F(0) = 1 must be true
<span>If x=1,
f(1)=(1-1)*g(1)=0*g(1)=0
So, you get that f(1)=0 is true.
</span>hope this helps

Answer:

$f(1)=0$

Step-by-step explanation:

we know that

If $(x-1)$ is a factor of the polynomial f(x)

then

For $x=1$

the polynomial must be equal to zero

$f(1)=0$

The distances male long jumpers for State College jump are approximately normal with a mean of 263 inches and a standard deviati

Effectus [21]

Answer:

His jump was of 272.45 inches

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 263, \sigma = 14$

75th percentile

X when Z has a pvalue of 0.75. So X when Z = 0.675

$Z = \frac{X - \mu}{\sigma}$

$0.675 = \frac{X - 263}{14}$

$X - 263 = 14*0.675$

$X = 272.45$

His jump was of 272.45 inches
