Answer:
FalseFalseFalseFalseTrueStep-by-step explanation:
A) False ; R^2 is not a two dimensional subspace of R^3 because Vector R^2 will have 2 entries while vector R^3 has 3 entries
B) False : The number of variable in the equation is not equal to the Dimension because dim of Null A represents the number of free variables
C) False : This is because you can span R^3 with an infinite set of vectors but that doesn't make it infinite dimensional subspace
D) False : This is only possible when S has exactly n elements/vectors
E) True : Since R^3 is a three dimensional subspace it is spanned with 3 vectors whom are linearly independent
How many sides does a polygon have if the sum of its interior angle measures is
7380°?
43
if so, use the formula for sum of interior angles in a polygon to solve. 7380 = (n - 2)(180), where n is the number of sides. The number of sides of the polygon is 43.
There are 43 sides in a polygon, if the sum of its interior angle measures is 7380°.
What is Polygon?A Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane.
We have to find the number of sides in a polygon.
The sum of its interior angle measures is 7380°
The sum of the interior angles of a polygon can be calculated using the formula S = (n - 2) x 180°
where n is the number of sides of the polygon
7380 = (n-2)×180
We have to solve for n
Divide both sides by 180
7380/180=n-2
41=n-2
Add 2 on both sides
43 = n
Hence, there are 43 sides in a polygon, if the sum of its interior angle measures is 7380°.

Garrick and Zan are measuring the heights of seedling plants for science class.
Use the drop-down menus to complete the statements about the measured heights and the actual heights of the plants.
CLEAR CHECK
Because Garrick's plant is... than Zan's plant, each millimeter of error results in a ....percent error.
Garrick's measurement was ... millimeters off and Zan's was... millimeters off, so Garrick's measurement was ... % off and Zan's was
Garrick's measurement was 2 mm off. (10 - 8 = 2)
Zan's measurement was 12 mm off. (100 - 88 = 12)
Garrick's percent error was 20% (2 / 10 x 100)
Zan's percent error was 12% (12 / 100 x 100)

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
Given:
1,050 calories should be consumed daily for a 105-pound person.
Now, to get the weight of an individual who consumes 1,370 calories per day.
If 1,050 calories should be consumed per day for = 105-pound person.
So, 1 calorie should be consumed per day for =105/1050
=1/10
Then, 1,370 calories consumed per day for weight of =1370/10
= 137 pounds
Therefore, the weight of an individual who consumes 1,370 calories per day is 137 pound.

Subtract 8 1/6- 4 5/6 . Simplify the answer and write as a mixed number
Answer: 3 1/3
Step-by-step explanation: You change 8 1/6 to improper fraction which is 49/6 and change 4 5/6 to improper fraction which is 29/6. Next you take 49/6 and subtract 29/6 which is 20/6.After that you simplify 20/6 by divide both sides by 2 which gives you 10/3.Lastly change 10/3 to a mixed number which is 3 1/3.

Mandy runs 4 km in 18 minutes. She plans to run in a 16 km race. Based on her current speed. how long will it take her to complete the race
Answer:
72 minutes
Step-by-step explanation:
You need to set up 2 fractions and set them equal to one another to be able to solve this.
Equation: 4km/18min = 16km/x min
You need to find x. In order to do this you can use that butterfly method/cross multiplication. You do 4 times set equal to 18*16.
Next, you get 18*16=288 and you must divide the other side (4x) to get your final answer. So, 288/4= 72 minutes.

A stationery store wants to estimate the mean retail value of greeting cards that it has in its inventory. A random sample of 15 greeting cards indicates an average value of $3.00 and a s of $0.40. The critical value for a 99% confidence interval is
Answer:
The critical value for a 99% confidence interval is T = 2.9768
Step-by-step explanation:
We have the standard deviation of the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 15 - 1 = 14
Critical value
Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.9768
The critical value for a 99% confidence interval is T = 2.9768

Please help thank you
Answer:

Step-by-step explanation:
The equation 8 - 9 + 8 / 4 is given.
When solving equations with multiple signs in them, we need to follow PEMDAS.
Which is an acronym for a series of equations you need to follow in order.
Parenthesis
Exponent
Multiply
Divide
Addition
Subtraction.
So look at the equation, 8 / 4 would be first since it is dividing.
8 / 4
2
8 - 9 + 2
Now when it comes down to the last two of PEMDAS (Addition and Subtraction), we can just solve left to right.
Therefore,
8 - 9

-1 + 2
