so you can not make the number smaller or reduce the fraction

ex.u can not simplify 11 over 12 because 11 is a prime number

Suppose that IQ scores in one region are normally distributed with a standard deviation of . Suppose also that exactly of the in

olga55 [171]

Answer: Hello your question is poorly written attached below is the complete question

answer : 101.8

Step-by-step explanation:

Given data :

Standard deviation ( б ) = 14

55% have IQ scores > 100

45% have IQ scores < 100

<u>Determine the mean IQ score for the region</u>

P ( X > x ) =

P ( Z ≥ ( 100 - μ ) / 14 ) = 0.55 also

P ( Z ≤ ( 100 - μ ) / 14 ) = 0.45

<em>using standard normal calculator </em>

100 - μ / 14 = Z₀.₄₅ = - 0.126

<em>resolving the relation above</em>

100 - μ / 14 = - 0.126

μ = 100 - 14 ( -0.126 )

= 101.764 ≈ 101.8

If C(x) = 4x^2 - 3, find the following<br> (a) C(0)<br> (b) C (-1)<br> (c) C (-2)<br> (d) C (-3/2)

NeTakaya

Step-by-step explanation:

$C(x)=4x^2-3\\\\C(0),\ C(-1),\ C(-2),\ C\left(-\dfrac{3}{2}\right)\\\\\text{Substitute each value}\ \left\{0, -1, -2, -\frac{3}{2}\right\}\ \text{instead}\ C(x):\\\\C(0)=4(0^2)-3=4(0)-3=0-3=-3\\\\C(-1)=4(-1)^2-3=4(1)-3=4-3=1\\\\C(-2)=4(-2)^2-3=4(4)-3=16-3=13\\\\C\left(-\dfrac{3}{2}\right)=4\left(-\dfrac{3}{2}\right)^2-3=4\left(\dfrac{9}{4}\right)-3=9-3=6$

Angelica had 8 more pairs of shoes than her mom. Together they have 30 pairs of shoes. How many pair of shoes does each one have

MAVERICK [17]

Answer:

The answer to your question is Angelica 19, her mom = 11

Step-by-step explanation:

Data

Angelica has 8 more than her mother

total number of shoes = 30 pairs

The Number of pairs Angelica has = a = ?

The Number of pairs her mother has = m = ?

Process

1.- Write two equation that help to solve this problem

a = m + 8 Equation l

a + m = 30 Equation ll

2.- Solve the system of equations by substitution

Substitute equation l in equation ll

(m + 8) + m = 30

-Solve for m

m + 8 + m = 30

2m = 30 - 8

2m = 22

m = 22/2

m = 11

3.- Find a

a = 11 + 8

a = 19

4.- Conclusion

Angelica has 19 pairs of shoes and her mom has 11
