What is a correct name for the angle shown?
Masteriza [31]

Answer:

the answer is option B. angle S.

when naming an angle we place the vertex of the angle in the middle. here the angle is RST. But that option is unavailable. very often when there are no other angles interfering with the parent angle, we represent it using one letter that is the mid letter, the vertex. here in this case it is S.

A consumer group claims that the average annual consumption of high fructose corn syrup by a person in the U.S. is 48.8 pounds.
LenaWriter [7]

Answer:

6.7159

Step-by-step explanation:

\mu=48.8\\n=35\\\bar{x}=53.8\\\sigma=4.4\\\alpha=1\%=0.01

Null and alternative hypothesis :

H_0:\mu=48.8\\H_a:\mu>48.8

Test statistic,

t=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}

\Rightarrow t=\frac{53.8-48.8}{\frac{4.4}{\sqrt{35}}}

\Rightarrow t=\frac{5\times 5.91}{4.4}

\Rightarrow t=6.715

Test statistic t=6.715

P-value =P(t>6.715)

P- value =0.0001  by the p- table

Significance level 0.01

         p-value

  We reject H_0
