Jax has a weekly math test. His scores on the last 5 tests are 78,92,86,94,95. What score does he need to have an average of 90

lara [203]

Answer:

x = 95

Step-by-step explanation:

Given that,

Jax scores on the last 5 tests are 78,92,86,94,95.

We need to find the score he need to have an average of 90.

The formula for average of few number is given by :

Average = sum of observations/total no of observation

Let he score x in test 6. So,

$90=\dfrac{78+92+86+94+95+x}{6}\\\\90=\dfrac{445+x}{6}\\\\540=445+x\\\\x=95$

So, he must score 95 in the next test so that its average is 90.

What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?

Answer:

x in {-6, -2, 4}

Step-by-step explanation:

The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.

x +6 = 0 ⇒ x = -6

x -4 = 0 ⇒ x = 4

x +2 = 0 ⇒ x = -2

The zeros of the function are the x-values -6, -2, and 4.
