getting a sum of either 7, 10, or 11 on a roll of two dice
Which expressions are equivalent to 16? Select each correct expression
1 to the 16th power
2 to the 4th power
4 to the 2nd power
8 to the 2nd power
16 to the power of 0
16 to the power of 1
Answer: Choose 2 to the 4th power, 4 to the 2nd power, and 16 to the power of 1
Step-by-step explanation:
When working with exponents, whatever number is the corner of another number, multiply it by itself. For instance, if you have 2 to the 4th power, multiply 2x2x2x2 which is 16. Also there is 4 to the 2nd power which is 4x4 which is also 16. Lastly you have 16 to the power of 1 and anything multiplied by 1 stays the same.
Correct choices are 2 to the 4th power, 4 to the 2nd power, and 16 to the power of 1.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The maximum weight ,w, an elevator can lift is 2,200 pounds. Which inequality represents the situation??
Answer:
W is less than or equal to 2200
Step-by-step explanation:
(I don't know how to do the less than or equal to symbol on the computer)
The inequality equation is w ≤ 2200 , where w is the maximum amount of weight in an elevator
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Let the maximum weight in an elevator be w
Now , the maximum weight an elevator can lift is given by = 2,200 pounds
So , the inequality relation is given by
w ≤ 2,200 pounds be equation (1)
Therefore , the value of A is w ≤ 2,200
Hence , the inequality relation is w ≤ 2,200

For the first one, any two shades of paint will be different if they're different numbers, and the same shade if they're the same numbers. Knowing this, we can see:
A , D, and E are all the same number (1/3) so they're all the same shade.
The remaining shades (B and C) are both 1/2 so they're the same shade.
Therefore there are two different shades of paint.
For the second one, we know that the more red the shade is, the larger the fraction will be. So we just need to look for the shades with the largest fraction. These are shades B and C, because they are both 1/2 (aka 50% red), whereas all the others are 1/3 (aka 33.3% red).

Assume the readings on thermometers are normally distributed with a mean of 0C and a standard deviation of 1.00C. Find the probability that a randomly selected thermometer reads between and and draw a sketch of the region.
Complete Question
Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.0°C. Find the probability that a randomly selected thermometer reads between 0.50°C and 1.50°C and draw a sketch of the region.
Answer:
0.24173
Step-by-step explanation:
We would solve this question using Z score formula.
z = (x-μ)/σ
where:
x is the raw score
μ is the population mean = 0°C
σ is the population standard deviation = 1°C
For x = 0.5°C
z = (0.5 - 0)/1
z = 0.5
Probability value from Z-Table:
P(x = 0.5) = 0.69146
For x = 1.5°C
z = (1.5 - 0)/1
z = 1.5
Probability value from Z-Table:
P(x = 1.5) = 0.93319
The probability of that a randomly selected thermometer reads between 0.50°C and 1.50°C is calculated as:
P(0.5 < Z < 1.5) = P(x = 1.5) - P(x = 0.5)
= 0.93319 - 0.69146
= 0.24173
