1) Find the Highest common factor (HCF) of 28 and 63 by expressing them as prime factors.

28=4*7=2*2*7
63=9*7=3*3*7
The number that occurs in both is the HCF (if the same number appears twice or more in <em>both</em> put it to the power of x where x is the number of occurrences)

In this we can see that the HCF is 7, therefore you can divide both the numbers by 7.

28/63 ----> 4/9
4=2*2
9=3*3

There are no matching numbers for 4 and 9 therefore that is the fraction in its simplest form.

Answer:

Expected value for the event = $148

Step-by-step explanation:

Expected value (EV) = Σ(Px*x)

Pr(rainy day) = 0.01

Px for rainy day = 0.01

Pr (sunny day) = 1-0.01 = 0.99

Px for sunny day = 0.99

If it's sunny, income = $200

Cost of preparation = $50

x for sunny day = 200-50 = 150

If it's rainy, income = $0

Cost of preparation = $50

x for sunny day = 0-50 = -50

EV =Σ(Px * x)

EV = (0.99*150)+(0.01*-50)

EV = 148.5+(-0.5) = 148.5-0.5

Expected value for the event = $148

An airplane flies 105 miles per half an hour. How far can it fly in 1.25 hours at the same speed. Brainliest for correct answer.

marin [14]

262.5 should be the correct answer though. 105/30=3.5 so the plane is approximately traveling at 3.5 miles per minute. 3.5x60= 210 so at an hour it has traveled 210 miles. Then we must find .25 of an hour which is 15 minutes. 15x 3.5=52.5. Add both the hour value and the .25 of an hour value together and it is 262.5 miles.

Step-by-step explanation:

The inequality Equation =

42 + 5x < 60

To stay within her budget of less than $60 she must use less than 3.6 Gigabytes

Step-by-step explanation:

Under her cell phone plan, Brooklyn pays a flat cost of $42 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.

Let the number of gigabytes = x

Under $60 means less than $60

The inequality =

$42 + $5×x < $60

42 + 5x < 60

Solving for x

42 + 5x < 60

5x < 60 - 42

5x < 18

x < 18/5

x < 3.6 Giga bytes

Hence, to stay within her budget of less than $60 she must use less than 3.6 Gigabytes
