I did a quick search and the web said there are 12 categories! So none of the choices...
"Excel groups functions into 12 categories: Compatibility, Cube, Database, Date and Time, Engineering,Financial, Information, Logical, Lookup & Reference, Math & Trigonometry, Statistical and Text."
There's one other category called "Web functions", mentioned in Microsoft's website.
So the answer is 13.
Answer:
lower limit : 36.44
upper limit : 39.56
Step-by-step explanation:
Given :
s = 9
n = 90
x = 38.9
Alpha, α = 0.10
∴ 
The confidence interval is :
Therefore,
lower limit : 36.44
upper limit : 39.56
Answer:
25
Step-by-step explanation:
To find the missing side (in this case, the longest one/hypotenuse), we can use the equation a^2 + b^2 = c^2. By substituting out the variables, we get 7^2 + 24^2 = c^2; this can be simplified to 49 + 576 = c^2. Add, and then we know that 625 = c^2. If c squared is 625, we need to find the square root of 625, which is 25.
Answer:
d =2
Step-by-step explanation:
6d+8=14+3d
Subtract 3d from each side
6d-3d+8=14+3d-3d
3d +8 = 14
Subtract 8 from each side
3d +8-8 = 14-8
3d =6
Divide by 3
3d/3 = 6/3
d =2
Answer:
D is the correct answer
Step-by-step explanation:
Let the age of Holly is x years. Now from the statements of the question we will form the equations.
Sue was born three years before Holly.
Sue = Holly + 3 = x + 3------(1)
Jeremy = Sue + 5
From equation (1)
Jeremy = (x + 3) + 5 = x + 8------(2)
Now statement says the product of Sue's age and Jeremy's age is at most 150.
Sue × Jeremy ≤ 150
(x + 3)(x + 8) ≤ 150
x² + 11x + 24 ≤ 150
Therefore inequality x² + 11x + 24 ≤ 150 can be used to find the age of each sibling.
HAVE AN AMAZING DAY, GLAD TO HELP. ^.^
