4x+5x = 90
9x = 90
x = 10

10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12

answer
<span>d) x = 10, y = 12</span>

Someone help me plz.

Answer:
20%

Explanation:
What we know:
- there are 25 cans in total
- 5 of them are root beer cans

Using this information, we can say that 5/25 cans are root beer cans. To find the percent, we change the fraction into a decimal and then multiply it by 100.

To change 5/25 into a decimal, we divide the numerator and denominator.
5/25=0.2

And we multiply the decimal by 100 to get the percent:
0.2*100=20

Therefore, 20% of Cam’s cans are root beer cans.

I hope this helps!

Answer:

$y = -\frac{1}{2}x + 2$

Step-by-step explanation:

Assume this is function is a straight line, consider the equation of the straight line: $y=mx + c$

To find the gradient of the equation, we use any two coordinates from the table. $(x_1,y_1) = (6,-1)\\(x_2,y_2) =(2,1)$

$m = \frac{y_1 - y_2}{x_1 - x_2}\\\\m = \frac{1-(-1)}{2-6}\\\\m=\frac{2}{-4} \\\\m=- \frac{1}{2}$

We substitute the value of m in the equation:

$y =mx+c\\y = - \frac{1}{2} x + c\\\\$

To find c, we use the leftover coordinates, (4,0) in the equation above:

$y = -\frac{1}{2}x+c\\\\0 = -\frac{1}{2} \times 4+c\\\\0 = -2 + c\\\\c=2\\\\$

Substitute this value of c in the equation to get the function:

$y = -\frac{1}{2}x + 2$

The number and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is shown below. This means, for instanc

Answer:

Shown below.

Step-by-step explanation:

The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:

Number: 0 1 2 3 4 5 6 7 8 11 12

Frequency: 5 16 20 14 3 5 4 4 2 1 1

The probability of an events, say <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

Compute the probabilities of 0 - 12 hurricanes each season as follows:

Number Frequency Probability

0 5 0.07

1 16 0.21

2 20 0.27

3 14 0.19

4 3 0.04

5 5 0.07

6 4 0.05

7 4 0.05

8 2 0.03

11 1 0.01

12 1 0.01

Total 75 1.00
