if the product (2x + 3)(x + k) is 2x^2 + 13x + 15, what is the value of k?
Answers
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

Coach Gannon Bought 8 Bags Of Sunflower Seeds For The Baseball Game. Each Bag Has 2 1/4 Cups Of Seeds. If Coach Gannon Has 12 Baseplayers On The Team, How Many Cups Of Seeds Can Each Player Have?
Answers
First, let’s multiply 8 and 2 1/4 together. You would get 18.
Next, you would divide that by 12. You would get 1.5 cups.
Last, you turn that into fraction form, if you need to. You would get 1 1/2 cups.
The answer is 1.5 or 1 1/2. Please mark Brainliest if this helped you. :))

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?
Answers
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

(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.
Answers
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

what is the formula of mean ???? pls explain
Answers
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]

Answers
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.
