All you have to do is substitute the numbers in the variables so it would be
14/1-7+4(5)
=14-7+4(5)
But you have to do pemdas so you would start with multiplication so it would be
=14-7+20
=7+20
=27
<h2>
Answer: (−∞,∞)</h2>
Step-by-step explanation:
Answer:
We Do not have enough evidence
Step-by-step explanation:
H0 : σ² ≤ 1.1
H0 : σ² > 1.1
The test statistic (X²) :
χ² = [(n - 1) × s²] ÷ σ²
n = sample size, = 20
s² = 1.6
σ² = 1.1
α = 0.01
χ² = (19 * 1.6) / 1.1
χ² = 27.64
Pvalue :
Using the Pvalue from Chisquare score calculator ; χ² = 27.64 ; df = 19
Pvalue = 0.091
If Pvalue < α ; Reject H0
0.091 > 0.01
Hence, Pvalue > α ; Thus we fail to reject H0.
We thus conclude that, we do not have enough evidence to support the claim that her standard deviation is greater than the target.
Answer:5n+6
Step-by-step explanation :an=a1+d(n-1)
=1+(-5)(n-1) or 1+-5n+5
an=-5n+6
Answer:
The distance from the burger shop to the boardwalk is 7 miles.
Step-by-step explanation:
Steve follows the following sequence:
Home -> Burger shop -> Boardwalk
The total distance is 15 miles.
Steve's house to the burger shop is 8 miles. What is the distance from the burger shop to the boardwalk?
Home -> Burger shop: 8 miles
Burger shop -> Boardwalk: x miles
Total: 15 miles
8 + x = 15
x = 7
The distance from the burger shop to the boardwalk is 7 miles.
