Select all the equations where z=5 is a solution.

Answer:

You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.

The probability of selecting a red marble the first time is 1313.

(This is because 4 out of 12 marbles are red and412412 reduces to 1313.

The probability of selecting a red marble the second time is 1313.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds = (13)2(13)2

=19=19.

So the probability of getting two reds is 1919.

Answer:

F

Step-by-step explanation:

To figure out if a set of angles are in a triangle, make sure they add up to 180

F) 58,70,62                 58 + 70 + 62 = 190      This option is incorrect

G) 41,68,71                   41 + 68 + 71 = 180       This option is correct

H) 68,60,52                68 + 60 + 52 = 180    This option is correct

J) 73,42,65                  73 + 42 + 65 =  180     This option is correct

Since option F did not equal 180, F is the answer.

Answer:

1. 37.5 metres.

2. 33.33 metres (May be wrong due to the answer but I used the correct solution to find the answer)

3. Refer to explanation.

Step-by-step explanation:

1. Find out how much Logan and Mila both swam.

1/3 of an hour =

60 minutes ÷ 3 = 20 minutes

Logan swam 750 metres for 20 minutes.

Mila swam 2/3 of Logan's distance.

Find out how much is 1/3 of Logan's distance in 1/4 of an hour.

3/3 = 750

1/3 = 750 ÷ 3 = 250

2/3 = 250 x 2 = 500

1/4 of an hour =

60 minutes ÷ 4 = 15 minutes

Mila swam 500 metres in 15 minutes.

To find out Logan's average swimming speed, here's the formula:

Total distance/total elapsed time

So it is 750/20 which is 37.5 metres.

2. Use the same formula I mentioned above in question 1 for average swimming speed, so it is...

500/15 = 33.33 metres

3. Other ways to compare Mila's and Logan's swimming speed is to find out the difference of the distance of how long they swam.

Use Mila's average swimming speed and find out how much metres she would swim if she swam for 20 minutes.

33.33 metres x 20 minutes = 666.6 metres

Answer:

The 2nd option:

1.339×10⁶

Step-by-step explanation:

To find the combined capacity, add the two values together so:

(8.12×10⁵ ) + ( 5.27 × 10⁵ )

It will be simpler to add if you change it out of its

standard form

812000+527000

= 1339000

Now you can write in back in standard form, which will be

1.339×10⁶

Answer:

18 children

Step-by-step explanation:

The computation of the more children went to scotland is as follows:

Given that

There is 200 children

out of which 18% went to wales i.e. = 200 × 18% = 36

And, 27% went to scotland i.e. = 200 × 27% = 54

So, the more children went to scotland is

= 54 - 36

= 18 children

27.5 /100 are running for a cause

Step-by-step explanation:

We know that 220/800 are running for a cause

Divide the top and bottom by 8 to get the fraction out of 100

220 /8 =27.5

800/8 = 100

27.5 /100 are running for a cause

Answer:

135

Step-by-step explanation:

Step-by-step explanation:

We know that the formula for slope is y=mx+b, with m equaling the slope itself and b equaling the y-intercept. Since the slope is -4, we can safely say that the equation starts off as y=-4x.

The y-intercept is (0,2). This means that the x-coordinate is 0 and the y-coordinate is 2, so the y-intercept is 2. Since 2 is being added, the equation is y=-4x+2

Answer:

y=-4x+2

Answer:

44

Step-by-step explanation:

1) we know that opposite sides of a parallelogram are congruent so

4x+28=10x+4

2) subtract 4 on both sides

4x+24=10x

3)subtract 4x on both sides

24=6x

4)divide by 6 on both sides

4=x

5)substitute for x

length of RS =10(4)+4

length of RD=44

The length of the side RS of the parallelogram PQRS is 44.

Given,

As we know in a parallelogram, the opposite sides are parallel and equal. So, in this case, side PQ is equal to side RS.

Computation:

[tex]\begin{aligned}\text{Side RS}&=\text{Side PQ}\\10\text{X}+4&=4\text{X}+28\\10\text{X}-4\text{X}&=28-4\\6\text{X}&=24\\\text{X}&=4\end{aligned}[/tex]

When the value of X is determined to be 4.

By using the substitution method the value of X will be used in the side RS to determine the length of RS.

[tex]\begin{aligned}\text{RS}&=10\text{X}+4\\&=(10\times4)+4\\&=40+4\\&=44\end{aligned}[/tex]

Therefore, the length of RS is 44.
