Answer:
<h2>13.7≤
≤14.7</h2>
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as shown;
CI = xbar ± Z(б/√n)
xbar is the sample mean
Z is the value at 95% confidence interval
б is the standard deviation of the sample
n is the number of samples
Given xbar = 14.2, Z at 95% CI = 1.96, б = 0.70 and n = 9
Substituting this values into the formula;
CI = 14.2 ± 1.96(0.70/√9)
CI = 14.2 ± 1.96(0.70/3)
CI = 14.2 ± 1.96(0.2333)
CI = 14.2 ± 0.4573
CI = (14.2-0.4573, 14.2+0.4573)
CI = (13.7427, 14.6537)
Hence, the 95% confidence interval of the true mean is within the range
13.7≤≤14.7 (to 1 decimal place).
Answer:
Yes, The given sequence is Arithmetic with common difference is 7.
Step-by-step explanation:
The given sequence is Arithmetic Sequence.
Generally, we study about two types of sequences which are:
Arithmetic Sequence is a sequence in which every two neighbor digits have equal distances.
Geometric Sequence is the sequence in which every digit is the same multiplier of its previous digit.
The given sequence is: 13, 20, 27, 34,...
Here, First term(a) = 13, Second term(b) = 20
Common difference (d) = b - a = 20 - 13 = 7
Hence, Common difference is 7.
Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:
2 = ⅙[4] + b
⅔
_______________________________________________
1 = ⅙[−2] + b
−⅓
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

Answer:
80 ft^2 of paint would be needed
Step-by-step explanation:
Since we do not consider the roof, all we need do is to calculate the area of the shape without the roof side
So without the roof, we have 4 rectangles
we have 4 ft by 4 ft on both sides
Then 6 ft by 4 ft on the other two sides
mathematically, the area of a rectangle is the product of its sides
so, we have the total area as;
2(6 * 4) + 2(4 * 4)
= 2(24) + 2(16)
= 48 + 32
= 80 ft^2
