Answer:45

Step-by-step explanation:

There are 3 even numbers out of A total of 8 numbers.

Each spin would have a 3/8 chance of landing in an even number.

Multiply the chance of landing on even by number of spins:

120 x 3/8 = 360/8 = 45

The answer would be 45 times.

) A basketball court is 94 feet by 50 feet. Eight fans can
tatyana61 [14]

Answer:

<h2>4178kids</h2>

Step-by-step explanation:

Area of the basket ball court = Length * Breadth (since it is rectangular in nature)

Area of the basket ball court = 94 feet * 50 feet

Area of the basket ball court = 4700ft²

Area of the space covered by 8 kids = 3ft * 3ft = 9ft²

To know the number of kids that would fit the entire floor, we will use the expression;

Number of kids in the floor = 8*Area of the basket ball court /Area of the space covered by 8 kids = 8*4700/9

= 8*4700/9

= 8*522.22

≈ 4,178 kids

<em>Hence approximately 4,178 kids can fit side by side  over the entire floor</em>

Let g(x) = x² - 3 and h(x) = 2x + 5. Find g(h(x)).
Arisa [49]

Answer: 4x^2+20x+22\\\\

========================================

Work Shown:

g(x) = x^2 - 3\\\\g(h(x)) = (h(x))^2 - 3\\\\g(h(x)) = (2x+5)^2 - 3\\\\g(h(x)) = (2x+5)(2x+5) - 3\\\\g(h(x)) = 4x^2+10x+10x+25 - 3\\\\g(h(x)) = 4x^2+20x+25 - 3\\\\g(h(x)) = 4x^2+20x+22\\\\

Explanation: I replaced every x with h(x) in step 2. In step 3, I replaced h(x) with 2x+5 just on the right hand side only. From there, expand and simplify.

Graph a line with a slope of -3 that contains the point 4,-2
JulsSmile [24]

Answer:

y=-3x+10

Step-by-step explanation:

Use point-slope form first.

y-y1=m(x-x1)

Plug the numbers into that.

y+2=-3(x-4)

Distribute and simplify to convert it to y=mx+b

y+2=-3x+12

y=-3x+10
