Answer:
hola
Step-by-step explanation:
in spanish plissssssssss
The answer is 60 because it can be divided by all three numbers. Next time you come across problems such as these, I suggest you start by looking at the number that makes sense logically. For instance, numbers that have 5 as a factor must end with 0 or 5, narrowing the options down to 65 and 60. Since 65 is an odd number, the answer can only be 60.
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:
None
Step-by-step explanation:
None of these could be correct.
Number 1 is 15 (50-35)
number 2 is 24 (24-24) (0+24)
number 3 is 90.
if anything the best choice would be 2
Answer:
Equation: x + (x+ 1) = 67
Step-by-step explanation:
We want to find two consecutive integers.
Let them be labeled as x and x + 1
We want x + (x + 1) = 67
x is the smaller number
x + 1 is the largest
We can solve for x.
x + (x + 1) = 2x + 1 = 67
2x = 66
x = 33
The largest integer is 34
