Answer:

1/3

Step-by-step explanation:

due to her having triplits it will be a 1/3 chance that they will all be boys because you need to take in account the three children

Answer:

Step-by-step explanation:

There are 8 different ways that the order of the children is 1/8 for each one.

So for boy * boy * boy = 1/2 * 1/2 * 1/2 = 1/8

All of the other possibilities also produce 1/8 because each child has a possibility of 1/2 to be a boy or a girl.

The product of the two equation in which one has single power of variable and another one has the highest power of variable two, is -2a³+9a²+45a+6ab²+18b².

Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,

[tex]p=a\times b[/tex]

Here, (a, b) are the real numbers.

The binomial equation given in the problem is,

[tex]a+ 3[/tex]

The second equation given in the problem is,

[tex]-2a^2 +15a+ 6b^2[/tex]

The product of these two equations are,

[tex]p=(a+3)\times (-2a^2 +15a+ 6b^2)\\p=-2a^3+15a^2+6ab^2-6a^2+45a+18b^2\\p=-2a^3+9a^2+45a+6ab^2+18b^2[/tex]

Thus, the product of the two equation in which one has single power of variable and another one has the highest power of variable two, is -2a³+9a²+45a+6ab²+18b².

Answer:5,200ft and 145in is less than a mile and 40in

Step-by-step explanation: I got this answer by first figuring out how many feet are in 145in so i did 145 divided by 12 which gave me 12.083... so I added just 12 to 5,200 which gives 5,212

Then I know that there are 5,280ft in 1 mile which is already bigger than 5,212 then I still add 40 divided by 12 which equals 3.3... to the total which gives me 5,283ft which is more than 5,212

x-intercept : (-1.2,0) 

y-intercept : (0,-0.7)

Step-by-step explanation:

Hello!

An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.

Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.

A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.

Answer:

5.5 hours

Step-by-step explanation:

1. Understand

A person can travel at the speed of 40 miles per hour (mph). If the speed is increased by 50%, how long will it take to cover 330 miles?

a. What is asked?  How long will it take to cover 330 miles travelling at a speed 50% greater than 40 mph

b. What are the given facts?

Current Speed = 40 mph

New Speed = 40 mph + 50% of 40 mph

Distance = 330 miles

2. Plan

Calculate the new speed and then use the two speeds to calculate time based on Distance = Speed x Time

What is the formula to solve the problem?

Distance = Speed x Time

3. Solve

Show your solution.

Original Speed = 40 mph

New Speed = 40 + (0.5)*(40):  New = 60 mph

Time at New Speed is:

Distance = Speed x Time

330 miles = (60 mph)*(Time)

Time = (330 miles)/(60 miles/hour)

Time = 5.5 hours

4. Check

Distance = Speed x Time

How far does a person travel going 60 miles/hour for 5.5 hours?  Is it 330 miles?

Distance = (60 mph)*(5.5 hours)

Distance = 330 miles

YES

Answer:

C

Step-by-step explanation:

the 50 miles don't really matter in this situation. 180$ per hour will be 180h (as we don't know the number of hours used) and the 50$ gas fee, which is what C is representing.

Answer:

C:  C = 180h + 50

Step-by-step explanation:

180 per hour, with h representing how many hours, and then  you need a $50 gas fee. So, the answer would be C = 180h + 50

Step-by-step explanation:

a) x + 4 = 12

=> x + 4 - 4 = 12 - 4

=> x = 8

d) - 14 = 2x

=> -14/2 = 2x/2

=> -7 = x

x = -7

b) x + 5,1 = x + x

1 = x + x

1 = 2x

1/2 = 2x/2

x = 1/2 or 0.5

e) 5 = 4x

=> 5/4 = 4x/4

=> x = 5/4 or 0.8

c) 6x = x - 15

=> x - 15 = 6x

=> -15 = 6x - x

=> -15 = 5x

=> -15/5 = 5x/5

=> x = -3

f) x + 8 = 2x + 3

x+8=2x+3

x+8−2x=2x+3−2x

−x+8=3

−x+8−8=3−8

−x=−5

−x/−1 = −5/−1

Answer:

250

Step-by-step explanation:

1. Find the total amount of people interviewed

You asked 15 students over 4 periods of lunch. That means you have to multiply:

15 x 4 = 60. You asked 60 people total.

2. Solve

You know that 25 people chose pizza out of the 60 people that you interviewed. That would make a fraction: 25/60

Now, there are 600 people, and the question is asking you how many people will get pizza based on the ratio of 25/60

So, in this case, 25/60 = x/600

You have to multiply 60 by 10 to get 600 as your denominator.

So, similarly, you have to multiply 25 by 10 to keep the same ratio.  

25 x 10 = 250

Hence, 250/600 people will buy pizza.

Based on the data given on the amounts Chris and Sam are paid, we can infer that Chris earns $0.75 more per hour than Sam.

Chris earns $8.25 an hour according to the equation that shows how he is paid of y = 8.25x.

The amount earned by Sam can be found as:

= Any value of y / Corresponding value of x

= 30 / 4

= $7.50 per hour.

The difference between their pay is:

= 8.25 - 7.50

= $0.75

In conclusion, Chris earns $0.75 more.
