Answer:
The situation that says Sasha sells a scarf for $10.00 and xjackets for 25.75 each
Step-by-step explanation:
We know thatt she is only selling one scarf for $10.00 and we know we are multiplying X jackets times 25.75
so 25.75x + 10
Answer:
134 hamburgers sold on Sunday
Step-by-step explanation:
x+3x=536
4x=536
4x/4=x, 536/4=134
x=134

Step-by-step explanation:
Given the following :
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
STEP 1:
Stress score in general executive (s1)
Stress score in exercising executive (s2)
Null : s1 = s2
Alternative : s1 < s2
STEP 2:
Shape of distribution = normal
Population mean (μ) = 2.55
Population standard deviation (σ) = 0.5
Sample size (n) = 30
Sample mean (x) = 2.76
α = 0.05
Decision rule :
α = 0.05 which corresponds to a t score (t0) ;
df = n - 1 = 30 - 1= 30 at 0.05 = 1.699
If :
(Test statistic (t) > t0) ; reject the Null
(right tailed test)
Test statistic (t) :
(x - μ) / (σ/√n)
(2.76 - 2.55) / (0.5/√30)
0.21 / 0.0913
= 2.30
t > t0
2.30 > 1.699
t is more extreme than t0
Hence, reject the null at α = 0.05
These two events are complimentary. So P(not rain)=1-P(will rain)
So, 75% is my guess
