Answer:

16/25 = 0.64

Step-by-step explanation:

18 rolls are ones, so 32 rolls are not ones.

The experimental probability is 32/50 = 16/25 = 0.64.

A school paid a total of $98.00 for 5 aluminum baseball bats and a total of $75 for 6 wooden baseball bats. How much more did EA

Luda [366]

Answer:

Each aluminium bat costs $7.1 more than wooden bat. PLS GIVE BRAINLIEST PLSSS

Step-by-step explanation:

Aluminium bats:

5 = $98

1 = 98/5

1= $19.6

Wooden bats:

6 = 75

1 = 75/6

1 = $12.5

$19.6 - $12.5

= $7.1

Write a linear equation. Explain it in number please! 20 points!!!

juin [17]

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

(-6,12) and (-5,14)

Now let us find the slope of the linear line:

$m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6} = 2$

So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

let us use the point (-6,12) and the slope of 2

$y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4$

So the linear line is y = 2x + 4.

Hope that helps!

The table shows the outputs, y, for different inputs, x:

Akimi4 [234]

A Yes as the x values are all different

B f(x) = 5x + 14

when x = 2 , f(x) = 5(2) + 14 = 24
x = 5, f(x) = 39,
Each value of f(x) is greater than corresponding ones in the function in A.
when x = 9 f(x) = 59 which is greater than for first function ( =12)

First function is a decreasing while f(x) is increasing

C f(x) = 64 = 5x + 14

5x = 64 - 14 = 50

x = 10

Find the slope of the line (-3,-2) (1,6)

nlexa [21]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, - 2) and (x₂, y₂ ) = (1, 6)

m = $\frac{6-(-2)}{1-(-3)}$ = $\frac{6+2}{1+3}$ = $\frac{8}{4}$ = 2

Solve the following new equation

mixer [17]

Answer:

<h3>x = 1.54 or x = - 4.54 to 2 decimal places</h3>

Step-by-step explanation:

x² + 3x - 7 = 0

Using the quadratic formula

a = 1 b = 3 c = - 7

$x = \frac{3 ± \sqrt{ {3}^{2} - 4(1)( - 7) } }{2(1)} \\ x = \frac{ - 3± \sqrt{9 + 28} }{2} \\ \\ x = \frac{ -3 ± \sqrt{37} }{2} \\ \\ x = \frac{ - 3 + \sqrt{37} }{2} \: \: \: \: \: or \: \: \: x = \frac{ - 3 - \sqrt{37} }{2} \\ \\ x = 1.54 \: \: \: or \: \: x = - 4.54$

Hope this helps you
