Answer:
No because 3/4 is equal to 0.75 and 0.75 is not equal to 0.34
Step-by-step explanation:
Answer:
After 5 hours
Step-by-step explanation:
Given that Rachel can make 3 bracelets in an hour.
Let y be the no of bracelets and x no of hours.
Then equation for Rachael would be y = 3x ... i
Oliver is having initially 5 completed bracelets and every hour he would make 2 new bracelets
Hence equation would be
y = 2x+5 ... ii
Our question is why both will be equal
y would be equal in both if 3x=2x+5
Or x=5
After 5 hours form the start, both will have same number of bracelets.
Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you
Answer:
46$
Step-by-step explanation:
20+20=40, 5% of 40=2, 42, +4, 46. (the 4 comes from the 10%)
we are given
To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant
now, we can compare with
and then we can find a , b and c
now, we can find D
It has two x-intercepts
so,
now, we can solve for m
