It’s 0.8 because 24/30 is equal to 0.8.
Here’s how:
Divide 24 by 30. Your answer is 0.8. :)

Answer:

0.8

Step-by-step explanation:

just do 24/30 which is just divison so 24÷30 which gives you 4/5 or 0.8. however you may need to use a calculator to help :)

A high school basketball coach is selecting his team. The minimum and maximum height requirements are as follows:
daser333 [38]

Answer:

B. About 2% of the boys are eligible to be a small forward on the team

Step-by-step explanation:

Recall : 1 feets = 12 inches

Point guard = 6’2" – 6’6" tall = 74 - 78 inches

Mean = 70 ; Standard deviation = 4

Z = (x - mean) / standard

P(x < 74) = (74 - 70) / 4 = 1

P(x < 78) = (78 - 70) / 4 = 2

0.97725 - 0.84134 = 0.13591

Small forward : 6'6" = 78 inches

P(x ≥ 78) = (78 - 70) / 4 = 2

P(z ≥ 2) = 0.02275 = 2.275% about 2%

Centre : 6'8" = 80

P(x ≥ 80) = (80 - 70) / 4 = 2.5

P(z ≥ 2.5) = 0.0062097 = 0.62%

How do you factor: x^2-4x+2xy-8y?
hoa [83]

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

(x^{2}−4x)+2xy−8y

Factor out the greatest common factor (GCF) from each group.

x(x−4)+2y(x−4)

Factor the polynomial by factoring out the greatest common factor,  x−4.

(x−4)(x+2y)

I believe this is correct. Good luck.

Please help to prove parallelogram.​
tino4ka555 [31]

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.

<h3>What is a mathematical proof?</h3>

Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.

<h3>What is the proof that WV = VR?</h3>

  • Note that SR ║ QT;

Reason: This is given. The image is a parallelogram.

  • Hence, ∠PSR  = ∠WVP
    Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
  • Therefore: ΔSVR ≅ PVW
  • Reason: They are formed by two parallel lines crossing each other.

Therefore if  ΔSVR ≅ PVW;

Then WV = VR.

QED.

The graph of the function g(x) = x2 + 3x - 4 is shifted 5 units to the left. Plot the zeros of the new function on the provided
Colt1911 [192]
<span>g(x) = x^2 + 3x - 4   (please be sure to use " ^ " to denote exponentiation).

This function factors into g(x) = (x+4)(x-1), and so the zeros are -4 and +1.

If we shift this graph 5 units to the left, we get h(x) = (x+5)^2 + 3(x+5) - 4.

The new zeros will be -4-5    and    1-5,    or  -9 and -4.
