Answer:

The probability of Alex and Jane getting picked is 0.0112 or 1.12

Step-by-step explanation:

Ok, so the probability that Alex is picked is 0.08, then in order for jane to be picked it is another 0.14.

That means that we must figure out what 14% of 0.08 is 0.0112

0.0112 = 1.12%

good luck mate!

Answer:

Question 3: There are 12 boys in the class.

Question 4: 120 cookies were not oatmeal raisin.

Question 5: Target offers the best deal.

Step-by-step explanation:

If the ratio of girls to boys is 3:2, and there are 18 girls, that means there will be [tex]\frac{18}{3}[/tex] * 2 = 6 * 2 = 12 boys.

Because there are 200 cookies total, and [tex]\frac{2}{5}[/tex] of them are oatmeal raisin, that means that [tex]\frac{3}{5}[/tex] of the cookies aren't oatmeal raisin. 200 * [tex]\frac{3}{5}[/tex] = 40 * 3 = 120 cookies that aren't oatmeal raisin.

The cookies at Kroger have a unit rate of $0.45 per cookie, the cookies at Meijer have a unit rate of $0.50 per cookie, the cookies at Walmart have a unit rate of $0.38 per cookie, and the cookies at Target have a unit rate of $0.20 per cookie. So Target has the better buy.

Answer:

2x

Step-by-step explanation:

Given the expression  10x^3 + 16x^2 - 18x, we are to find the GCF

First find the factors

10x^3 = 2 * 5 * x * x^2

16x^2 = 2 * 8 * x * x

18x = 2 * 9 * x

From the factors shown, you will see that 2 and x are the common factors. Hence the GCF of the expression is 2x

Answer:

Terminal point: (√3/2, 1/2); tan θ = √3/3

Step-by-step explanation:

The terminal point is (√3/2, 1/2) and the value of tanθ is √3/3 option (A) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

θ = π/6

Taking tan on both sides:

tanθ = tanπ/6 = 1/√3 = √3/3

Terminal points:

= (cosπ/6, sinπ/6)

= (√3/2, 1/2)

Thus, the terminal point is (√3/2, 1/2) and the value of tanθ is √3/3 option (A) is correct.

Given :

Two numbers 25 and 17.

How much larger is the sum of the numbers 25 and 17 compared to their difference? (Two small brackets will be used.)

To Find :

How much larger is the sum of the given numbers as compared to their difference.

Solution :

Sum of given numbers, S = 25 + 17 = 42 .

Difference of given numbers, D = 25 - 17 = 8 .

The difference between S and D is, S - D = 42 - 8 = 34 .

Therefore, sum of the numbers is larger by 34 than in difference.

Answer:

5.08 years

Step-by-step explanation:

We are to solve for time using compound interest formulas

For Hailey

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 3/8% = 2.375.

Time = ?

Hence,

First, convert R as a percent to r as a decimal

r = R/100

r = 2.375/100

r = 0.02375 per year,

Then, solve the equation for t

t = ln(A/P) / r

t = ln(4,000.00/2,000.00) / 0.02375

t = 29.185 years

≈ 29.19 years

For Sophie

Principal = $200

Amount = Double of Principal = $4000

Rate = 2 7/8% = 2.875

Time = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 2.875/100

r = 0.02875 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 0.02875/365)] )

t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 7.8767E-5)] )

t = 24.11 years

How much longer would it take for Hailey's money to double than for Sophie's money to double?

For Hailey it takes 29.19 years

For Sophie it takes 24.11 years

We find the difference

= 29.19 - 24.11

= 5.08 years

Therefore, it would take 5.08 years for Hailey's money to double than Sophie

Answer: 65.22%

Step-by-step explanation: 15 is more than half of 23 which means it can’t be the other options because the others aren’t more than half.

65.22 % of teachers ordered the salad bar

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

According to the question

A school cafeteria offers three lunch options on Mondays:

Spaghetti, sub sandwiches, or salad bar.

Percentage of teachers ordered the salad bar

Total number of teachers = 23

Total number of teachers ordered the salad bar = 15

= [tex]\frac{15}{23}[/tex]

= 0.6522

= 65.22%

Thus, 65.22 % of teachers ordered the salad bar

Answer:

Q = (9, 4 )

Step-by-step explanation:

Use the midpoint formula and equate to the coordinates of the midpoint.

M = ([tex]\frac{x_{1}+x_{2} }{2}[/tex] ) , ([tex]\frac{y_{1}+y_{2} }{2}[/tex] )

let the coordinates of Q = (x, y ) , R = (- 7, 0 ) , then

[tex]\frac{x-7}{2}[/tex] = 1 ( multiply both sides by 2 )

x - 7 = 2 ( add 7 to both sides )

x = 9

and

[tex]\frac{y+0}{2}[/tex] = 2 ( multiply both sides by 2 )

y = 4

Thus Q = (9, 4 )
