Answer:
x = 5
Step-by-step explanation:
The figure shows that angles EAF and FAL are congruent, so we can equate their measures and solve for x.
4x + 10 = 3x + 15
Subtract 3x from both sides. Subtract 10 from both sides.
x = 5
Answer : 59%
Step-by-step explanation:
Answer:
We cannot infer at the 10% significance level that the assumption of ski centers is wrong
Step-by-step explanation:
The null hypothesis for this question can be stated as
Null hypothesis H0: =4
Alternate hypothesis Ha:
The test is two tailed
Standard Deviation –
= 2
z=(4.84-4)/(2/sqrt(63))
=3.33
Z(0.1/2)=1.645 is less than Z =3.334
Hence, we will reject H0
Hence, the average growth skier ski’s four times a year is not true
Answer: B. 72ᴼ alternate exterior angles theorem
Step-by-step explanation:
Alternate exterior angles because they’re angles on the outside of the transversal.
Alternate exterior angles are also congruent to each other, so that’s why 2 is congruent to 72ᴼ
Answer:
ab • (11a + b + 1) If its not im really sorry
Step-by-step explanation:
STEP one
(((((3•(a2))•b)+5ab)-4ab)+(a•(b2)))+(23a2•b)
STEP Two
((((3a2 • b) + 5ab) - 4ab) + ab2) + 23a2b
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
11a2b + ab2 + ab = ab • (11a + b + 1)
