find the value of x. 2x 20
Answer:
X = 10
Step-by-step explanation:
Since 2x = 20
we can divide 2 from both sides giving us x = 20/2
Therefore , x = 10 because 20 divided by 2 is 10
Answer:
X= 10
Step-by-step explanation:
2X=20
Then Divide both sides by 2 in order to find the value of X
2X/2=20/2
X= 10

Researchers at a drug company are testing the duration of a new pain reliever. The drug is normally distributed with a mean duration of 240 minutes (4 hours) and a standard deviation of 40 minutes. The drug is administered to a random sample of 10 people. (Round means, standard deviations, and z-scores to the nearest hundredth, if necessary.)
The population mean of the sampling by the researcher is 240, the standard deviation is 40 and the z score is -2.
What is a mean?It should be noted that the mean is the average of the numbers that are given in a population. The z score is -2 as it measures the relationship between the means.
The probability that the drug will wear off between 200 and 220 minutes will be:
= P(Z < -1.58) - P(Z < -3.16)
= 0.0571 - 0.0008
= 0.0563.

The area of the regular hexagon is 10.4 in.2. a regular hexagon has side lengths of 2 inches and an area of 10.4 inches squared. an apothem is shown. what is the measure of the apothem, rounded to the nearest tenth of an inch? 1.3 in. 1.7 in. 2.0 in. 3.4 in.
Answer:
(b) 1.7 in
Step-by-step explanation:
The area of a regular polygon in terms of perimeter and apothem is given by the formula ...
A = 1/2Pa
For a hexagon, the perimeter is 6 times the side length, so this becomes ...
A = 1/2(6s)a = 3sa . . . . . for side length 's' and apothem 'a'
__
Solving for the apothem, we find ...
a = A/(3s)
For the given values of area and side length the apothem is ...
a = 10.4/(3·2) = 1.733... ≈ 1.7 . . . inches
The apothem, rounded to tenths, is 1.7 inches.
Answer:
1.7 in.

Please help!!! Eitan randomly selected volcanoes to travel to and study. After traveling, he had seen 13 cinder cone volcanoes,
18 shield volcanoes, and 6 stratovolcanoes.
Answer:
cinder cone: estimated probability = 0.35
shield: estimated probability = 0.49
stratovolcano: estimated probability = 0.16
Step-by-step explanation:
Given that he had seen 13 cinder cone volcanoes, 18 shield volcanoes, and 6 stratovolcanoes.
So the total number of volcanoes are 13 + 18 + 6 = 37
So the estimated probability of Cinder cone is \frac{13}{37}\approx 0.35

13
≈0.35
The estimated probability of Shield is \frac{18}{37}\approx 0.49

Answer:

Step-by-step explanation:
that's it for you dear
The relationship between food purchased and food eaten by dogs can be written as, 162 biscuits ≥ 80 biscuits
What is multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.
First, let's calculate the total number of dog biscuits that Jim has bought:
= 6 bags × 27 biscuits per bag
= 162 biscuits
Next, let's calculate how many biscuits the dog will eat in 4 weeks:
= 4 weeks × 5 biscuits per day
= 20 biscuits per week
20 biscuits per week × 4 weeks = 80 biscuits
So, Jim has bought 162 biscuits and his dog will eat 80 biscuits in 4 weeks. This means that Jim has brought enough dog biscuits for his dog for 4 weeks.
162 biscuits ≥ 80 biscuits

Adding and subtracting expressions:
a) M + (5x² -2xy) = 6x² +9xy - y²
M = 6x² + 9xy - y² - (5x² - 2xy)
Remove the parenthesis by mulplying each term of 5x² - 2xy by (-1) as (-1) is outside the parenthesis
= 6x² + 9xy - y² - 5x² + 2xy
Combine ( add or subtract) like terms.
= 6x² - 5x² + 9xy + 2xy - y²
= x² + 11xy - y²
Hint: Like terms have same variable with same power.
Here, like terms are (i) 6x² and (-5x²) (ii) 9xy and 2xy
b) (3xy - 4y²) - N = x² - 7xy + 8y²
3xy - 4y² = (x² - 7xy + 8y²) + N
3xy - 4y² - (x² - 7xy + 8y²) = N
3xy - 4y² - x² + 7xy - 8y² = N
3xy + 7xy -4y² - 8y² -x² = N
10xy -12y² - x² = N
Answer: N = 10xy - 12y² -x²

ruben is buying bricks for a project. he knows that 5 bricks weigh 26 1/4. he wants to know the weight of 24 bricks
Answer:
the weight of 24 bricks is :
[tex]124\frac{4}{5}[/tex]
Step-by-step explanation:
[tex]26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}[/tex]
It is clear that there is a proportional relationship between the number of bricks and their weights then :
[tex]\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right) }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}[/tex]
[tex]\Longrightarrow x=\frac{26\times 24}{5} =\frac{624}{5} =124\frac{4}{5}[/tex]

The equation v=68t represents the number of views v for a video after t hours. Identify the independent and dependent variables.
Answer(s):
Dependent variable: vIndependent variable: tWhat is the dependent variable of an equation?
The dependent variable of an equation is the variable that is completely isolated on one side.
What is the independent variable of an equation?
The independent variable is the variable that is not isolated. The independent variable can either have a cooeficient or has some operation (+ - × ÷) included on that side of the equation.
Determining the independent and dependent variable
In this equation, we can see that "v" is completely isolated on one side and "t" has a cooeficient of 68. Thus, the dependent variable is "v" and the independent variable is "t".
