The answers are below
Step-by-step explanation:
1. H0: rho = 0
H1: rho not equal to 0
2. I will add the scatter plot as an attachment
3. ΣX = 523,
ΣY = 1055
ΣX² = 46023
ΣY²= 430407
ΣXY = 111448
n = 7
The correlation coefficient r =
r = 7(111448)-(523)(1055)/√7(46023)-(523)² × √7(430407)-(1055)²
r = 780136-551765/√322161-273529√3012849-1113025
= 228371/220.53*1378.34
= 228371/303965.32
r = 0.751
4. Test statistics
t = r√n-2/√1-r²
= 0.751√5/√0.5640
= 1.679/0.660
= 2.543
5. P value
Degrees of freedom n-2 = 5
T dist(2.543,5,2)
The p value is less than 0.05 so we reject null hypothesis. There is enough evidence to show a linear correlation between budgets and gross receipts.
Answer:
0.44
Step-by-step explanation:
P(white/pickup)
= P(white&pickup)/P(pickup)
= 0.04/0.09
= 4/9
0.4444

The missing values in the diagram given that figure ABCD is a dilation of figure KLMN, are:
AB = 4
LM = 20
∠B = 98.87°
∠N = 141.87°
<h3>What is Dilation?</h3>
Dilation is a form of transformation whereby a new figure is formed by enlarging or reducing an original figure by a scale factor. After dilation, the corresponding sides of both figures are proportional, while the corresponding angles of both figures are congruent to each other.
Find AB:
AB/KL = DC/NM
Plug in the values
AB/10 = 4/10
AB(10) = 4(10)
AB = 40/10
AB = 4
Find LM:
BC/LM = DC/NM
Plug in the values
8/LM = 4/10
8(10) = 4(LM)
LM = 80/4
LM = 20
∠B = ∠L = 98.87°
∠N = ∠D = 141.87°
