

In 1/10 of 1hr = 1/2 mile

10*(1/10) of 1hr = 10(1/2) mile

(10/10) of 1hr = (10/2) mile

1 of 1hr = 5mile

It says, he can run 5 miles in 1 hour

Answer:

Pretty much, it's just 46 times 7. So, you can do 322 jumping jacks in 7 minutes.

Please mark me as Brainliest, I need it to move onto the next level. =D

Analysing the Question:

We are given the function:

f(x) = 46x

where x is the number of minutes and f(x) is the number of jumping jacks in the given number of minutes

Number of jumping jacks in 7 minutes:

replacing x with number of minutes (i.e, 7). We get:

f(7) = 46*7

f(7) = 322 jumping jacks

Answer:

Area of rectangle = (l×b)

=84 metre²

Perimeter of rectangle= 2×(l+b)

=2×(14+6)

=2×20

40 metre/cm {as it is not given}

Step-by-step explanation:

Hope this helps you

Crown me as brainliest

Answer:

Step-by-step explanation:

To find the area you need to multiply the two length and height.

14 x 6

This would equal 84.

For the perimeter you add all the sides. Since there are four sides to a rectangle and a square, you add 2 of the corresponding sides to the equation.

14+14+6+6

Or

2(14+6)

Or

2(14) + 2(6)

Which equals 40.

Answer:

y = -2/3x +4 --> y = mx+b form

Step-by-step explanation:

-3x-2y = -8 --> add 3x to both side

-2y = 3x-8 --> divide by -2 on both side

y = -2/3x +4 --> y = mx+b form

the y intercept is 4 and the slope is -2/3, down 2, right 3.

therefore, the graph would contain a y intercept point of (0,4) and then from there u would start plotting down 2, going right 3 unit or up 2 and left 3 units. Then when u plotted at least 2/3/4 points, use a straightedge to draw the line.

Answer:

45

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

3x+9y = 27.9

To find the x intercept , let y=0

3x +0 = 27.9

Divide each side by 3

3x/3 = 27.9/3

x = 9.3

The x intercept is 9.3

To find the y intercept , let x=0

0+9y = 27.9

Divide each side by p

9y/9= 27.9/9

y = 3.1

The y intercept is 3.1

Answer:

28 weeks

Step-by-step explanation:

It says that $42 was 1/3 of her total. So you multiply $42 by 3 and you get $126. You now divide $126 by her weekly allowance, $4.5, and the answer is 28.

1. $42 x 3 = $126

2. $126/$4.5 = 28

3. The answer is Sharon has been saving her allowance for 28 weeks.

Hope this helps!

-Jerc

Answer:

She has been saving her money up for 28 weeks.

Step-by-step explanation:

1. If 42 is 1/3 of her money, then you would multiply 42 by 3 to get the full 3/3 so: 42•3=126

2. Next, you would divide $126 by $4.50 because that is the total amount of money divided by how much she saved up each week, so: 126/4.5=28 and that gives us the answer which is 28.
