Answer:
Step-by-step explanation:
Let the smallest number = x
The next number will be x + 1
x + x + 1 = 5
2x + 1 = 5 This is likely the answer to the question although it could be the equation above.
Answer:
A≈16.65
Step-by-step explanation:
h Height 3
AB Base area 4
4 3/4 equals 19/4ths so the correct answer would be 19 burgers
Answer:
f(x)=3x^2+2x-10 if x=2
f(x)=3(2)^2+2(2)-10
f(x)=3(4)+2(2)-10
f(x)=12+4-10
f(x)=16-10
f(x)=6
g(x)=3x-3 if g(x)=2
g(x)=3(2)-3
g(x)=6-3 =3
Step-by-step explanation:
<u>f</u><u>(</u><u>x</u><u>)</u>
- replace x by 2
- do exponent
- distribute the brackets
- do addition and subtraction
g(x)
- replace x by 2
- distribute the bracket
- do subtraction
Answer:
The test statistic would be given by:
(1)
And replacing we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
t would represent the statistic
System of hypothesis
We want to test if the true mean is lower than 25, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The test statistic would be given by:
(1)
And replacing we got:
