Answer:

1st Picture: d = -16

2nd Picture: g = -13.8

Step-by-step explanation:

1st Picture: Divide both sides by -11 to balance both sides and get the answer.

2nd Picture: Subtract 1.2 from both sides.

Answer:

Question 6:

We have -12.6 = g + 1.2, so we move the 1.2 to the left side to get -13.8 = g because when you move a number you are essentially minusing that number so 1.2 becomes -1.2 .

Question 7:

We have 176 = -11d so we divide by -11 to get -16 = d.

A sports equipment researcher investigated how different types of wood used to make baseball bats might affect batting. The researcher selected a sample of 80 batters from summer baseball leagues and randomly assigned the batters to one of two groups: the ash bat group or the maple bat group. The mean number of hits for each group was recorded at the end of the season, and the difference in the sample means was calculated. Which of the following is the appropriate inference procedure for analyzing the results of the investigation?
A. A one-sample t-interval for a population mean
B. A one-sample t-interval for a sample mean
C. A matched pairs t-interval for a mean difference
D. A two-sample t-interval for a difference between sample means
E. A two-sample t-interval for a difference between population means

Answers

Answer:

A two-sample t -interval for a difference between population means

Step-by-step explanation:

i just took the test

The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

Analysis the results of the investigation:

Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.

Therefore, The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

How do I solve this?

Answers

Answer:

Step-by-step explanation:

In order to find the answer. You first have to find the measure of the whole circle, which is 180.

Then you subtract 180-95 to find y.

180-95=85

So y=85

Then you subtract 180 from 80

180-80=100

So x=100

z=80

So the answer is D.

Answers

Answer:-5+x<-1

Step-by-step explanation:

Answer:

H. -5 + x < -1

Step-by-step explanation:

Okay so let's first look at our little graph thing. What is it saying? It's telling us that what ever x is, it is NOT 4 (because the circle is not filled in) and it is less than 4 (because it's all shaded in before 4). Now that we know this, lets look at our possible answers.

F. x - 3 < 7

Now, for all of these possible answers, we can solve them exactly like normal equations (like x - 3 = 7).

x - 3 < 7

[add 3 to both sides to leave the x by itself]

x < 10

Whoa, that's not right! We don't even have 10 on our graph, so F is out of the running.

G. x + 6 [tex]\leq[/tex] 10

Okay, let's work smarter, not harder here. So we can see that there is a greater than or equal to sign there. So even if we solve it and we get 4 as the answer, our graph doesn't include 4. So we can throw this answer out right away.

H. -5 + x < -1

Solve like a normal equation in the first one.

-5 + x < -1

[add 5 to both sides to leave the x by itself]

x < 4

Hey! We got something! So let's read this with words. So whatever x is, it does not include 4, and is less than 4. So now looking back on our first brainstorm of the graph, this is in line with what we want.

So this is the answer! Yay!

Just for fun let's look at the last possible answer.

I. x - 8 > -4

Again, solve like a normal equation.

x - 8 > -4

[add 8 to both sides to leave x by itself]

x > 4

Oh! Another 4! But this time the sign is different. Let's read it again with words. So whatever x is, it does not include 4 (ok, good), and is greater than 4 (oh, not good). Our graph showed us that x is less than 4. So this answer is not the answer.

So again, we keep H. as our correct answer.

An airline might first consider the average woman's hip breadth when designing seats. Why would the airline use women instead of men when determining the maximum width of an airline seat?

Answers

Answer:

Airlines would use women instead of men because women usually have wider hips compared to the average men. So if they give enough room for the average women, then there will be enough room for the average man.

somebody please answer only 11. and 13. ANSWER QUICKLY

Answers

11. y=x+4
13. y=1/4x +1

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept, value of y when x=0

11.

Since we are given the point (0,4) we already know that b=4

slope is m=(y2-y1)/(x2-x1), using our two points (0,4)(-1,3) we have

m=(3-4)/(-1-0)

m=-1/-1=1 so the line is

y=x+4

12.

Again they gave us point (0,1) so we know b=1, from points (0,1)(4,2) we find

m=(2-1)/(4-0)

m=1/4 so our line is

y=x/4+1 (or more neatly)

y=(x+4)/4

Find the exact angular velocity in radians per hour wind W= 4.1 rpm

Answers

Answer:

1545.66 rad/h

Step-by-step explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

[tex]4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h[/tex]

So, the required angular velocity is 1545.66 rad/h.

Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Which statement best describes the authors viewpoint in A Flag with 50 Stars?The author maintains that the 50-star flag is too complicated.The author is critical of the president's response.The author thinks simple accomplishments receive too much credit.The author believes people of all ages can accomplish great things.
