Answer:

The is answer is 120sq. ft.

Step-by-step explanation:

To find the area mulitply 10 by 12 and you get 120.

Answer: 90

Step-by-step explanation:

450/5 or 450 divided by 5

you can work this out by figuring out 45/5 which is 9

so 450/5 equals 90

he should read 90 pages per day

Answer:

90

Step-by-step explanation:

Because if you divide the pages into the 5 day it would be 90

450 divide by 5 = 90

Answer:

16 times

Step-by-step explanation:

2 out of 5 is 40%

40 x 40% = 16

Answer:

Part A

The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend

The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend

Part B

P-value from;

Tables, 0.1 < P([tex]\chi^2[/tex] < 4.12) < 0.9

Chi-square calculator, P([tex]\chi^2[/tex] < 4.12) = 0.87

Step-by-step explanation:

The given data is presented as follows;

[tex]\begin{array}{ccc}Day&&Number\\Fri&&21\\Sat&&19\\Sun&&10\end{array}[/tex]

The significance level, α = 0.05

Part A

The hypothesis is to test that the given injuries and illnesses occur with equal frequency of the weekend

The null hypothesis H₀; The injuries and illnesses have no relationship in the weekend

The alternative hypothesis Hₐ; The injuries and illnesses occur with equal frequency on the weekend

Let the expected frequency, each day of the weekend = (21 + 19 + 10)/3 = 50/3 = 16.[tex]\overline 6[/tex]

We get;

[tex]\begin{array}{ccc}Day & Observed \ Number& Expected \ Number \\Fri&21& 16.\overline 6\\Sat&19&16.\overline 6\\Sun&10&16.\overline 6\end{array}[/tex]

The chi-square test statistics

[tex]\chi^2[/tex] = (21 - 50/3)²/(50/3) + (19 - 50/3)²/(50/3) + (10 - 50/3)²/(50/3) = 4.12

The [tex]\chi^2_u[/tex] with (3 - 1) = 2 degrees of freedom = 5.991

The decision rule, [tex]\chi^2[/tex] > 5.991, we reject the null hypothesis

Given that we have [tex]\chi^2[/tex] = 4.12 < 5.991, we fail to reject H₀, therefore, there is not enough statistical evidence to suggest that the meal plan are related at α = 0.05

Part B

From the chi-square table, we have the p-value at 2  degrees of freedom for the test statistic of 4.12 is between 0.9 and 0.1

Using the chi-square calculator, we have;

P([tex]\chi^2[/tex] < 4.12) = 0.87.

Answer:

For 6 days,  Samantha ran less than 56/8 mile

Step-by-step explanation:

The remaining part of the question is attached

Solution

Given

As we know

56/8 can be reduced to 5 3/4

Hence, if we see the plot we can determine that Samantha  ran 6 times less than  5 3/4 miles

For 6 days,  Samantha ran less than 56/8 mile

Answer:

650 cm²

Step-by-step explanation:

Use the formula 2(lw+wh+lh)

Plug in the stuff: 2(5*9+9*20+5*20)=2(45+180+100)=2(325)=650 cm²

And there you go!

Answer:

-42

Step-by-step explanation:

Following Order of Operations, we have to multiply before subtracting, so

[tex]2-2*22[/tex]

[tex]=2-44[/tex]

[tex]=-42[/tex]

Using order of operations, we get -42.

Answer:

470 [tex]cm^{3}[/tex]

5x5x10 = 250

720-420 = 470

Answer:

common form to write the equation of a circle in is the center-radius form. The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.

Answer:

x² + y² = 16

Step-by-step explanation:

We need to write the standard equation of circle with , centre (0,0) and radius 4 unit . The Standard equation of the circle ⭕ is ,

=> ( x - h)² + (y -k)² = r²

=> ( x -0)² + (y-0)² = 4²

=> x² + y² = 16 .

• Hence the equation of the circle is x² + y² = 16.
