<h3>Answer: 14</h3>
========================================================
Explanation:
At 95% confidence, the z critical value is roughly z = 1.960
The population standard deviation is given to be sigma = 3.7
The error is E = 2 since we want to be within 2 inches of the population mean mu
The min sample size needed is:
n = (z*sigma/E)^2
n = (1.960*3.7/2)^2
n = 13.147876
n = 14
We always round up to the nearest whole number to ensure that we clear the hurdle (otherwise, the sample is too small). It doesn't matter that we're closer to 13 than to 14.
Answer:
Step-by-step explanation:
so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10
i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive
so we have 1x + 6 + -6x + 10
we can add 6 and 10 and 1x and -6x make an end result of
-5x + 16
(or the other way since it is addition)
Answer:
16
Step-by-step explanation:
8^(4/3)
replace 8 with 2^3
2^3 ^ (4/3)
2 ^ (3*4/3)
2^ 4
16
x^3-2x^2+9x-2
To solve this, arrange the terms in descending order by their exponents
Answer:
Ok for the 1st and 2nd paragraph, each person will need to pay 20 dollars each. For the 3rd paragraph, you could say your favorite restaurant is McDonalds. For you, you could have a strawberry milkshake, medium fries, and a Big Mac. For your second friend, they could have a coca cola, a salad, and large fries. For your third friend, they could have a lemonade, lettuce hamburger, and chocolate ice cream. For your fourth friend, they could have a Oreo Mc flurry, chicken nuggets, and small fries.
Restaurant name: McDonalds
Price: 59.99/60.00
Cost of each persons order: you pick
Each person should leave 5 dollars as a tip.
The total including tip: 79.99/80.00
Each person will pay 15.00
I dont know the last one sorry
