Answer:

i think 150

Step-by-step explanation:

sorry if its wrong im just trying to help

Based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.

Given this information, the scatterplot below depicts the correlation between the number of baseballs used in 14 games and the number of pitches thrown in these games.

Making forecasts about the future is possible with a scatter plot. You can draw a line, referred to as a best-fit line, that is near the majority of the data points in order to aid in the forecasts. A line should be drawn with around half of the data points above and half below it.

Thus, based on the scatterplot, The best prediction of the number of baseballs that will be used if 275 pitches are thrown will be 150. Option A is correct.

(3√2y)2 = (2)2

18y = 4

Add 4 to both sides

18y = 4

Divide both sides by 18

A possible solution is :

y = (2/9)

Answer:

y=2/9

Answer:

x=8

Step-by-step explanation:

3x-4=2x+4

Subtract 2x from each side using the subtraction property of equality

We want to get all the x 's on one side

3x-2x-4=2x-2x+4

x-4 = 4

Add 4 to each side using the addition property of equality

We want all the constants on one side

x-4+4= 4+4

x= 8

Answer:

x=8

Step-by-step explanation:

3x-4=2x+4

Subtract 2x on both sides

Your equation will look like

x-4=4

Add the four on both sides

Since x equals one you don't divide x

your answer will be x=8

Answer:

r = -39

Step-by-step explanation:

So we are trying to solve the equation for r.

-6(2r + 8) = -10(r - 3)

Divide both sides by -2. (This will make distributing much easier.)

3(2r + 8) = 5(r - 3)

Distribute the 3 on the left side and the 5 on the right side,

6r + 24 = 5r - 15

Subtract 24 from both sides.

6r = 5r - 39

Subtract 5r from both sides.

r = -39

So now we have solve the equation.

Answer:

a

[tex]\% E = 0.9 \%[/tex]

b

[tex]\%E_1 = 10.1 \%[/tex]

Step-by-step explanation:

From the question we are told that

The probability that an employees suffered lost-time accidents last year is [tex]P(e) = 0.06[/tex]

The probability that an employees suffered lost-time accident during the current year is

[tex]P(c) = 0.05[/tex]

The probability that an employee will suffer lost time during the current year given that the employee suffered lost time last year is

[tex]P(c | e) = 0.15[/tex]

Generally the probability that an employee will experience lost time in both year is mathematically represented as

[tex]P(c \ n \ e) = P(e) * P(c \ |\ e)[/tex]

=> [tex]P(c \ n \ e) = 0.06* 0.15[/tex]

=> [tex]P(c \ n \ e) = 0.009[/tex]

Generally the percentage of employees that will experience lost time in both year is mathematically represented as

[tex]\% E = P(e \ n \ c ) * 100[/tex]

=> [tex]\% E = 0.009 * 100[/tex]

=> [tex]\% E = 0.9 \%[/tex]

Generally the probability that an employee will experience at least one lost time accident over the two-year period is mathematically represented as

[tex]P(e \ u \ c) = P(e) + P(c) - P(e \ n \ c)[/tex]

=> [tex]P(e \ u \ c) = 0.06 + 0.05 - 0.009[/tex]

=> [tex]P(e \ u \ c) = 0.101[/tex]

Generally the percentage of the employees who will suffer at least one lost-time accident over the two-year period is mathematically represented as

[tex]\%E_1 = P(e \ u \ c) * 100[/tex]

=> [tex]\%E_1 = 0.101* 100[/tex]

=> [tex]\%E_1 = 10.1 \%[/tex]

Answer:

1 - Paco

2 - Tim

3 - Jenny

4 - Maria

Step-by-step explanation:

Tim will not be in positions 1 or 4, as 1 and 4 represent the ends of the line.  Jenny cannot be in positions 1 or 4, as she is between two people.  Paco will not be in positions 2 or 4, as he is only in an odd numbered position. Maria will be in position 4, as none of the other three can be at position 4.  Paco will be in position 1, as Tim and Jenny cannot be at position 1.  The two positions left are 2 and 3. We'll assume that 1 represents the front of the line. Since Tim has to be in front of Jenny, he will take the position with the lower number, which is 2. This leaves Jenny with 3.

Step-by-step explanation:

Answer:

The probability of 213 or fewer cases of such cancer in a group of 479,908 people is 0.2776.

Step-by-step explanation:

We are given that assuming that cell phones have no​ effect, there is a 0.000462 probability of a person developing cancer of the brain or nervous system. We, therefore, expect about 222 cases of such cancer in a group of 479,908 people.

Let [tex]\hat p[/tex] = sample probability of a person developing cancer of the brain or nervous system.

The z-score probability distribution for the sample proportion is given by;

                            Z  =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, p = population probability of a person developing cancer of the brain or nervous system = 0.000462

            n = sample of cell phone​ users = 479,908

Now, the probability of 213 or fewer cases of such cancer in a group of 479,908 people is given by = P([tex]\hat p[/tex] [tex]\leq[/tex] [tex]\frac{213}{479,908}[/tex] )

     P([tex]\hat p[/tex] [tex]\leq[/tex] 0.000444) = P([tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] [tex]\leq[/tex] [tex]\frac{0.000444-0.000462}{\sqrt{\frac{0.000444(1-0.000444)}{479,908} } }[/tex] ) = P(Z [tex]\leq[/tex] -0.59)

                                 = 1 - P(Z < 0.59) = 1 - 0.7224 = 0.2776

The above probability is calculated by looking at the value of x = 0.59 in the z table which has an area of 0.7224.

These results suggest about media reports that cell phones cause cancer of the brain or nervous​ system that there is around 28% chance that 213 or fewer cases of such cancer in a group of 479,908 people can take place.

[tex]12.5[/tex] hours

The unitary method is a methodology for solving problems that involves first determining the value of a single unit and then multiplying that value by the required value.

Time taken by [tex]4[/tex] bunnies to eat crops [tex]=10[/tex] hours

Time taken by [tex]1[/tex] bunny to eat crops [tex]=\frac{10}{4}[/tex] hours

Time taken by [tex]5[/tex] bunnies to eat crops [tex]=\frac{10}{4}\times 5[/tex]

                                                              [tex]=12.5[/tex] hours

So, [tex]5[/tex] bunnies eat the same crops in [tex]\boldsymbol{12.5}[/tex] hours.

Answer:

16 times out of 64

Step-by-step explanation:

So, I could be wrong, but basically:

9, 10, and 11 are only 3 of the 12 possible outcomes that could happen.

3 out of 12 is 1/4.

What this means is that for every 4 times he spins the pointer, he can expect to get 9, 10, or 10 once.

Or 25% of the time

1/4 of 64 is 16.
