Answer:

2/91.

Step-by-step explanation:

There are 15 marbles in the bag.

Prob(First draw is red) = 5/15 = 1/3.

Prob(Second draw is red) = 4/14 = 2/7.

Prob(Third draw is red) = 3/13.

So probability that all 3 are red = .1/3 * 2/7 * 3/13

= 6/273

= 2/91.

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

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:

it is the center of the inscribed circle

Answer:

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

(to find area)

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.

Answer:

$33.10

Step-by-step explanation:

$28.96 + $2.56 = $31.52

$31.52 * .05 = $1.576 (round up) $1.58

$31.52 + $1.58 = $33.10

Answer:

Step-by-step explanation:

Total without sales tax

Snorkel  =         28.96

Ear Plugs            2.56

Total                  31.52

Sales tax = 5% of Total  = 5/100 *31.52

Sales tax = 1.58 Rounded.

Total purchase = 33.10

Answer:

x=25

Step-by-step explanation:

The angles 126 and (5x+1) are equal. The equation that is used is 5x+1=126.

To solve the equation, subtract 1 from both sides

5x+1-1=5x     126-1=125.

Simplify the equation. 5x=125

Divide both sides by 5.   5x/5=x     125/5=25

You would get x=25 eventually.

Answer:

  (a)  5/6

Step-by-step explanation:

Positive numbers are greater than negative ones.

Fractions with the same denominator are greater if their numerator is greater.

All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...

  5/6 > 1/6 > -1/6 > -5/6

The fraction with the greatest value is 5/6.
