For this case we have to:
n: Represents the weight of Mary in Kg.
If your sister weighs 15 kg less we have:
Where "y" represents the weight of his sister in kg.
To find how many times Mary is heavier than her sister, we must divide Mary's weight by her sister's weight.
We have then:
Answer:
Mary is times heavier than her sister.
Answer:
11x^2-8x-14
Step-by-step explanation:
(2x^2- 8x– 6)+(9x^2-8) = 11x^2-8x-14
Answer:
Option C. 0.05x+0.10(x+6)=1.35
Step-by-step explanation:
Remember that
1 nickel=$0.05
1 dime=$0.10
Let
x-----> the number of nickels
y----> the number of dimes
we know that
0.05x+0.10y=1.35 -----> equation A
y=x+6 ----> equation B
substitute equation B in equation A and solve for x
0.05x+0.10(x+6)=1.35
Angle J is given as a 45
Angle L is given as a 45
Angle K is 90 (it says it’s a right triangle so it has to have a 90 degree angle and 180-45-45=90)
The JK leg given equals 6.92
Leg LK equals 6.92
6.92^2 +6.92^2= the last leg which is 95.77^2
95.77^2=9.78
Leg JL equals 9.78
Answer: the probability of selling exactly 6 tickets with popcorn coupons out of 10 total tickets is 0.23
Step-by-step explanation:
We would assume a binomial distribution for the number of tickets sold to a movie with and without popcorn coupon. The formula is expressed as
P(x = r) = nCr × p^r × q^(n - r)
Where
x represent the number of successes.
p represents the probability of success.
q = (1 - r) represents the probability of failure.
n represents the number of trials or sample.
From the information given,
p = 54.4% = 54.4/100 = 0.544
q = 1 - p = 1 - 0.544
q = 0.456
n = 10
x = r = 6
Therefore,
P(x = 6) = 10C6 × 0.544^6 × 0.456^(10 - 6)
P(x = 6) = 210 × 0.0259 × 0.043
P(x = 6) = 0.23
