Answer:

pointed upward

Step-by-step explanation:

The coefficient of the quadratic term, a, determines how wide or narrow the graphs are, and whether the graph turns upward or downward. A positive quadratic coefficient causes the ends of the parabola to point upward.

Eight less than a number is the same as four the number increased by seven

bekas [8.4K]

Let's write that as an equation.

x-8=4x+7

So, you must solve for x by putting all of x on one side then solving for the value of one x.

x-8=4x+7
-8=3x+7
-15=3x
-5=x

Check your work.

(-5)-8=4(-5)+7
-13=-13

1. Many Alpine ski centers base their calculations of revenues and profits on the belief that the average skier ski’s four times

pshichka [43]

Answer:

We cannot infer at the 10% significance level that the assumption of ski centers is wrong

Step-by-step explanation:

The null hypothesis for this question can be stated as

Null hypothesis H0: =4

Alternate hypothesis Ha:

The test is two tailed

Standard Deviation –

= 2

z=(4.84-4)/(2/sqrt(63))

=3.33

Z(0.1/2)=1.645 is less than Z =3.334

Hence, we will reject H0

Hence, the average growth skier ski’s four times a year is not true

13. Translate the following verbal phrase

Artyom0805 [142]

a) algebraic expression

$\frac{3+x}{5}=10$

b) Solve and find value of x

x=47

Step-by-step explanation:

We need to translate the following verbal phrase into an algebraic equation

The quotient of three more than a number and five is ten

Let the number be x

three more than a number is written as: 3+x

Since quotient is 10 so,

The algebraic expression will be:

$\frac{3+x}{5}=10$

Now, <u>solving to find value of x</u>

$\frac{3+x}{5}=10$

Multiplying both sides by 5

$\frac{3+x}{5}*5=10*5\\3+x=50$

Now Subtract -3 from both sides

$3+x-3=50-3\\x=47$

So, value of x=47
