2x + 50 = 112

2x = 112 -50

2x = 62

x = 62:2

x= 31

If f(x)=-2x+3, g(x)=5x^2+4x-5, and h(x)=7x^2-8, find h(4)

iVinArrow [24]

Asked to find h(4). Hence, we don not need f(x) and g(x).

Substitute x=4 in h(x).

so, h(4) = 7*(4)^2 - 8 => 112 - 8 => 104

hope it helps.

One day, Karen bought 22 random cans of soup from a grocery store. Suppose that 5% of cans sold at that particular grocery store

zimovet [89]

Answer:

0.6765 = 67.65%

Step-by-step explanation:

This situation can be treated as a binomial model with probability of success (dented can) of p = 0.05.

In 22 random trials, the probability of at least one success is determined by:

$P(X>1) = 1-P(X=0)\\P(X>1) = 1 - (1-p)^{22}\\P(X>1) = 1 - (1-0.05)^{22}\\P(X>1) =0.6765$

The probability that Karen has bought at least one dented can is 0.6765 or 67.65%.
