An auto maker estimates that the mean gas mileage of its sports utility vehicle is at least 20 miles per gallon. A random sample
Nady [450]

Answer:

Yes, we reject the auto maker's claim.

Step-by-step explanation:

H0 : μ ≥ 20

H1 : μ < 20

Sample mean, xbar = 18 ;

Sample size, n = 36

Standard deviation, s = 5

At α = 0.01

The test statistic :

(xbar - μ) ÷ s /sqrt(n)

(18 - 20) ÷ 5/sqrt(36)

-2 /0.8333333

= - 2.4

Pvalue from test statistic : Pvalue = 0.00819

Pvalue < α

0.00819 < 0.01

Hence, we reject the Null

Use the key features of the polynomial f(x) = −4x4 + 4x3 + 9x2 − 12x + 10 to describe its end behavior.
Aleks04 [339]

Answer:

The end behavior of a polynomial is determined by its grade, if it's an odd polynomial or an even polynomial. Also, another important characterstic is the leading coeffcient, because if it's positive, then the function will open to positive territory, this apply the most to even polynomials.

The given expression is

f(x)=-4x^{4} +4x^{3}+9x^{2}  -12x+10

As you can notice, the polynomial function has a grade of 4, that means it's an even function, with negative leading coefficient.

Therefore, the given function open towards negative side, that means it's end behavior is downside.

The image attached shows the graph of the function, there you can observe the end behavior we determined.

klio [65]

Answer:

The answer is 350 grams of sugar

Step-by-step explanation:

You use a ratio

\frac{6}{10} = \frac{210}{?}

Compare the numerators. Since  

6 ⋅ 35 =210  ,  multiply the denominator  10  by  35  to get  350
