Using PEMDAS, You know that you have to multiply first so 3*2 is 6. Than you have to add 6+4 which gives you 10... So there for 10 is your answer....
Answer:
u
Step-by-step explanation:
Solution:-
- Claim : pizza shop deliver in 30 minutes or less or it is free.
- Alternate : People who live in on opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.
- Sample size taken n = 50 > 30
- The sample mean = 32 mins
- The appropriate symbol for sample mean used in test statistics is (u).
Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.
Let X be the height of a randomly selected adult giraffe.
X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 
d) 
e) 
f) 75th percentile for z is 0.675
I don't know 5 and 7 it's to complicated for me plus I haven't learned how do those kind
6)7/3 (c+3)=1/3-c
7/3c+7=1/3-c
3×7/3c+3×7=3×1/3-3c
7c+3c=1-21
10c=-20
c=-2
Solve using the foil method (first, outside, inside, last).
(m + 5)(m - 3)
Your steps using foil should look like:
- m * m
- m * -3
- 5 * m
- 5 * -3
After multiplying, rewrite your expression.
m² - 3m + 5m - 15
The last step to simplifying this expression is to combine like terms, which are -3m + 5m.
<h3>m² + 2m - 15</h3>
