Answer:

x = 3 and x = 4

Step-by-step explanation:

3x - 4 + 4x - 8 = x^2

7x -12 = x^2

x^2 - 7x + 12 = 0

(-4)*(-3) = 12 and (-4)+(-3) = -7

(x-3)(x-4) = 0

x - 3 = 0. x = 3

x - 4 = 0. x = 4

A purchaser of electric relays buys from two suppliers, A and B. Supplier A supplies two of every three relays used by the compa

Reptile [31]

Answer: Our required probability is 0.3162.

Step-by-step explanation:

Since we have given that

n = 60

Probability of success = $\dfrac{2}{3}$

Probability that at most 39 of these relays come from supplier A would be

$P(X\leq 39)=binomcdf(60,\dfrac{2}{3},39)=0.3162$

Hence, our required probability is 0.3162.

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To covert Celsius temperature to

Solnce55 [7]

Answer:

see below

Step-by-step explanation:

The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.

So inequality which models this situation will be -40°C < T < 125°C

Now we have to show this inequality in Fahrenheit temperature with the help of $C=\frac{5}{9} (F-32)$

So the compound inequality in Fahrenheit temperature will be

$-40 < \frac{5}{9} (F-32) < 125$
