Answer:
Step-by-step explanation:
we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)
so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.
the whole equation would be: 24+70+42= 136
so your answer would be B: 136.
hope this helps :)
Answer:
In a one-way ANOVA, the 
is calculated by taking the squared difference between each person and their specific groups mean, while the 
is calculated by taking the squared difference between each group and the grand mean.
Step-by-step explanation:
The one-way analysis of variance (ANOVA) is used "to determine whether there are any statistically significant differences between the means of two or more independent groups".
The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean.
If we assume that we have p groups and each gtoup have a size 
then we have different sources of variation, the formulas related to the sum of squares are:
A measure of total variation.
A measure of variation between each group and the grand mean.
A measure of variation between each person and their specific groups mean.
The slope is 5.
Distribute the 5 and add the 3
Answer:
106250
Step-by-step explanation:
Ok so we know that in the first quarter the company sold 125000 units to people. But then suddenly they start losing 5%. Since we are told there are 3 quarters, we would have to do 5% plus 5% plus 5%, which amounts to 15% total lost in the three quarters. What we do now is we technically subtract that to 125000, so the equation would be 125000 minus 15%, and when you either use a calculator to help or your own mind, you get 106250 units sold.
Three times the difference of a number and four.
or
Three times the quantity of four less than a number n.
