Answer: x = -7
Step-by-step explanation: use the slope formula and slope intercept form y = mx + b to find the equation
A sperm cell differs, as it only contains half of the 46 chromosomes a human cell usually has.
Answer:
a) 
D. 9.74
b) 
B. 74
Step-by-step explanation:
Part a
We have the following dataset given:
69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83
We can begin calculating the sample mean with the following formula:

And replacing we got:

Now we can calculate the sample deviation with the following formula:

And after replace we got:

Part b
For this case we need to sort the value on increasing way:
[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93
And the median would be the value in the position 13 and we got:

3/4 * h = 2 1/4
3/4* h * 4/3 = 9/4 * 4/3
h = 3
Answer:
x=18
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8(1.5x−6)=2x−0.5(24−16x)
(8)(1.5x)+(8)(−6)=2x+(−0.5)(24)+(−0.5)(−16x)(Distribute)
12x+−48=2x+−12+8x
12x−48=(2x+8x)+(−12)(Combine Like Terms)
12x−48=10x+−12
12x−48=10x−12
Step 2: Subtract 10x from both sides.
12x−48−10x=10x−12−10x
2x−48=−12
Step 3: Add 48 to both sides.
2x−48+48=−12+48
2x=36
Step 4: Divide both sides by 2.
2x/2=36/2
x=18
Answer:
x=18
