Answer:
Unusual
Step-by-step explanation:
we know that
The z-score is a measure of how close the given data point is to the mean of the values given with the standard deviation
so
if its z-score is greater than or equal to -2, or less than or equal to 2., then the data value is considered ordinary
if its z-score is less than -2 or greater than 2, then the data value is considered unusual
The answer is the third option.
The explanation is shown below:
1. You must keep on mind the information given in the exercise:
- She bough 3 pounds of coffee.
- She bought 2 pounds of chocolate.
- She spent a total of $24.
2. Therefore, you can call the price per pound of coffee 
and the price per pound of chocolate 
.
3. When you multiply 3 pounds by the price per pound of coffee, you obtain the amount of money she spent for 3 pounds. When you multiply 2 pounds by the price per pound of chocolate, you obtain the amount of money she spent for 2 pounds. If you add both amounts, you obtain the total spent, which was $24.
4. Therefore, you can express this as following:
Answer:
TRUE
Step-by-step explanation:
We are given 2 triangles, ∆ABC and ∆DEF.
For the two trinagles to be considered similar, both must have their set of corresponding angles congruent to each other. That is, their corresponding angles are equal.
From the information given, the following are the set of corresponding angles:
<B = <E = 31°
<B = <D = 90°
<C = <F = 59° [180 - (90+31)]
The corresponding angles of both triangles are congruent. Therefore, it is guaranteed that ∆ABC is similar to ∆DEF (∆ABC ~ DEF).
Answer: It would take 40 minutes to mow a lawn with a mower containing 12-inch wide blades.
Step-by-step explanation:
We can combine x + x and get 2x. So we have:
8x - 2y + 2x. Therefore 10x - 2y is equivalent.
