On rolling a die, the Sample space of the given event E = {1, 2, 3, 4, 5, 6}
Sample space of numbers less than 5 = {1, 2, 3, 4}
Clearly we can see that the number of favorable outcomes = 4
Hence, P(values less than 5) = 4/6 = 2/3.
To find the complement of rolling a number less than 5, we use the formula P' = 1 - P, where P' is the complement of P.
So, let P' be the complement probability of getting numbers less than 5
Now, P'(numbers less than 5) = 1 - P(numbers less than 5)
= 1 - 2/3
= 1/3.
Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is 1/3.

A regular-size box of crackers measures 2 inches by 9 inches by 14 inches. The manufacturer also sells a snack-size box that has a volume that is 1/4 of the volume of the regular-size box. What is the volume of the snack-size box
Answers
Answer:
63
Step-by-step explanation:
2 x 9 x 14 = 252, 1/4 of 252 is 63
Answer:
63 in³
Step-by-step explanation:
Volume of regular box = width × length × height
= 9 × 14 × 2
= 252 in³
If the snack box is 1/4 of the volume of the regular-size box, to find the volume of the snack box, multiply the volume of the regular-size box by 1/4:
Volume of snack box = Volume of regular box × 1/4
= 252 × 1/4
= 252 ÷ 4
= 63 in³

Step-by-Step-Explanation:
This is a right angle, a right angle is equal to 90° since it is 1/4 of 360
(360 is all the way around)
Our equation here is;
5x° + 55° = 90°
(we do inverse operation, inverse of addition is subtraction.)
Subtract 55° from both sides, 55 - 55 cancels out (0)
90° - 55° = 35°
Now our equation is;
5x° = 35°
(to find x we need to find out what 1x equals so we divide 35° by 5°)
(35 / 5 = 7)
x = 7
To make sure we plug in it into our original equation (5x° + 55° = 90°)
5(7)° + 55° = 90°
35° + 55° = 90°
(35 + 55 = 90 so this is correct)
x = 7

Step-by-step explanation:
The area of a triangle would be 1/2 bh so the first step would be to find the area of the triangle. So, you would need to multiply 6*6 and then divide it by 1/2. Then you would need to find the area of the rectangle, for this you would need to multiply the length times the width which would be 6*11 then you just add both of the areas up. which would be 84.
Step 1: area of rectangle
A = a x b
A = 11 x 6
A = 66 in
Step 2: area of triangle
A = 1/2 x a x b
A = 1/2 x 6 x 6
A = 18 in
Step 3: total area
A = 66 + 18
A = 84 in

David has pears and apricots in a ratio of 24:20. How many pears does he have if he has 5 apricots?
On the double number line below, fill in the given values, then use multiplication or division to find the missing value.
Answers
Answer:
The answer is 6 pears.
First turn the ratio into a fraction.
The fraction would be 24/20
Next find the greatest common factor.
You do this by finding the greatest common factor which would be 4.
Four is the GCF because it is the highest number that you can divide both 24 and 20 by.
Since the question is in the order of pears then apricots you divide 24 by 4 to get the number of pears.
Your final answer is 6.

Answer:
Step-by-step explanation:

Middle triangle is: 113.4
352.35 + 113.4 = 465.75
Answer:
465.75 or 465.8 rounded to the nearest tenth
Step-by-step explanation:
You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.
Factor the expression using the GCF.
