If 7n+3=4/3 , what is the value of 7n + 5? Group of answer choice A. -5/21 B. -5/3 C. 13/3 D. 10/3
PLZ help me
Answer:D-10/3
Step-by-step explanation:
The value of 7n + 5 is 13/3
In order to determine the value of 7n + 5, the first step is to determine the value of n from the first equation given : 7n+3=4/3
7n+3=4/3
Combine similar terms
7n = 4/3 - 3
7n = 1 1/3 - 3
7n = -1 2/3
Divide both sides of the equation by 7
n = -1 2/3 ÷ 7
n = -5/3 x 1/7 = -5/21
Substitute for the value of n in this equation: 7n + 5
7(-5/21) + 5
= -5/3 + 5
= -1 2/3 + 5 = 4 1/3 = 13/3

Use z scores to compare the given values.
Based on sample data, newborn males have weights with a mean of 3259.8 g and a standard deviation of 869.7 g. Newborn females have weights with a mean of 3000.9 g and a standard deviation of 550.8 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1600 g or a female who weighs 1600 g?
Since the z score for the male is z=__and the z score for the female is z=___, the
(male or female(which one)has the weight that is more extreme.
Answer:
The answer is given below
Step-by-step explanation:
Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]
For the male:
μ = 3259.8 g, σ = 869.7 g
Hence for a male who weighs 1600 g, the z score is:
[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3259.8}{869.7}=-1.91[/tex]
For the female:
μ = 3000.9 g, σ = 550.8 g
Hence for a female who weighs 1600 g, the z score is:
[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3000.9}{550.8}=-2.54[/tex]
Since the z score for the male is z= -1.91 and the z score for the female is z= -2.54 the male has the weight that is more extreme.

If a person has the values for an object's density and volume, what value can be calculated? the object's size the object's mass o the shape the object forms in a container O the amount of space the object takes up
Answer:
B
Step-by-step explanation:
the objects mass
Density is defined as its mass per unit volume.
If a person has the values for an object's density and volume, the object's mass can be calculated.
What is density?Density is defined as its mass per unit volume.
We have,
The object's density and volume are known.
Density = Mass / Volume
So, if the density is known its mass and volume are also known.
We need to see which values can be calculated:
The object's size:
We can not calculate the object's size by knowing the volume and mass of the object.
The object's mass:
The object's mass can be calculated by knowing the density of the object.
The shape the object forms in a container:
The shape of the object can not be calculated by knowing the mass and volume of the object.
The amount of space the object takes up:
The amount of space the object takes up can not be calculated by knowing the mass and volume of the object.
Thus,
If a person has the values for an object's density and volume, the object's mass can be calculated.

3m+6-2m=-22. Solve or explain
Answer:
hope this helped you
please mark as the brainliest (ㆁωㆁ)
Answer:
-28
Step-by-step explanation:
Simplifying
3m + 6 + -2m = -22
Reorder the terms:
6 + 3m + -2m = -22
Combine like terms: 3m + -2m = 1m
6 + 1m = -22
Solving
6 + 1m = -22
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 1m = -22 + -6
Combine like terms: 6 + -6 = 0
0 + 1m = -22 + -6
1m = -22 + -6
Combine like terms: -22 + -6 = -28
1m = -28
Divide each side by '1'.
m = -28
Simplifying
m = -28

Answer:
Jack is incorrect
Step-by-step explanation:
Given:
Jack representation: [tex]-10 < -15[/tex]
Required
State with reason if Jack is correct or not
Jack representation of both elevation shows implies that -10 is less than -15
This illustration is incorrect because;
If the numbers are presented on a number line
-10 is to the right of -15
And numbers on the number line increases along the right hand side.
