Answer: Width of 32 inches high school flag = 72 inches.

Height of 48 inches wide school flag = 21.3 inches

Step-by-step explanation:

Given : Washington Middle school's school flag has a height -width ratio of 12:27.                                         (1)

Let x be the width of 32 inches high school flag.

Then height -width ratio = \dfrac{32}{h}             (2)

From (1) and (2) , we have

\dfrac{32}{x}=\dfrac{12}{27}\\\\\Rightarrow\ x=\dfrac{27\times32}{12}=72    

Hence, width of 32 inches high school flag = 72 inches.

Let h be the height of 48 inches wide school flag.

Then height -width ratio = \dfrac{h}{48}             (3)

From (1) and (3) , we have

\dfrac{h}{48}=\dfrac{12}{27}\\\\\Rightarrow\ h=\dfrac{12\times48}{27}=21.3333333333\approx21.3    

Hence, height of 48 inches wide school flag = 21.3 inches

Twelve percent of the population is left handed. Approximate the probability that there are at least 20 left-handers in a school
DochEvi [55]

Answer:

Step-by-step explanation:

We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).

p = 12/100 = 0.12

number of success, x = 20

n = 200

the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)

From the binomial probability calculator,

P(x ≥ 20) = 0.84

This recipe makes 30 shortbread fingers.
siniylev [52]

Answer:

24 g butter

12 g sugar

36 g flour

Step-by-step explanation:

The recipe makes 30 shortbread fingers.

She wants to make 6 fingers.

6/30 = 1/5

She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.

Divide each amount by 5.

Recipe:

Makes 30           30/5 = 6               Makes 6  

120 g butter       120/5 = 24            24 g butter

60 g sugar         60/5 = 12              12 g sugar  

180 g flour​         180/5 = 36            36 g flour

A basketball player scored 24 times during one game. She scored a total of 41 points, two for each two-point shots and one for e
PilotLPTM [1.2K]

Answer:

<em>Number of points shoot, x=17</em>

<em>Number of </em><em>free</em><em> </em><em>shoot</em><em>,</em><em> </em><em>y</em><em>=</em><em>7</em>

Step-by-step explanation:

Let us consider,

point shoot as x

free shoot as y.

Question say " A basketball player scored 24 times during one game "

Therefore, Number of point shoot + Number of free shoot = 24

Numerically we get,

x+y=24

Now, Free shoot gives one point and point shoot gives two points.

She scored total of 41 points.

2x+y=41

we get two equations

x+y=24

2x+y=41

By solving above linear equations...

we can write, y=24-x

replacing y value in 2x+y=41

2x+24-x=41

<em>x=17</em>

To find value of y, replace x vaule in any equation

say, x+y=24

17+y=24

<em>y=7</em>

Thus, x=17 and y=7

Number of points shoot, x=17

Number of free shoot, y=7
