Answer:

Sum of money = $600

Step-by-step explanation:

X = sum of money

Simple interest means that its the same percentage of interest for a given number of years.

The interest per annum is 5% for 3 years, so 5% x 3 = 15%

15% = 0.15 (as a decimal)

Now, we can put this into an equation:

0.15x = 90

x = 90 / 0.15

x = 600.

sum of money invested = $600

Answer:

[tex]\mu = x - z(\sigma)[/tex]

[tex]\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15[/tex]

Therefore, the mean monthly payment is $1137.15.

Step-by-step explanation:

What is Normal Distribution?

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.  

We are asked to find the mean monthly social security (OASDI) payment.

Mean monthly payment = μ = ?

We are given that the standard deviation is $116

One-fourth of payments are above $1214.87

One-fourth means 25%

[tex]P(X > x )= P(Z > z ) = 0.25\\\\P(X < x )= P(Z < z) = 1 - 0.25\\\\P(X < x )= P(Z < z) = 0.75\\\\[/tex]

From the z-table, the z-score corresponding to 0.75 is found to be 0.67

[tex]z = 0.67[/tex]

The mean is found by

[tex]x = \mu + z(\sigma)[/tex]

[tex]\mu = x - z(\sigma)[/tex]

Where

x = $1214.87

z = 0.67

σ = $116

[tex]\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15[/tex]

Therefore, the mean monthly payment is $1137.15.

Answer: 3. 0.287

Step-by-step explanation:

Let p be the true proportion of BB fans who favor that song.

As per given, Sample size for survey of Beach Boys fans = 394

Number of Beach Boys fans said that California girls was their fav song = 113

Then, the sample proportion of BB fans who favor that song: [tex]\hat{p}=\dfrac{113}{394}[/tex]

[tex]=0.286802030457\approx0.287[/tex]

Since sample proportion is the best estimate for the true proportion.

Hence, a point estimate for the true proportion of BB fans who favor that song is 0.287.

So, the correct option is 3. 0.287 .

Answer:

A. (1, -2)

Step-by-step explanation:

We can substitute the variables of x and y into the inequality of [tex]y < -|x|[/tex].

Let's start with A, -2 being y and 1 being x.

[tex]-2 < - |1|[/tex]

The absolute value of 1 is 1, and negating that gets us -1.

[tex]-2 < -1[/tex]

Indeed, -2 is less than -1! So A is a solution to the inequality.

Let's test the rest of them, just in case.

For B:

[tex]-1 < -|1|[/tex]

Absolute value of 1 is 1, negating it is -1.

[tex]-1<-1[/tex]

-1 is EQUAL to -1, not less than it, so is not a solution to the inequality.

Let's try C.

[tex]0 < -|1|[/tex]

Absolute value of 1 is 1, negating it is -1.

[tex]0 < -1[/tex]

0 is GREATER than -1, so that is not a solution to the inequality.

Answer:

-1.96

Step-by-step explanation:

Significance level or alpha level is the probability of rejecting the null hypothesis when null hypothesis is true. It is considered as a probability of making a wrong decision. It is a statistical test which determines probability of type I error. If the obtained probability is equal of less than critical probability value then reject the null hypothesis. In this question the sample of 500 defective tablets is under test. 20 tablets found to be defective so the null hypothesis is accepted as less than 6% of tablets are defective.

Step-by-step explanation:

In the two triangles ΔWVZ and ΔYXZ,

If the sides WV and XY are parallel and the segments WY and VX are the transverse.

∠X ≅ ∠V [Alternate angles]

∠W ≅ ∠Y [Alternate angles]

Therefore, ΔWVZ ~ ΔYXZ [By AA postulate of the similarity]

Option (2) will be the answer.

