If there is 6 times as many blue cars as white cars, share it in the ratio 6:1.
6 + 1 = 7
35 ÷ 7 = 5
6 x 5 = 30
1 x 5 = 5
Answer: 30 blue cars and 5 white cars

Solve using the substitution method:<br><br>y = -2x - 7<br>y = 3x + 3​
levacccp [35]
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x

-5x-7= 3
+7. +7
-5x= 10

Divide -5 on both sides and you get x= -2

Then substitute -2 in the first equation

-2(-2)-7
4-7
Y= -3

Find the domain and range of the function represented by the graph. A Domain: {−2,−1,1,2} Range: {−2,1,2}{−2,1,2} B Domain: −2≤x
Brilliant_brown [7]

Answer:

B) Domain: -2≤x≤2   Range: -2≤x≤3

Step-by-step explanation:

The domain is the x-values, in this case all the numbers between -2 and 2.  The range is the y-values, which are the numbers between -2 and 3.  So the answer is

B) Domain: -2≤x≤2

Range: -2≤x≤3

Let x be a random variable representing the price of a Congo-imported black diamond. Let the higher price be p. Then,
P(x < p) = P(x < (p - mean)/sd) = P(x < (p - 60,430)/21,958.08) = P(z < 2)
Therefore,
(p - 60,430)/21,958.08 = 2
p - 60,430 = 2 x 21,958.08 = 43,916.16
p = 34,916.16 + 60,430 = 104.346.16

Therefore, The required price is $104,346.16
