Which inequality represents the number line below?
x< 2
x > 2
x _< 2
x >_ 2

Answer:

[tex]t=480[/tex]

Step-by-step explanation:

Given

[tex]-100 = -\frac{t}{5} - 4[/tex]

Required

Solve for t

[tex]-100 = -\frac{t}{5} - 4[/tex]

Add 4 to both sides

[tex]4-100 = -\frac{t}{5} - 4+4[/tex]

[tex]4-100 = -\frac{t}{5}[/tex]

[tex]-96 = -\frac{t}{5}[/tex]

Multiply both sides by -5

[tex]-5*-96 = -\frac{t}{5} *-5[/tex]

[tex]-5*-96 = t[/tex]

[tex]480 = t[/tex]

[tex]t=480[/tex]

Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Testing A as the midpoint, we have:

[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]

[tex](5,2) = \frac{1}{2}(10,4)[/tex]

[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]

[tex](5,2) = (5,2)[/tex]

The above equation is true. Hence, A is the midpoint of B and C

Complete question is;

On a given day, the proportion of workers from Company B who purchase a coffee from the company cafeteria is 0.62 and the proportion of workers from Company C who purchase a coffee from the company cafeteria is 0.71. A random sample of 40 workers was selected from Company B and another random sample of 40 workers was selected from Company C. The proportion of workers from Company B who purchased coffee was p^_B = 0.70 and the proportion of workers from Company C who purchased coffee was p^_C = 0.75.

What is the correct unit of measurement for the mean of the sampling distribution p^_B - p^_C?

A) Days

B) Dollars

C) Companies

D) Workers

E) There are no units associated with the mean of the sampling distribution

Answer:

E) There are no units associated with the mean of the sampling distribution

Step-by-step explanation:

We are given;

Population proportion for workers from Company B who purchase a coffee from the company cafeteria as 0.62

Population proportion for workers from Company C who purchase a coffee from the company cafeteria as 0.71

Now, we were told that a random sample of 40 each were selected from both company B & C and the sample proportion were;

p^_B = 0.70 and p^_C = 0.75

Now, this proportions don't have any units as it is based on a ratio of the number of people that purchased coffee to the number of people surveyed.

Thus we can conclude that p^_B - p^_C will not have any units associated with it.

The possible outcomes of the difference in proportions of the two samples

based on on the individual proportions are not associated with a unit.

Reasons:

The given parameters are;

The proportion of workers of Company B who purchase coffee from the

Company B workers that purchase coffee from the cafeteria = 0.62

Company A workers that purchase coffee from the cafeteria = 0.71

Number of workers in the sample from Company B = 40

Number of workers in the sample from Company A = 40

Proportion of Company B workers who purchase coffee, [tex]\hat p_B[/tex] = 0.71

Proportion of Company C workers who purchase coffee, [tex]\hat p_C[/tex] = 0.75

Required:

The unit of the mean of the sampling distribution of [tex]\mathbf{\hat p_B - \hat p_C}[/tex]

Solution:

The proportion of the workers that purchase coffee is given by the ratio of the number of workers that purchase coffee to the number of workers in the sample.

Therefore;

[tex]\displaystyle \hat p = \mathbf{\frac{Coffee \ buying \ workers}{Total \ number \ of \ workers}}[/tex]

Given that the unit of the numerator and denominator are both workers,

that divide out, we have that the [tex]\mathbf{\hat p}[/tex], [tex]\mathbf{\hat p_B}[/tex], [tex]\mathbf{\hat p_C}[/tex] and therefore [tex]\hat p_B - \hat p_C[/tex] are not

associated with a unit.

Therefore;

The correct option is; E. There are no units associated with the mean of the sampling distribution.

Answer:

57 pisquets

Step-by-step explanation:

Ratio of pisquets:vreels = 10:7

Ratio on Frank's rew farm: x:40

since ratios are equivalent, you'd so the same on both sides. To get from 7 to 40 u multiply by a number, so to get from 10 to x u have to multiply by that same number. To find this number, divide 40 by 7: 40/7 = 5.7

Then, multiply this by 10: 5.7 x 10 = 57

there are roughly 57 pisquets on his farm.

Answer:

2700

Step-by-step explanation:

106%-> 2862

100%->2700

Answer:

in previous material it was shown that the digit sum of the product of two integers is equal to the digit sum of the product of the digit ... For instance, 66/8 = 8.25. ... For example, 35/7=5; the digit sum of the quotient is 5 and the digit sum of 35 is 8.

Missing: 59.4 ‎| Must include: 59.4

Answer:

7.2

Step-by-step explanation:

Change the divisor 8.25 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

5940 ÷ 825 = 7.200

and therefore:

59.4 ÷ 8.25 = 7.200

Both calculated to 3 decimal places.

Q11

Measure of angles for figure 1:

Measure of angles for figure 2:

The angle is formed by two rays at a common point of the two rays.

For given figure 1:

∠1+144=180 (Sum of angles on same side of transversal is 180°)

∠1=180-144

∠1=36

∠5+144=180(Sum of angles on a line is 180°)

∠5=180-144

∠5=36

Similarly, ∠3=180-56

∠3=124

∠4+36+56=180(Sum of all angles of a triangle is 180°)

∠4=180-36-56

∠4=88

∠2+36+88=180

∠2=56

Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.

For given, figure 2:

∠1=35(Alternate angle on same side of transversal are equal)

∠2=180-35

∠5=180-35-90(Sum of all angles of a triangle is 180°)

∠5=55

∠4+55=180(Sum of angles on a line is 180°)

∠4=180-55

∠4=125

Similarly, ∠2=180-35(Sum of angles on a line is 180°)

∠2=145

∠3=180-35-90(Sum of all angles of a triangle is 180°)

∠3=55

Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55
