5+4=9 right but 9 divided by 2 is 4.5 you have to even out the numbers 1like 5+4=9 but 4.5 *4.5 also equals 9.

I hope this helped.

You would split an uneven number in half, by multiplying the uneven number by 5, and adding a decimal in between the numbers. (i.e. 9 x 5 = 45 = 4.5) Hope this helps:)

Cindy struck out 7, 14, 6, 4, 5, and 6 batters in softball games this season. In discussing her stats with a newspaper reporter,

Murljashka [212]

Answer:

The coach's statement is not misleading because her average strikeouts is 7.

Where as the coach also tells that it is 7.

Step-by-step explanation:

The average is taken out by adding the observations and dividing by the total number of observations.

X`= ∑x/n where n is the number of observations.

Average = 7 + 14 + 6 + 4 +5 +6 /6

Average = 42/6= 7

The coach's statement is not misleading because her average strikeouts is 7.

Where as the coach also tells that it is 7.

Steve wants to know what the average ACT scores of students graduated from his high school is. He randomly selected 25 students

beks73 [17]

Answer:

[a]. sample is 25 randomly selected students

also population is all students

[b]. (20.0, 23.0)

[c]. (8.8, 24.2)

Step-by-step explanation:

here is a step by step process to solving this, i hope you find this helpful.

1). The population is all students who graduated from his school while the

sample is 25 randomly selected students from the email list

2). given alpha = 1-0.86=0.14

critical z value(two tailed) for 86% confidence level is:

z=normsinv(0.07) or normsinv(0.93)=1.476

Margin of error=1.476*(4.6/SQRT(20))=1.5

86% confidence interval for population mean

=21.5+/-1.5

=(20.0, 23.0)

3). if population standard deviation is not known,we will use t distribution.

df=20-1=19

t*=tinv(0.05,19)=2.093

Margin of error=2.093*(5.7/sqrt(20))=2.7

95% confidence interval for population mean

=21.5+/-2.7

=(18.8, 24.2)

cheers i hope this helps!!!!

Answer:

100 beats per minute

Step-by-step explanation:

If it takes 28.8 secs for the piano to play 48 beats, then it would take 60 secs (1 minute) to play x number of beats.

To find the value of x, which is the number of beats the piano makes per minute, let's set the proportion as shown below:

28.8 secs = 48 beats

60 secs = x beats

Cross multiply

28.8*x = 60*48

28.8x = 2,880

Divide both sides by 28.8

x = 2,880/28.8

x = 100

✅Thus, if the Piano plays 48 beats in 28.8 secs, therefore, the tempo of the piano in beats per minute would be 100 BPM

Answer:

<u>Given</u>

Equation 5x - y = 12

and

Inequality 5x - y > 12

<em>See the graphs attached</em>

To draw the graphs follow the rules we described in the previous questions.

1. Identify x-intercept and y-intercept and connect them to have the line.
2. Shade the region above or below the line for the inequality.

We see the only difference the expressions have is the equation or inequality symbols.

Equation symbol means the graph of the equation is a line.
Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".

We can state that the inequality excludes the line and includes only the region above the same line.
