Answer:
$44.45
Step-by-step explanation:
5 bushels of oranges is $31.75 so 1 bushel is 31.75/5 = 6.35
7 bushels of orange is $6.35 x 7 = $44.45
Answer:
a) Yes b) No
Step-by-step explanation:
Given that the p value for a two-sided test of the null hypothesis H0: μ = 10
is 0.06
a)
Hence we accept null hypothesis
This implies that 10 will be within the confidence interval of 95%
b) If confidence level = 90%
So we have to reject null hypothesis.
So we do not have 10 in the confidence interval
The reason is the lower the confidence level, the narrower the confidence interval. In this case, 10 has gone outside the narrower interval hence we get this.
The element is remaining after 18 minutes with the rate of decaying of 26.8 % is 2.99 grams.
<h3>What is the percentage?</h3>
The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
An element with a mass of 820 grams decays by 26. 8% per minute.
Then the mass remaining after one minute will be
Remaining = 100 - 26.8
Remaining = 73.2 %
The element is remaining after 18 minutes will be
Mass = 820 × (0.732)¹⁸
Mass = 820 × 0.00364
Mass = 2.985
Mass ≈ 2.99
The element is remaining after 18 minutes is 2.99 grams.
