Answer:

the answer is c

Step-by-step explanation:

Given:

Combine weight of two cats, Zeus and Athena = 13 pounds

Zeus weighs 5 pounds less than Athena.

To find:

The weight of Athena.

Solution:

Let x pounds be the weight of Athena.

Zeus weighs 5 pounds less than Athena.

Weight of Zeus = x - 5 pounds

Combine weight of two cats, Zeus and Athena = 13 pounds

[tex]x+(x-5)=13[/tex]

[tex]2x-5=13[/tex]

Add 5 on both sides.

[tex]2x=13+5[/tex]

[tex]2x=18[/tex]

Divide both sides by 2.

[tex]x=\dfrac{18}{2}[/tex]

[tex]x=9[/tex]

Therefore, the weight of Athena is 9 pounds.

Answer:

Step-by-step explanation:

Given the functions:

f (x) = x^2

g(x) = 3x + 1

h(x) = 2x

We are to look for  f + (goh)

First we need to get the composite function goh

goh = g(h(x))

g(h(x)) = g(2x)

To get g(2x) we will substitute x in g(x) as 2x as shown below:

Given g(x) = 3x+1

g(2x) = 3(2x)+1

g(2x) = 6x+1

f + goh = x² + (6x +1)

f + goh = x² + 6x +1

Jim wrote goh as 2(3x+1) instead of 3(2x) + 1. The composite function that Jim looked for was hog not goh.

The correct solution is f + goh = x² + 6x +1

Answer:

A) Fraction = 3/5, Percentage = 60%

B) Fraction = 1/15 , Decimal = 0.083333 ≈ 0.08

C) Ratio = 1:9, Fraction = 1/9

Step-by-step explanation:

A) The total amount of money Jack received = $75

Jack's spent on shoes = $45

The proportion he spent on shoes

= $45/$75

= 3/5

Converting this fraction to percentage

= 3/5 × 100% = 60%

B.What proportion of his birthday money went toward music?

The total amount of money Jack received = $75

Jack's spent on music = $5

The proportion he spent on music

= $5/$75

= 1/15

Converting this fraction to decimal

= 1/15 = 0.0833333333

It is a repeating decimal.

Approximately to the nearest hundredth = 0.08

C. Write the ratio of money Jack spent on music to money Jack spent on shoes.

The ratio of money spent on music to the ratio of my money spent on shoes

Music : Shoes

$5 : $45

1:9

The fraction that js equivalent to the ratio is 1/9

Answer:

[tex]F = 45.4[/tex]

[tex]S = 12.68[/tex]

Step-by-step explanation:

Given

Represent the sons age with S and the father's age with F

[tex]S * F = 576[/tex]

[tex]F = 5S - 18[/tex]

Required

Determine F and S

Substitute 5S - 18 for F in the first equation

[tex]S * (5S - 18) = 576[/tex]

Open Bracket

[tex]5S\² - 18S = 576[/tex]

Equate to 0

[tex]5S\² - 18S - 576 = 0[/tex]

Solve using quadratic formula:

[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a = 5[/tex]

[tex]b = -18[/tex]

[tex]c = -576[/tex]

[tex]S = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]S = \frac{-(-18)\±\sqrt{(-18)^2 - 4*5*-576}}{2 * 5}[/tex]

[tex]S = \frac{18\±\sqrt{324 + 11520}}{10}[/tex]

[tex]S = \frac{18\±\sqrt{11844}}{10}[/tex]

[tex]S = \frac{18\±\108.8}{10}[/tex]

[tex]S = \frac{18+108.8}{10}[/tex] or [tex]S = \frac{18-108.8}{10}[/tex]

[tex]S = \frac{126.8}{10}[/tex]  or [tex]S = \frac{-90.8}{10}[/tex]

[tex]S = 12.68[/tex] or [tex]S = -9.08[/tex]

Since, age can't be negative.

