Answer:
3*(5*x-7)-(15*x-21)=0
Step-by-step explanation:
3 • (5x - 7) - (15x - 21) = 0
Step 2 :
Equation at the end of step 2 :
0 = 0
Step 3 :
Equations which are always true :
Hey!
If 112 people are getting cake and 5/8 are getting chocolate, that means the remaining will get chocolate.
8/8 - 5/8 = 3/8
3/8 are getting chocolate. You have to find 3/8 of 112.
3/8 × 112 = 336/8 = 42
42 people are getting carrot cake

The probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754
<h3>What is Probability ?</h3>
Probability is defined as the likeliness of an event to happen.
It has a range of 0 to 1.
It is given that
Pete, a professional bowler, is unhappy with any game below 200
80% of his games exceed this score.
the probability that Pete exceeds 200 in at least 9 of his next 10 games is given by
P( 9/10 > 200) +P(10/10>200)
The binomial experiment consists of n trial out of it x is success.

Here p = 0.8
For 9/10 matches

For (10/10 >200)

Therefore the probability that Pete exceeds 200 in at least 9 of his next 10 games is 0.268+0.1074 = 0.3754.

For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 200 * (1.10) ^ (t)
For 3 years we have:
y = 200 * (1.10) ^ (3)
y = 266.2
Rounding off we have:
y = 266
Answer:
there will be 266 squirrels in the population after 3 years
Yes, Harrison's way doesn't work because 5/5 = 1 and 4 1's don't make 22/5
