Momentum = mass * velocity
50 meters in 5 seconds = 50/5 = 10 m / second
Required momentum = 200*10 = 2,000
I cant remember how to write the units for this.
The GCF here is 2
2(z - 11z + 24)
i assume your question is wrong.. or you printed it inaccurately
because the 1st term should indicate the highest exponent however the 1st and 2nd terms are having the same exponent!!
Answer:
Probability of having at least 4 Girls
= 0.6875
Step-by-step explanation:
Probability of having at least 4 Girls is 1-probability of having exactly 3 girls
Total number of children= 5 = N
Probability of having a girl p = 0.5
Probability of not having a girl q= 0.5
X= 3
Probability of at least 4 girls is given by
Probability= NCX(p)^x(q)^(N-x)
Probability = 5C3(0.5)^3(0.5)^(5-3)
Probability = 5C3(0.5)^3(0.5)^2
Probability= 5!/3!2!(0.5)^3(0.5)^2
Probability= 10(0.125)(0.25)
Probability= 0.3125
Probability of having at least 4 Girls
= 1- 0.3125
= 0.6875
Answer:
1 X 16 and 8 X2
Step-by-step explanation:
1 X 16 = 16
2 X 8 = 16
3 X nothing = 16
4 X 4 = 16
5 X nothing = 16
6 X nothing = 16
7 X nothing = 16
8 X 2 = 16
etc.
So,
Her average so far is the sum of the five scores divided by the number of tests she has taken so far.
(87 + 81 + 85 + 90 + 78)/5 = 84.2
(87 + 81 + 85 + 90 + 78)/5 < 85 :(
She will not get into that college if she doesn't increase her average on the last test.
85 - 84.2 = 0.8
0.8(5) = 4.0
On her last test, she needs to score 4 points higher than her current average in order to get into the college.
84.2 + 4 = 88.2
Jessica needs to score at least 88.2 on her last test.
