Answer:
YES ALL THE CONDITIONS HAVE BEEN MET
Step-by-step explanation:
H o:mu1=mu2
Ha:mu1 not = mu2
n1=30
n2=30
large samples follows normal distribution
and they are independent samples
we can conduct t test for 2 groups we can ignore that condition randomness
YES ALL THE CONDITIONS HAVE BEEN MET
If it was 25% off, then she paid 75% for it
75% of the original price is 170
0.75x = 170
x = 170 / 0.75
x = 226.67 <== original price
<span>y=7x
x = -1 y = -7
x = 0 y = 0
x = 1 y = 7</span>
Step-by-step explanation:
7.4÷4= 1.85
1 jar weighs 1.85 pounds
1.85×24= 44.4 pounds
another way:
7.4x6= 44.4pounds
Answer:
sin θ = 24/25.
Step-by-step explanation:
Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.
So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)
= sqrt 576
= 24 .
Therefore sin θ = 24/25.
