Choice 4, (x,y) (2x,y) I think is the answer, because when you multiply 2 by x, you're expanding the shape
Answer:
1.y=3x+1
2.y=1/3x+2
3.y=-2x+5
4.y=4x
5.y=4x-4
6.y=-2x-5
Step-by-step explanation:
(i)
y=mx+c
10=(m)3+1
10=3m+1
10-1=3m
m =3
y=3x+1
And so on...
Answer: f) None of the above
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.6ft
Standard deviation r = 1.0ft
Number of samples n = 27
Confidence interval = 90%
z(at 90% confidence) = 1.645
Substituting the values we have;
5.6+/-1.645(1.0/√27)
5.6+/-1.645(0.192)
5.6+/-0.317 ft
= ( 5.283, 5.917)
Therefore at 90% confidence interval (a,b) = ( 5.283, 5.917)
Alright, lets get started.
Suppose Francine made number of baskets = x
As given in question, Jane scored 4 times as many as Francine.
Means Jane has scored number of baskets will be = 4x
Jane and Francine made 20 baskets together, means
Dividing 5 in both sides
x = 4
Means Francine made number of baskets = 4
Hence Jane made number of baskets =

Hi there
To find The interest rate the formula is
R=I÷pt
r interest rate?
I interest earned 622.5
P principle 12450
T time 1 year
So
R=622.5÷(12,450×1)
R=0.05×100=5%
Hope it helps