Answer:

t=1.283 seconds and

0.779 seconds

Step by step Explanation:

Given: h=18 ft

The given equation is h=2+33t-16t²

Then if we substitute the value of given h, h=18 ft into the given equation we have,

18=2+33t-16t²

Then if we re- arrange we have

16t²−33t+16=0

We can see that the above quadratic equation is in standard form, with a=16, b=33 and c=16 then we can use quadratic formula in solving it which is

t= −(−33±√[(−33) ²−4×16×16)]/(2×16)

= [33±√[1089−1024]/(32)

= [33±√[65]/(32)

=1.283 or 0.779 seconds

the two real roots , of the quadratic are:

1.283 and

0.779 seconds

t= 1.283 or 0.779 seconds

Hence, the ball is at 18 feet with height 0.779seconds after it has been thrown up and,

and is at 21 feet with height 1.283 seconds after after thrown down

Answer:

[tex] x+y = 125[/tex]   (1)

[tex] 5x+8y = 775[/tex]   (2)

We can solve for y from equation (1) and we got:

[tex] y = 125-x[/tex]   (3)

And replacing (3) into (2) we got:

[tex] 5x +8(125-x) = 775[/tex]

And solving for x we got:

[tex] 1000-3x = 775[/tex]

[tex] 3x= 225[/tex]

[tex] x=75 [/tex]

And solving for y from (3) we got:

[tex] x= 125-75 =50[/tex]

And the solution would be x = 50 and y =75

Step-by-step explanation:

For this problem we have the following system of equations:

[tex] x+y = 125[/tex]   (1)

[tex] 5x+8y = 775[/tex]   (2)

We can solve for y from equation (1) and we got:

[tex] y = 125-x[/tex]   (3)

And replacing (3) into (2) we got:

[tex] 5x +8(125-x) = 775[/tex]

And solving for x we got:

[tex] 1000-3x = 775[/tex]

[tex] 3x= 225[/tex]

[tex] x=75 [/tex]

And solving for y from (3) we got:

[tex] x= 125-75 =50[/tex]

And the solution would be x = 50 and y =75

[tex]1)\quad f(x)=\bigg\{\begin{array}{ll}12x&0\leq x <9\\18x-48&9\leq x \leq 24\end{array}[/tex]

2) D: x = [0, 24]

3) R: y = [0, 384]

4) see graph

Step-by-step explanation:

Eric's regular wage is $12 per hour for all hours less than 9 hours.

The minimum number of hours Eric can work each day is 0.

f(x) = 12x    for   0 ≤ x < 9

Eric's overtime wage is $18 per hour for 9 hours and greater.

The maximum number of hours Eric can work each day is 24 (because there are only 24 hours in a day).

f(x) = 18(x - 8) + 12(8)

    = 18x - 144 + 96

    = 18x - 48           for 9 ≤ x ≤ 24

The daily wage where x represents the number of hours worked can be displayed in function format as follows:

[tex]f(x)=\bigg\{\begin{array}{ll}12x&0\leq x <9\\18x-48&9\leq x \leq 24\end{array}[/tex]

2) Domain represents the x-values (number of hours Eric can work).

The minimum hours he can work in one day is 0 and the maximum he can work in one day is 24.

D:  0 ≤ x ≤ 24        →        D: x = [0, 24]

3) Range represents the y-values (wage Eric will earn).

Eric's wage depends on the number of hours he works. Use the Domain (given above) to find the wage.

The minimum hours he can work in one day is 0.

f(x) = 12x

f(0) = 12(0)

     =  0

The maximum hours he can work in one day is 24 (although unlikely, it is theoretically possible).

f(x) = 18x - 48

f(24) = 18(24) - 48

       = 432 - 48

       = 384

D:  0 ≤ y ≤ 384        →        D: x = [0, 384]

4) see graph.

Notice that there is an open dot at x = 9 for f(x) = 12x

and a closed dot at x = 9 for f(x) = 18x - 48

Answer:

There are 455 different  handfuls of 12 jellybeans possible

Step-by-step explanation:

From the given information;

we are told that there exist 50 kinds of jellybean for each of these colors (red, orange, green, yellow)

Also the jellybeans of each color are identical.  

i.e Let say y represent the color of the jellybean.

