Answer:
1/3
Step-by-step explanation:
Answer:
x = 2, x = 4
Step-by-step explanation:
The equation y = 10 - 9x is a linear equation and the value of either y or x can be found by substituting the given values of either y or x.
given that y = -8, and substituting this into equation y = 10 - 9x,
we have, -8 = 10 - 9x
10 + 8 = 9x
9x = 18; dividing both sides by 9
x = 2
given that y = -26, and substituting this into equation y = 10 - 9x,
we have, -26 = 10 - 9x
10 + 26 = 9x
9x = 36; dividing both sides by 9
x = 4
Answer:
$4.26
Step-by-step explanation:
63.90 divide by 15 = $4.26
the price of one tube is $4.26
Let us say that S is the total food sales therefore we can
create the following equation:
0.20 S = 625 + 0.10 S
Solving for S:
0.10 S = 625
S = 6250
<span>Therefore the food sales should amount to $6,250</span>
Answer:
4. A survey asking 75 people if they like the new school building
Step-by-step explanation:
A binomial experiment consist of n trials but for every trial there are only two possible outcomes.
1. A survey asking 75 people to name their favorite color
There can be more than two answers to the given question so it is not a binomial experiment.
2. A survey asking 75 people to give their age
The age can be any integer which makes the outcomes more than two so this is also not a binomial experiment.
3. A survey asking 75 people whom they voted for in the election
This is also not a binomial experiment as there can be more than two answers to the question
4. A survey asking 75 people if they like the new school building
The given question can only be answered in yes or no which means only two possible outcomes so this is a binomial experiment ..
