Answer 1

Answer:

y = (-9/8)x + 7

Step-by-step explanation:

the line equation for slope intercert form looks like this

y = mx + b

m is the slope

b is the y intercept

The line intercepts the y at b= 7 (as noted in point (0, 7)

To find slope, use the 2 points given and the slope formula

m = (y2 - y1) / (x2-x1)

point (x1, y1) is  (0, 7) and

point (x2, y2) is (8, -2)

plug in the correct spots for m = (y2 - y1) / (x2-x1)

m = (-2 - 7) / (8 - 0) = -9 / 8

substitute y = mx +b = (-9/8)x + 7

I hope this helps :-)

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.

Step-by-step explanation:

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

The distance from Houston to
Galveston is about 50 miles. If there are
1.6 kilometers in a mile, what is the
distance from Houston to Galveston in
kilometers?

Answers

Answer:

distance from Houston to Galveston in  kilometers will be: 80km

Step-by-step explanation:

Given

The distance from Houston to  Galveston is about 50 miles.

i.e.

Kilometers in 1 Mile = 1.6 km

As the distance from Houston to  Galveston is about 50 miles, so

The distance from Houston to Galveston in  kilometers will be:

50(1.6) = 80   ∵ Kilometers in 1 Mile = 1.6 km

Therefore,

The distance from Houston to Galveston in  kilometers will be: 80km

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.

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

The mean undergraduate cost for tuition, room, board and fees for four-year colleges in the United States was found to be $26,489, with a standard deviation of $3204. If 36 of the four-year colleges are randomly sampled, find the probability that the mean cost for the sample schools is:

Answers

Answer:

0.1787

Step-by-step explanation:

It is given that the mean cost of undergraduate program for a four year institutions for tuition, rooms fees and board was =$26,489

And the minimum  standard deviation is given as σ = $ 3204

So, the mean normal deviation is , μ = 26,489

and the standard deviation is, σ = 3204

Thus, the probability of the mean cost for sample schools is 0.1787
