The mean of the standard normal graph shown is the middle point about which the graph is symmetric.

Hence, mean is 75.

Also, given that standard deviation is 6.

What is 1 standard deviation from the "mean" mean?

75+6=81 and 75-6=69

So a value within 69 and 81 would be called within 1 standard deviation of the mean.

So, calculating 2 standard deviation from the mean as:

75+6+6=87 and 75-6-6=63

So a value within 63 and 87 would be called within 2 standard deviation of the mean.

84 falls in this category, so we can say answer choice B is correct.

A person borrows $50000 loan from bank at a rate of 10% for 5 years compounded yearly.

Hatshy [7]

<h3>Given:</h3>

P= $50,000
R= 10%
T= 5 years

P= Principal amount
R= Rate of interest
T= Time period

<h3>Solution:</h3>

$\large\boxed{Formula: A= P(1+ \frac{R}{100}{)}^{T}}$

Let's substitute according to the formula.

$A= 50000(1+ \frac{10}{100}{)}^{5}$

A= $80525.5

Now, we can find the interest paid

$\large\boxed{I= A-P}$

We'll have to deduct the total amount from the principal amount.

Let's substitute according to the formula.

$I= 80525.5-50000$

I= $30525.5

Hence, the total amount paid after 5 years is $80525.5 and $30525.5 was paid as interest.

CAN SOMEONE PLEASE HELP ME JIMIN WILL BLESS YOU IF YOU DO

Umnica [9.8K]

Answer:

see explanation

Step-by-step explanation:

Since XY bisects ∠ WXZ then ∠ WXY = ∠ YXZ , thus

7x - 7 = 5x + 3 ( subtract 5x from both sides )

2x - 7 = 3 ( add 7 to both sides )

2x = 10 ( divide both sides by 2 )

x = 5

(b)

∠ WXY = 7x - 7 = 7(5) - 7 = 35 - 7 = 28°

(c)

∠ YXZ = 5x + 3 = 5(5) + 3 = 25 + 3 = 28°

(d)

∠ WXZ = ∠ WXY + ∠ YXZ = 28° + 28° = 56°

X/2.7 + 3.6=4.8 solve for x

weqwewe [10]

Answer:

3.24

Step-by-step explanation:

1) minus the whole number, 3.6 from both sides:

x/2.7 +3.6 = 4.8 -----> x/2.7 = 1.2

2) multiply both sides by 2.7 to get the x value on its own:

x/2.7 = 1.2 -------> x = 3.24

3) finally x is on its own with a value on the other side... x = 3.24
