Does anybody know this?

Answer:

(A) When the sample size increases, both α and β may decrease.

Step-by-step explanation:

Which of the following is correct?

(A) This option is right.

When a sample's size increases, the values for alpha and beta may decrease; if and only if sample size is the denominator in the slope equation (in each case) and the numerator stays the same (that is, ceteris paribus; all other things being equal). The larger the denominator, the smaller the slope value for alpha and beta.

(B) This option is wrong

Type 2 error can only occur when you fail to reject a true H0

(C) This option is wrong

Type 1 error can only occur if or when you don't reject a false H0

(D) This option is wrong

The level of significance is the probability of a Type 1 error, not the probability of a Type 2 error.

Step-by-step explanation:

The range of the relation of centimeters as a function of inches y ≥0.

A function's range includes all conceivable values for y. Y = f(x) is the formula to determine a function's range. It is only a function in a relation if each x value has exactly one y value.

Given:

Column 1          Column 2

       2                       5.08

       4                       10.16

       7                       17.78

       10                      25.4

       13                      33.02

As, we know the range is the output values.

So, range is {5.08, 10.16, 17.78, 25.4, 33.02}

Thus, the range is ≥ 0.

Hence, the range of the y ≥0.

Answer:

75%

Step-by-step explanation:

Look at it this way since there is 8 what u could do is 1/4 so 2 of them are 25% 4 of them are 50% 6 of them are 75% and all 8 are 100%

Answer:

75%

Step-by-step explanation:

The circle is divided into 8 parts and 6 of those are shaded.

so as a fraction it would be 6/8

simplified it would be 3/4

percent is out of 100 so you have to make the denominator as 100

25 x 4 (the denominator of 3/4) is 100

25 x 3 ( the numerator of 3/4) is 75 you have to multiply both the numerator and denominator by the same number.

now you have 75/100

which is 75 percent

Answer:

a. 0.1971

Step-by-step explanation:

Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:

[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]

Given that:

μ = 1050 kWh, σ = 218 kWh

For x = 1100 kWh

[tex]z=\frac{x-\mu}{\sigma}=\frac{1100-1050}{218} =0.23[/tex]

For x = 1225 kWh

[tex]z=\frac{x-\mu}{\sigma}=\frac{1225-1050}{218} =0.80[/tex]

From the normal distribution table, P(1100 < x < 1225) = P(0.23 < z < 0.8) = P(z < 0.8) - P(z < 0.23) = 0.7881 - 0.5910 = 0.1971

Mass of Mars , [tex]M=6.42\times 10^{23}\ kg[/tex].

Radius of Mars ,

[tex]R=3397\ km\\\\R = 3.397\times 10^6\ m[/tex]

To Find :

The acceleration of gravity on the surface of Mars.

Solution :

Acceleration due to gravity is given by :

[tex]g_m = \dfrac{GM_m}{R_m^2}\\\\g_m =\dfrac{(6.67\times 10 ^{-11}\ m^3\ kg^{-1}\ s^{-2})(6.42\times 10^{23}\ kg) }{(3.397\times 10^6\ m)^2}\\\\g_m = 3.71\ m/s^2[/tex]

Therefore, the acceleration of gravity on the surface of Mars is 3.71 m/s².

Hence, this is the required solution.

Answer:

70 section of Finite math and 80 section of Applied calculus

Step-by-step explanation:

As in each section, finite math has 80 student and applied calculus has 70 students

80x + 70Y = 11,200................(i)

There are 150 sections in a semester

x + y = 150..................................(ii)

Multiply equation (ii) by -70

-70x - 70y = 10,500

Add equation (i) and equation (iii)

80x + 70Y = 11,200

-70x - 70y = 10,500

10x            = 700

x = 700/100

x= 70

Substitute x in equation (ii)

x + y = 150

70 + y = 150

y = 150 - 70

y = 80

Hence, 70 section of finite math and 80 section of applied calculus should the department offer in order to fill all sections and accommodate all of the students.

[tex]3\ point\ word = 5[/tex]

[tex]2\ point\ word = 15[/tex]

[tex]1\ point\ word = 10[/tex]

Step-by-step explanation:

Given

Represent

3-point word with T;

2-point with U and

1-point with V

[tex]U = 5 + V[/tex] --- (1)

If total questions is 30, then

[tex]T + U + V = 30[/tex] --- (2)

If total points is 55, then

[tex]3T + 2U + V = 55[/tex] --- (3)

Substitute 5 + V for U in (2) and (3)

[tex]T + U + V = 30[/tex] --- (2)

[tex]T + 5 + V + V = 30[/tex]

[tex]T + 5 + 2V = 30[/tex]

[tex]T + 2V = 25[/tex] ---- (4)

[tex]3T + 2U + V = 55[/tex] --- (3)

[tex]3T + 2(5 + V) + V = 55[/tex]

[tex]3T + 10 + 2V + V = 55[/tex]

[tex]3T + 10 + 3V = 55[/tex]

[tex]3T + 3V = 55 - 10[/tex]

[tex]3T + 3V = 45[/tex]

Divide through by 3

[tex]T + V = 15[/tex] ---- (5)

Subtract (5) from (4)

[tex](T + 2V = 25 )- (T + V = 15)[/tex]

[tex]T - T + 2V - V = 25 - 15[/tex]

[tex]V = 10[/tex]

Recall that:

[tex]U = 5 + V[/tex]

[tex]U = 5 + 10[/tex]

[tex]U = 15[/tex]

Substitute 10 for V in (5)

[tex]T + V = 15[/tex]

[tex]T + 10 = 15[/tex]

[tex]T = 5[/tex]

Answer:

X=18

Step-by-step explanation:

3x+4/2 = 29

Multiply both sides by 2 :

2(3x+4)/2 = 29*2

Simplify :

3x+4= 58

Subtract 4 from both sides :

3x + 4 - 4 = 58 - 4

Simplify  :

3x = 54

Divide both sides by 3:

3x / 3 = 54 /3

Simplify  :

X = 18
