It could be 2+1 beacuse it says there are twice as many
113/8
14 x 8 = 112
112 + 1 = 113
Answer:
We conclude that cheddar popcorn weighed less than 5.5 ounces.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ =5.5 ounces
Sample mean, = 5.23 ounces
Sample size, n = 64
Alpha, α = 0.05
Sample standard deviation, σ = 0.24 ounce.
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, we conclude that cheddar popcorn weighed less than 5.5 ounces.
Answer:
B = 42.7 degrees, C = 102.3 degrees and c = 18.7.
Step-by-step explanation:
We use the Sine Rule:
a / sin A = b / sin B
11 / sin 35 = 13 / sin B
11 sin B = 13 sin 35
sin B = 13 sin 35 / 11 = 0.677863
B = 42.7 degrees.
So C = 180 - 42.7 - 35
= 102.3 degrees.
c / sin 102.3 = 11 / sin 35
c = 11 sin 102.3 / sin 35
= 18.7.
