When you flip a baised coin the probability of getting tail is 0.75 How many times would you expect to get tails uf you flip the coin 320 times?
Answer: 60
How?: Well, we know that we have a 0.75 chance for tails. And on a coin, there is heads and tails. So, we multiply 0.75 (tails) by 320 and then divide that by 4. We do this because there is a 0.75 and 1 = 1.00. 1.00 - 0.75 = 0.25. 0.25 = 60

Answer:
Step-by-step explanation:
The discriminant of ax^2+bx+c=0 is b^2-4ac, in this case
4^2-4(2)10
16-80
-64
Since -64<0 there are two imaginary (or ‘complex’) solutions.
Note: if d=0, there is one real solution. if d>0, there are two real solutions.

Micheal has 4 red shirts, 3 green shirts, and 5 blue shirts in his closet. If he randomly selects a shirt, what is the probability he chooses green or red.
a) 1/3
b) 1/4
c) 5/12
d) 7/12
Answer:
D. 7/12
Step-by-step explanation:
First, find the total number of shirts in his closet:
4 + 3 + 5
= 12
Now, find how many are green or red:
4 + 3
= 7
Since 7 out of 12 shirts are green or red, the probability that Micheal chooses green or red is D. 7/12
Dorothy is thinking of two numbers. The sum of the two numbers is 40 and the difference is 6. Write a system of equations and use the elimination method to find the two numbers.
Answer:
x = 23
y = 17
Step-by-step explanation:
x = 1st number
y = 2nd number
System of Equations:
x + y = 40
x - y = 6; this can be used as x = 6+y
6+y + y = 40
6 + 2y = 40
2y = 34
y = 17
x + 17 = 40
x = 23

Kara is painting flowerpots. She uses 1/3 cup of paint for each flowerpot.
How many cups of paint does Kara use for 2 flowerpots? Show or explain how you got your answer.
Answer:
2/3
Step-by-step explanation:
1/3 x 2/1 =2/3
if she uses 1/3 for one we just have to double it to get the answer
Answer:
2/3
Step-by-step explanation:
if she uses 1/3 for one she uses 2/3 for 2 because 1/3 times 2 is 2/3
step 1 Address formula, input parameters & values
1/3 and 2/1
1/3 times 2= ?
step 2 Multiply both numerators
= 1 x 2
= 2
step 3 Multiply both denominators
= 3 x 1
= 3
step 4 Use above values of step 2 & 3, and rewrite as below
= 2/3
thus, 2/3 is equivalent fraction for 1/3 times of 2.
Use the distributive property to rewrite the expression 5(4x. + 7)
Answer: The answer is 20x + 35
Step-by-step explanation: 5(4x+7) You multiply 5 in both numbers and you get 20x+35
Answer: 20x+35
Step-by-step explanation:
Multiply both terms in the parenthesis by 5. 4x times 5 is equal to 20x, and 7 times 5 is equal to 35.

Answer:
B. 95º
Step-by-step explanation:
Supplementary angles are ones that add up to 180º.
So if angle 1 is 85º, then the equation would be:
(x-the measure of angle 2)
X + 85 = 180
Solve for x:
X + (85-85) = 180-85
X = 95.
Hope this helps! Have a great day!
Answer:
it is B) 95
Step-by-step explanation:
supplementary mean equals to 180. in a triangle problem all the angles should add up to 180. so you take 180 and subtract the number you already have which is 85 and you get 95
Q4 - Exam prep: Missing values
Audrey measures all 7 pencils in her pencil case and writes the first 6 lengths down.
12.4 cm, 12.6 cm, 13 cm, 13.4 cm, 13.5 cm, 13.3 cm
Audrey calculates the mean length of all 7 pencils to be 13.1 cm.
Find the length of the missing pencil.
cm
[2]
Answer:
the missing pencil length is 13.5 cm
Step-by-step explanation:
The computation of the length of the missing pencil is shown below:
Let us assume the missing pencil be x
Now
(12.4 cm + 12.6 cm + 13 cm + 13.4 cm + 13.5 cm + 13.3 cm + x) ÷ 7 = 13.1 cm
(78.2 cm + x) ÷ 7 = 13.1 cm
78.2 cm + x = 91.7 m
So, x would be
= 91.7 cm - 78.2 cm
= 13.5 cm
hence, the missing pencil length is 13.5 cm

12. ALGEBRA Sherri Cole found that the 12-ounce can of frozen orange juice
sells for $0.16 less than the 16-ounce can, which is $0.68 less than the
24-ounce can. If the unit price of the 24-ounce can is $0.005 less than the
unit price of the 12-ounce can, which of the three is the best buy based
on the lowest unit price?
Answer:
96 = x
Step-by-step explanation:
I'm going to use cents instead of dollars because I find decimals and fractions to be cumbersome. I assume you meant $.005 instead of 4.005.
Let x denote the price (in cents) of the 12-ounce can. Then the price of the 16-ounce can is (x + 16) cents, and the price of the 24-ounce can is ((x + 16) + 68), or (x + 84) cents.
The unit price (cents per ounce) of the 12-oz can is x/12
The unit price of the 16-oz can is (x + 16)/16
The unit price of the 24-oz can is (x + 84)/24
You are told that, in terms of x,
(x + 84)/24 = x/12 - 0.5
Multiply both sides by 24:
x + 84 = 2x - 12
Solve for x:
96 = x
So the unit prices (in cents per ounce) are:
12 oz: 96/12 = 8 cents/oz
16 oz: 112/16 = 7 cents/oz
24 oz: 180/24 = 7.5 cents/oz
So the 16 ounce can is the best buy based on lowest unit price.
In this exercise we have to use the knowledge of finance to calculate the best price to be offered, in this way:
[tex]12 oz: 96/12 = 8 cents/oz\\16 oz: 112/16 = 7 cents/oz\\24 oz: 180/24 = 7.5 cents/oz[/tex]
Some values should be simplified as they were informed in the statement:
The unit price (cents per ounce) of the 12-oz can is x/12The unit price of the 16-oz can is (x + 16)/16The unit price of the 24-oz can is (x + 84)/24So putting together an equation with these values and terms informed we find that:
[tex](X + 84)/24 = X/12 - 0.5\\X + 84 = 2X - 12\\X=96[/tex]
So with the value of X found it is only necessary to use the previous equations and replace this value.
