Which statement about the solution of the inequality k<-3 1/4 is true?

Juliette [100K]

Answer: Last option

The number -8.4 is a solution to the inequality because -8.4 is located to the left of $-3\frac{1}{4}$ on the number line.

Step-by-step explanation:

Note that: $-3\frac{1}{4} =-3-\frac{1}{4} =-3.25$

The inequality is:

$k$

The inequality is:

This means that the inequality includes all values of the number line that are less than -3.25 or that are to the left of -3.25

__-8.4_________-3.25_-3____0___0.9____________7.1__

Note that the number -8.4 is less than -3.25, because it is to its left on the number line.

Then the correct statement is:

The number -8.4 is a solution to the inequality because -8.4 is located to the left of $-3\frac{1}{4}$ on the number line.

inysia [295]

Answer:

B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed.

Step-by-step explanation:

We make this conclusion based on these reasons:

We are told that the "null hypothesis was rejected" after the "manager feels that the pressure variability has changed., meaning the null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.
"changes in the manufacturing process" form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.

It is based on the above reasons that the null hypothesis was rejected.

During cooking, chicken loses 10% of its weight due to water loss. In order to obtain 1,170 grams of cooked chicken, how many gr

sweet-ann [11.9K]

Working backwards,

1,170×.10 =?
=117
So we know that 10% of 1,170 is 117. Now, add them together.
1,170+117=?
=1,287
Therefore, 1,287 grams of uncooked chicken must be used.

forsale [732]

Answer:

They must sell 106 more pizzas to earn $750.

Step-by-step explanation:

We are given that Mrs. Canale class is selling frozen pizzas to earn morning for a field trip. For every pizza sold, the class makes $5.35.

They have already earned $182.90, but they need $750. We have to find that how many more pizzas must they sell to be able to earn $750.

So, Firstly we will find that how much money did they have to earn more to be able to reach at $750.

Since, it is given that they have already earned $182.90.

So, Amount of more money they have to earn to reach at $750 = Final amount - Amount they already have

= $750 - $182.90 = $567.1

That means they have to earn $567.1 more to be able to reach at $750 mark.

Also, it is known that the price of every pizza sold = $5.35

So, Number of pizza that should be sold to earn an amount of $567.1 is given by;

Number of pizzas = $\frac{567.1}{5.35}$ = $\frac{5670}{535}$ = 106

Therefore, Mrs. Canale class must sell 106 more pizzas to be able to earn a total amount of $750.
