Answer:

b) $120 , $ 80

Step-by-step explanation:

Ratio = 3 :2

Total = 3 + 2 = 5

3/5 of 200 = [tex]\frac{3}{5}*200[/tex]

                  = 3 * 40

                  = $ 120

2/5 of 200 = [tex]\frac{2}{5}*200[/tex]

                 = 2 * 40

                  = $ 80

Given parameters:

Area of the rectangle  = [tex]1\frac{2}{3}[/tex]ft²

Width of the rectangle  = [tex]\frac{5}{6}[/tex]ft

Unknown:

Length of the rectangle  = ?

Solution:

The area of a rectangle is given as:

 Area of rectangle  = length x breadth

 Now insert the parameters and solve for length

     [tex]\frac{5}{3}[/tex]   = L x  [tex]\frac{5}{6}[/tex]

        L  =   [tex]\frac{5}{3}[/tex]  x [tex]\frac{6}{5}[/tex]   = 2ft

Answer:

$16

Step-by-step explanation:

A sales person makes 8% on everything she sells

She sold $200 worth of merchandise

The amount of money that will be made can be calculated as follows

= 8/100 × 200

= 0.08 × 200

= $16

Hence the sales person will make $16

Answer: 19/25.

Step-by-step explanation:

Given data:

Large marbles = 14

Small marbles = 11.

8 large marbles = green.

5 of small marbles = white.

Solution:

If 8 of large marbles are green, therefore the remaining 6 are white.

Likewise for the small marbles the remaining 6 are green marbles.

Total number of marbles = 14 + 11

= 25.

P(small or green) = P(small) + P (green) – P (Both)

= 11/25 + 14/25 – 6/11

= 19/25

Answer:

Answer is 0.7536

Step-by-step explanation:

Large Marbles = 14   Small Marbles = 11

Green LM = 8            Green SM = 6

White LM = 6             White SM = 5

QUESTION:

If a marble is randomly selected from the box, what is the probability that it is small or it is green?

Note the use of "or" and not "and".

SOLUTION:

In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!

The formula for this probability is hence

P(A or B) = P(A) + P(B) - P(A and B)

Let A = The event that the selected marble is small

     B = The event that the selected marble is green

Total number of marbles = 14 + 11 = 25

P(A or B) = 11/25  +  (8+6)/25  -  [P(A) × P(B)]

P(A or B) = 11/25  +  14/25  -  [11/25 × 14/25]

               = 0.44  +  0.56  -  0.2464   =  1 - 0.2464  = 0.7536

Answer:

20.3π cm

Step-by-step explanation:

Area of a circle = 324 square cm

    πr² = 324

   [tex]\frac{22}{7}*r^{2}= 324\\\\ r^{2} = \frac{324*7}{22}\\\\ r^{2}= 103.09\\\\ r =\sqrt{103.09}\\\\[/tex]

  r = 10.15 cm

Circumference = 2πr

                         = 2 *  π * 10.15

                         = 20.3π cm

equation is 9+(4x) = 7

x = -0.5

Step-by-step explanation:

+ 9 to (4x) equals 7

9 + 4x = 7

4x = -2

x = -0.5

to prove:

9+(-0.5*4) = 7

9 + -2 = 7

Answer:

X=3/5

Step-by-step explanation:

Let number=X

Solution

2x+4=26/5

Cross multiply then we get

10x+20=26

10x=26-20

10x=6

X=6/10

X=3/5

So the no is 3/5

Answer:

A multiple is the result of multiplying a number by an integer. The least common multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers. To find the least common multiple you need to be able to identify the factors of the numbers you are working with.

Step-by-step explanation:

Answer:

The rocket ship will travel 2.1 × 10y miles.

Step-by-step explanation:

This question is incomplete, the complete question is;

A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.

The researcher chooses a random sample of 100 pregnant women who are over 40. Using the mean birth weight of the 100 babies in the sample, the researcher calculates the 95% confidence interval for μ.

With 95% confidence, the researcher estimates the mean birth weight of all babies born to women who are over the age of 40 to be between 2935 and 3135 grams.

The researcher wants to maintain the 95% level of confidence but report a confidence interval with a smaller margin of error. What should she do

a) Redo the study and choose a different sample of size 100

b) Redo the study, but this time with a sample size 64

c) Redo the study, but this time with a sample 225

Answer:

Option C) is the correct answer.

C) Redo the study, but this time with a sample 225

Step-by-step explanation:

Given that;

A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.

n = 100

95% confidence interval is given ( 2935, 3135)

But the researcher wants to maintain the 95% level of confidence as well as smaller margin of error.

Therefore we have to reduce the margin of Error

and we know that if the sample size increases, the margin of Error decreases i.e it becomes smaller.

so the best option for the researcher is to redo the study with a larger sample size so the margin of Error becomes smaller.

Option C) is the correct answer.

c) Redo the study, but this time with a sample 225

Answer:

b=120

Step-by-step explanation:

Using proportions, it is found that the final price of the new computer monitor is given by:

b. 120

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

It is regularly priced at $200 but it is now on sale for 25% off, hence 75% of $200 is paid, so:

P1 = 0.75 x 200 = 150.

You can also use your 20% off coupon, hence the final price is of 80% of $150, then:

FP = 0.8 x 150 = $120.

Which means that option B is correct.