Then y₁ = y₂ = y₃ = y₄ corresponds to each of these colors (red, orange, green, yellow)

The objective is to determine how many different handfuls of 12 jellybeans are possible?

So;

y₁ + y₂ + y₃ + y₄ = 12

Therefore; the number of different  handfuls of 12 jellybean possible can be computed by using the formula:

[tex]C(r+k-1,r) = \dfrac{(r+k-1)!}{r! (k-1)!}[/tex]

where;

r =12 jellybeans

k = 4  types of colors

[tex]C(12+4-1,4) = \dfrac{(12+4-1)!}{12! (4-1)!}[/tex]

[tex]C(15,4) = \dfrac{15!}{12! (3)!}[/tex]

[tex]C(15,4) = \dfrac{15\times 14 \times 13 \times 12!}{12! (3)!}[/tex]

[tex]C(15,4) = \dfrac{15\times 14 \times 13 }{3!}[/tex]

[tex]C(15,4) = \dfrac{15\times 14 \times 13 }{3 \times 2 \times 1}[/tex]

[tex]C(15,4) =5\times 7 \times 13[/tex]

[tex]C(15,4) =455[/tex]

There are 455 different  handfuls of 12 jellybeans possible  

There are [tex]455[/tex] different handfuls of [tex]12[/tex] jellybeans that are possible.

Probability is termed as the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen. The probability formula is determined as the possibility of an event to happen is equal to the ratio of the number of outcomes and the total number of outcomes.

Given information are:

There are exist of [tex]50[/tex] kinds of jellybean of different colors i.e. red, orange, green, yellow.

The jellybeans of each color are identical.

i.e Let say [tex]y[/tex] represent the color of the jellybean.

Then [tex]y_1=y_2=y_3=y_4[/tex] corresponds to each of these colors (red, orange, green, yellow)

So,

[tex]y_1+y_2+y_3+y_4=12[/tex]

Therefore, the number of different handfuls of [tex]12[/tex] jellybean possible can be computed by using the formula:

[tex]C\left ( r+k-1,r \right )=\frac{\left (r+k-1 \right )!}{r!\left ( k-1 \right )!}[/tex]

where,

[tex]r=12[/tex] jellybeans

[tex]k=4[/tex] types of colors

[tex]C\left ( 12+4-1,4 \right )=\frac{\left (12+4-1 \right )!}{12!\left ( 4-1 \right )!} \\ C(15,4)=\frac{15!}{12!(3)!} \\ C\left ( 15,4 \right )=\frac{15\times 14\times 13\times 12!}{12!(3!)} \\ C(15,4)=\frac{15\times 14\times 13}{3!} \\ C(15,4)=\frac{15\times 14\times 13}{3\times2\times1} \\ C(15,4)=5\times7\times13 \\ C(15,4)=455[/tex]

So, the possibility are [tex]455[/tex] different handfuls of [tex]12[/tex] jellybeans.

cos(2*62.5136°)=-0.5740

Answer:

The Central Limit Theorem says that if the sample size is more than 30, the data follows a normal sampling distribution. Since the sample size is 180, and that is more than 30, a Normal sampling distribution can be used.

Since a normal sampling distribution can be used, we should FAIL TO REJECT the null hypothesis because p = 0.20, which is more than the significance level of α = 0.08. There is NOT sufficient evidence to suggest that the alternative hypothesis is true.

Answer:

The total profit when 240 members are enrolled is:

3,587,212.8 cents

Step-by-step explanation:

First of all, the total profit function is gotten by integrating the marginal profit function.

Integrate thus:

Total Profit = P(x) = [-0.0008x^4 ÷ 4] + [0.35x^3 ÷ 3] + [45.5x^2 ÷ 2]

P(x) = 0.0002x^4 + 0.1167x^3 + 22.75x^2

Next, substitute 240 for x, in the total profit function.

P(x) = 0.0002[240]^4 + 0.1167[240]^3 + 22.75[240]^2

P(x) = 663552 + 1613260.8 + 1310400

P(x) = 3,587,212.8 cents
