Answer:

{-1.75}

Step-by-step explanation:

The given equation is

x-2=5(x+1)

Let as assume f(x) be left hand side and g(x) be the right hand side.

f(x)=x-2

g(x)=5(x+1)

The solution set of given equation is the intersection point of f(x) and g(x).

Table of values are:

For f(x)                    For g(x)

x      f(x)                  x          g(x)

0      -2                   0           5

2       0                    -1          0

Plot these corresponding ordered pairs on a coordinate plan and connect them by straight lines

From the below graph it is clear that the intersection point of f(x) and g(x) is (-1.75,-3.75).

Therefore, the solution set of given equation is {-1.75}.

Answer:

Find the attached

Step-by-step explanation:

We have been given the following expression;

(x-2)=5(x+1)

We are required to determine the graph of the solution set. To do this we formulate the following set of equations;

y = x - 2

y = 5(x+1)

We then graph these two equations on the same cartesian plane. The solution will be the point where these two graphs intersect.

Find the attachment below;

A person has $10,100 to invest in two different stock. Stock ABC costs $32 per share and pays dividends of $1.20 per share. Stoc
marusya05 [52]

Answer:

$ 3199.0

Step-by-step explanation:

Let the number of shares of ABC = x

and XYZ = y

writing each as a linear equation

32 x + 23 y = 10100  equation 1

1.2 x + 1.4 y = 540

1.4 y = 540 - 1.2 x

y = (  540 - 1.2 x) / 1.4

substitute for y in equation 1

32 x + 23( 540 - 1.2 x) / 1.4 = 10100

32 x + 8871.43 - 19.71 x = 10100

collect the like terms

32 x -  19.71 x = 10100 - 8871.43

12.29 x = 1228.57

x = 1228.57 / 12.29 = 99.97

the amount of money to be invested in ABC shares = 99.97 × $ 32 = $ 3199.0

kow [346]

Answer:

The answer is - sample.

Step-by-step explanation:

Based on the set of 356 surveys that were completed and returned, the researcher finds that these students spend an average of 3.1 hours each day watching television.

For this study, the set of 356 students who returned the surveys is an example of a SAMPLE.

A sample is defined as a small part that shows what the whole population is like.

A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per
timofeeve [1]
3 lbs of Cashews, and 7 lbs of Peanuts

$4.00P + 6.50C = ($4.75/lbs)(10lbs)
$4.00(7) + $6.50(3) = $47.50
$28.00 + $19.50 = $47.50
$47.50 = $47.50

Therefore it's 3lbs of Cashews

The true average diameter of ball bearings of a certain type is supposed to be 0.05 in. A one-sample t-test will be carried out
satela [25.4K]

Answer:

a) H0: \mu \leq \mu_o

H1: \mu > \mu_o

n = 13 represent the sample size

t = 1.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 13-1=12

We can calculathe the p value with this formula:

p_v = P(t_{12} >1.6) = 0.068

Since p_v >\alpha we fail to reject the null hypothesis on this case at 5% of significance.

b) H0: \mu \geq \mu_o

H1: \mu < \mu_o

n = 13 represent the sample size

t = -1.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 13-1=12

We can calculathe the p value with this formula:

p_v = P(t_{12}

Since p_v >\alpha we fail to reject the null hypothesis on this case at 5% of significance.

c) H0: \mu \geq \mu_o

H1: \mu < \mu_o

n = 25 represent the sample size

t = -2.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 25-1=24

We can calculathe the p value with this formula:

p_v = P(t_{24}

Since p_v we can reject the null hypothesis on this case at 1% of significance.

Step-by-step explanation:

Part a

For this case we assume that we are testing the following system of hypothesis

H0: \mu \leq \mu_o

H1: \mu > \mu_o

n = 13 represent the sample size

t = 1.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 13-1=12

We can calculathe the p value with this formula:

p_v = P(t_{12} >1.6) = 0.068

Since p_v >\alpha we fail to reject the null hypothesis on this case at 5% of significance.

Part b

For this case we assume that we are testing the following system of hypothesis

H0: \mu \geq \mu_o

H1: \mu < \mu_o

n = 13 represent the sample size

t = -1.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 13-1=12

We can calculathe the p value with this formula:

p_v = P(t_{12}

Since p_v >\alpha we fail to reject the null hypothesis on this case at 5% of significance.

Part c

For this case we assume that we are testing the following system of hypothesis

H0: \mu \geq \mu_o

H1: \mu < \mu_o

n = 25 represent the sample size

t = -2.6 represent the calculated statistic

The degrees of freedom are given by:

df = n-1 = 25-1=24

We can calculathe the p value with this formula:

p_v = P(t_{24}

Since p_v we can reject the null hypothesis on this case at 1% of significance.