We have that:

[tex]S = 12.68[/tex]

Recall that:

[tex]F = 5S - 18[/tex]

[tex]F = 5 * 12.68 - 18[/tex]

[tex]F = 45.4[/tex]

Hence:

The father is 45 years old and the son is 13 years old (Approximated)

Answer:

a)0.764

b)0.116

c)Expected value =1.75

Variance=1.1375

Step-by-step explanation:

Total Number of employees = 20

Number of promotions awarded = 7

Probability of success p =[tex]\frac{7}{20}[/tex]

Probability of failure q = [tex]1-\frac{7}{20}=\frac{13}{20}[/tex]

We randomly select 5 applications

a) What is the probability that at most 2 employees were promoted?

We will use binomial

[tex]P(X=x)=^nC_r p^r q ^{n-r}\\P(X\leq 2)=P(X=0)+P(X=1)+P(X=2)\\P(X\leq 2)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+^{5}C_1 (\frac{7}{20})^1 (\frac{13}{20})^{5-1}+^{5}C_2 (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+\frac{5!}{1!(5-1)!}(\frac{7}{20})^1 (\frac{13}{20})^{5-1}+\frac{5!}{2!(5-2)!} (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=0.764[/tex]

b)What is the probability that no employees were promoted?

[tex]P(X=0)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=0.116[/tex]

c)

[tex]E(X)=np=5 \times (\frac{7}{20})=1.75\\Var(X)=npq=5 \times (\frac{7}{20}) \times \frac{13}{20}=1.1375[/tex]

Answer:

It is D.

Step-by-step explanation:

proof I just took it

Answer:

Yes, she is. The exact product of 602 and 341 is 205,282.

Step-by-step explanation:

To determine the exact product of 602 and 341, both numbers must be multiplied, obtaining the result. To do this, said number can be decomposed, to facilitate the operation and to be able to corroborate the accuracy of the result.

So, we can multiply 602 by 300, plus 602 by 40 and 602 by 1, and add the results.

Therefore, since 602 times 300 is equal to 180,600 (602 x 300 = 180,600); that 602 times 40 is equal to 24,080 (602 x 40 = 24,080); and since 602 times 1 is equal to 602, all those values must be added.

So 180,600 plus 24,080 equals 204,680. And in turn, 204,680 plus 602 equals 205,282. Therefore, the proposed result is correct.

Answer:

$524.30

535*.02(20%)

10.7

535-10.7=

524.3

Answer:

$107

Step-by-step explanation:

First you have to add up the costs and you get a total of $535

Then you need to make 535 equivalent to 100 then divide by 20 to get 107

Answer:

5 5/6

Step-by-step explanation:

Change the mixed numbers to improper fractions, and you get -9/2 + 31/3, which adds up to 35/6, then divide 35 by 6, which changes it back to a mixed number, 5 5/6.

Also, is the X a multiplier?

Answer:

0.001035

Step-by-step explanation:

Mean (m) = 152.09 mm

Standard deviation (σ) = 19.62 mm

Sample size (n) = 25

Length being 140mm or shorter (x) : x ≤ 140

Using the Zscore relation :

Zscore = (x - m) / (σ/√n)

Zscore = (140 - 152.09) / (19.62/√25)

Zscore = (140 - 152.09) / (19.62/5)

Zscore = −3.081039

P(Z ≤ −3.08) = 0.001035

Answer:

13w-6x

Step-by-step explanation:

Answer:

Step-by-step explanation:

3.65 ⋅ 10 = 36.5

3.65 ⋅ 100 = 365

3.65 ⋅ 1000 = 3,650

3.65 ⋅ 10000 = 36,500

3.65 ⋅ 100000 = 365,000

There are 5 zeroes on the last one.

This means that 100,000 is 10 to the power of 5.

I think but your question makes no sense

Answer: Y= 3/2x + 3

Step-by-step explanation:

Using the Y =mx+b formula, you count how many units it is going up and that is the numerator. Then you count how many units it's going to the right, and that's the denominator. Then the starting point is (0, 3) so now you plug those in and b is the starting point and the fraction is mx so you are left with the answer y= 3/2x+3

Answer:

6, 7,  and 14 feet.

Step-by-step explanation:

x+2x+x-1=27

4x-1=27

4x=27+1

4x=28

x=7

2x=14

x-1=6

So the three sides, in order, are 6, 7,  and 14 feet.
