Write the faction ration for each of the following.
If m

Answer:

a =55

b =16

c = 25

d = 9

Step-by-step explanation:

of means multiply  is means equals

20% of a is 11

.20 a = 11

Divide by .20

a = 11/.20

a=55

75% of b is 12

.75 b =12

Divide by .75

b = 12/.75

b = 16

80% of c  is 20

.80 c =20

Divide by .80

c = 20/.80

c =25

200% of d is 18

2.00 d = 18

Divide by 2.0

d = 18/2

d =9

Answer:

10,404/334,084

Step-by-step explanation:

Given the polynomial

289r^2 - 102r + c

We are to find the value of c that will make it a perfect square

Divide through by 289

289r²/289 - 102r/289 + c/289

Half of the coefficient of r is 1/2(102/289)

Half of the coefficient of r = 102/578

Square the result

r² = (102/578)²

r² = 10,404/334,084

Hence the required constant is 10,404/334,084

Answer:

  $2,210.16

Step-by-step explanation:

The applicable formula for the account balance is ...

  A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. Here, we have P=2000, r=0.02, n=12, t=5. The balance is ...

  A = $2000(1 +0.02/12)^(12·5) = $2210.16

Answer:

<ADB = 75 degrees

Step-by-step explanation:

We know, a straight line has an angle of 180 degrees.

A = (180-143) = 37 degrees.

A + C = (37 + 38) = 75 degrees.

The angles of a triangle will always add up to 180 degrees.

<ADC = (180-75) = 105 degrees.

So,

<ADB = (180-105) = 75 degrees.

Hope, this will help. Please mark me brainliest.

Step-by-step explanation:

Supplies = 2 model cost

               = 2*64 = 128

Total cost = model + supplies

                 = 64 + 128

                  =192

Answer:

  B.  66 m

Step-by-step explanation:

Map and ground distances are proportional:

  ground/map = ground/(12 cm) = (11 m)/(2 cm)

  ground = (12 cm)(11 m/(2 cm)) = 66 m

The distance from A to B is 66 m.

A = 94.985 ft²

Answer:

[tex]x = 70^o[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To solve for x, we make use of:

[tex]x + 50^o + 60^o = 180^o[/tex] --- angles in a triangle

[tex]x + 110^o = 180^o[/tex]

Collect like terms

[tex]x = 180^o-110^o[/tex]

[tex]x = 70^o[/tex]

Answer:

We are 95% confident that the proportion of all Money magazine subscribers that made money in the previous year from their investments is between 0.6904 and 0.8218

Step-by-step explanation:

The confidence interval gives a range of values for which a population proportion will fall based on a given level of confidence, in this case it is 95%. This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.

Answer:

area of a rectangle is l×w ask 5 ×10 =50

Answer:

The answer is "0.052 and 0.056".

Step-by-step explanation:

For option 1:

Your daughter's opportunity (in sport) (when a person only wins once)

[tex]\to \frac{1}{39}+\frac{1}{38}\\\\ \to \frac{38+39}{1,482} \\\\\to \frac{38+39}{1,482} \\\\\to 0.052[/tex]

For option 2:

Your daughter would win a chance (in sport) [tex]= \frac{1}{18} = 0.056[/tex]

So a little better, the second option. The rationale is that there are fewer girls than boys so if a lottery in a smaller group is awarded you are more likely to win.

Answer:

(2, 4)

Step-by-step explanation:

y = x + 2

3x + y = 10

3x + (x + 2) = 10

4x + 2 = 10

4x = 8

x = 2

y = (2) + 2

y = 4

Step-by-step explanation:

3x + y = 10

substituting the value of y = x + 2

=>3x + x+2 = 10

=>4x= 10-2

=>4x= 8

=>x= 8/4

=>x= 2

And, y= 2+2 = 4

Answer:

The median of this problem is 9

Answer:

ok so so here are the numbers equal to 6

1,5

5,1

2,4

4,2

3,3

so five options and there are 36 possible outcomes(6*6)

so 5/36 or 0.14

Hope This Helps!!!

The solution is,  the probability that the sum of the two dice is greater than or equal to six is 0.14.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we get,

You roll two six-sided dice numbered from one through six.

so here are the numbers equal to 6

1,5

5,1

2,4

4,2

3,3

so five options and there are 36 possible outcomes(6*6)

we get, sample space = 36

favorable outcome = 5

probability = 5/36

so 5/36 or 0.14

Step-by-step explanation:

area of a circular pool=πr^2

=3.14*(2)^2

=3.14*4

=12.56 m^2

Answer:

12.56 inches squared

Step-by-step explanation:

Radius= 2

Diameter= 4 (double the radius)

Pi= 3.14

Formula for finding area of circle= Pi x r squared

2 x 2= 4 (to find diameter)

4 x 3.14= 12.56

Answer:

x = 2 , y = 4.

(2,4)

Step-by-step explanation:

Simultaneous equation:

2x - y = 10    E1

y = [tex]-\frac{1}{2}x[/tex] + 5    E2

Substitute equation 2 into equation 1 for the y value.

2x -  [tex]-\frac{1}{2}x[/tex] + 5  = 10

2x -  [tex]-\frac{1}{2}x[/tex] = 5

2x +  [tex]\frac{1}{2}x[/tex] = 5

[tex]\frac{5}{2} x[/tex] = 5

x = 2

Substitute the x value  into  equation 2.

y = [tex]-\frac{1}{2}2[/tex] + 5

y = -1 + 5

y = 4

Answer:

Around 0.73% of adults in the USA have stage 2 high blood pressure

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 121 and standard deviation of 16.

This means that [tex]\mu = 121, \sigma = 16[/tex]

Around what percentage of adults in the USA have stage 2 high blood pressure

The proportion is 1 subtracted by the p-value of Z when X = 160. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{160 - 121}{16}[/tex]

[tex]Z = 2.44[/tex]

[tex]Z = 2.44[/tex] has a p-value of 0.9927.

1 - 0.9927 = 0.0073

0.0073*100% = 0.73%

Around 0.73% of adults in the USA have stage 2 high blood pressure
