Answer:
A) The height of the water increases 2 inches per minute.
Step-by-step explanation:
Slope is the rate of change of height
m = (16 - 12)/(4 - 2) = 4/2 = 2
2 inch per min
Positive slope implies increase

State the conclusion based on the results of the test. The standard deviationstandard deviation inin the pressure required to open a certain valve is known to be sigma equals 1.3 psi.σ=1.3 psi. Due to changes in the manufacturing process, the quality-control manager feels that the pressurepressure variabilityvariability has changedchanged. The null hypothesis was rejected.Choose the correct answer below. A. There is not sufficient evidence that the mean of the pressure required to open a certain valve has not changed. B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. C. The mean of the pressure has not changed. D. The mean of the pressure has changed. E. There is sufficient evidence that the mean of the pressure required to open a certain valve has not changed. F. There is not sufficient evidence that the mean of the pressure required to open a certain valve has changed.
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.

if the product (2x + 3)(x + k) is 2x^2 + 13x + 15, what is the value of k?
Answer: k = 5
(2x + 3)(x + k)
= 2x.x +2x.k + 3x + 3k
= 2x² + x(2k + 3) + 3k
because (2x + 3)(x + k) is 2x^2 + 13x + 15
=> 3k = 15
2k + 3 = 10
=> k = 5

8 – 3(4x - 1) >= -49
Answer:
x≤61/12
Step-by-step explanation:
distribute the -3
8-12x+3≥-49
add like terms
12-12x≥-49
subtract 12 from both sides
-12x≥-61
divide by -12, when you divide by a neg the lessthan/greaterthan sign flips
x≤61/12

Yesterday you wanted to make an enormous batch of rolls, so you
borrowed some special yeast from your aunt's top-secret bread
research facility. Once you mixed the yeast, flour, and water, the
dough began to double in volume every minute! After 13 minutes, at
exactly 5:53, your bowl was hali full. At what time will your bowl be
full of dough?
Answer:
6:06
Step-by-step explanation:
After 13 minutes, at exactly 5:53, your bowl was half full. At what time will your bowl be full of dough?
We have;
1/2 full = 13 minutes
1 (full of dough) = x minutes
1/2x = 13 × 1
x = 13 ÷ 1/2
x = 13 × 2
x = 26 minutes
Hence the bowl would be full of dough after 26 minutes.
26 minutes - 13 minutes
= 13 minutes
This means dough increased in size
= After 13 minutes again.
The time at which your bowl be
full of dough is calculated as:
The initial time is was 1/2 full + 13 minutes
5:53 + 13 minutes
=5:66 minutes
= 6 hours 6 minutes = 6:06
The bowl would be full of dough at 6:06
what is the formula of mean ???? pls explain
Answer:
Mean is fairly simple. You add up all the numbers, then divide it by how many numbers you have.
Step-by-step explanation:
Take for example, you have 1, 2, 3, 4, 5
Add all those numbers up.
1+2+3+4+5
You get 15.
To get the mean, you simply divide 15 by 5.
Why?
Because there are 5 numbers present.
In simple words,
[tex]mean \: = \: \frac{sum \: of \: the \: observations}{no. \: of \: observations} [/tex]
I think of a number, square it, then subtract the original number. The result is 30. What could the number be

Answer:
I believe it is the first option but I'M NOT SURE.
Step-by-step explanation:
The reason I believe this is because distance can't be measured as a negative so it wouldn't be able to be represented as -5 but when calculating air pressure it can.
Some of Amber's daily activities are listed here. Use these descriptions to select the word or symbol that correctly completes each sentence. • Amber spends 3/16 of each day doing homework. • Amber spends 0.25 of each day at school. • Amber spends 1/3 of each day sleeping. (A) 3/16 of a day 0.25 of a day (B) 0.25 of a day 1/3 of a day (C) Amber spends time doing homework than she does at school. (D) Amber spends time sleeping than she does at school.
Answer: (D) Amber spends time sleeping than she does at school.
Step-by-step explanation:
Given that :
• Amber spends 3/16 of each day doing homework.
• Amber spends 0.25 of each day at school.
• Amber spends 1/3 of each day sleeping.
Hence,
Amber spends 0.1875 of a day doing homework, which is (0.1875 * 24) = 4.5 hours
0.25 of each day at school ; (0.25 * 24) = 6 hours
1/3 of each day sleeping ; (1/3 * 24) = 8 hours
Time spent sleeping = 8 hours
Time spent in school = 6 hours
