Answer:
x=-5
Step-by-step explanation:
First set the values equal to each other;
5x-10=3x-20
Add 10 to both sides;
5x-10+10=3x-20+10
Simplify;
5x=3x-10
Subtract 3x from both sides;
5x-3x=3x-10-3x
Simplify;
2x=-10
Divide both sides by 2;
2x/2=-10/2
Simplify 2x/2;
2/2=1
=x
Simplify -10/2;
Apply the fraction rule;
=-10/2
Divide the numbers ; 10/2
x=-5
Answer:
Yes
Step-by-step explanation:
The value x = 42 is a solution to the equation 7 = x/6.
Answer:
b = 64°
2b = 128°
Step-by-step explanation:
use (n-2)×180 to find the total number of degrees inside a polygon where 'n' equals number of sides
hexagon has 6 sides; (6-2)×180 = 720°
528 + 3b = 720
3b = 192
b = 64
Answer:
12!
Step-by-step explanation:
Answer:
Step-by-step explanation:
First set up hypotheses as
(Right tailed test at 5% significance level)
Mean diff = 716.6-703.1=13.5
s = 80.1: So std error = s/sqrt n = 13.539
Since population std dev not known t test can be used
n = 35: df=35-1 =34
Test statistic =Mean diff/std error =0.9971
p value = 0.16288>0.05
Since p value >our alpha accept null hypotheis
Conclusion:
There is no statistical evidence to claim that high-income individuals have higher credit scores
