11x2
Answer:
11 x 2
Step-by-step explanation:
By BODMAS rule,
B - Brackets
O - Orders
D - Division
M - Multiplication
A - Addition
S - Substraction
Consider DMAS alone.
Here, there is no division.
So,
Multiplication ( x ) should be the first step.

The pressure on a diver in the water varies directly as the depth. If the pressure is 3.6 Ib/in^2 when the depth is 8ft, what is the pressure when the depth is 30ft.
I give Brainliest! Please show your work
Answer:
13.5 lb/in^2
Step-by-step explanation:
8ft = 3.6 lb
30ft= ?
8ft÷30ft = 3.75
this means 8ft goes into 30ft 3.75 times
3.6lb× 3.75=13.5lb/in^2
you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft
What is the equation of the vertical line through (-8,5)(−8,5)left parenthesis, minus, 8, comma, 5, right parenthesis?
What is the equation of a line that is parallel to the line y = 5x – 1 and passes through the point (4, –3)? A. y = 5x + 19 B. y = –5x + 17 C. y = 5x – 23 D. y = –15x – 115
Answer:
y = 5x - 23
Step-by-step explanation:
Slope: 5
Point (4, - 3)
y-intercept: -3 - (5)(4)
= -3 -20 = -23
y = 5x - 23
x^2 - 6x + 1 = 0 by completing the square
Answer:
See below.
Step-by-step explanation:
x^2 - 6x + 1 = 0
x^2 - 6x = -1
We halve the coefficient of x (which is -6/2 = -3) and square it, then add this to both sides:-
x^2 - 6x + (-3)^2 = -1 + (-3)^2
x^2 - 6x + 9 = -1 + 9
(x - 3)^2 = 8
x - 3 = ±√8
x = 3 ± √8
= 0.17, 5.83 to 2 decimal places.
Answer:
[tex]x = - 2 \sqrt{2} + 3 \\ or \\ x = 2 \sqrt{2 } + 3[/tex]

The living room in the house has an area of 78 square feet and a width of 12 feet. What is the length of the room?
Answer:
6.5 feet
Step-by-step explanation:
the formula for the area is A=l*w l=length w=width
A=l*w
78=l*12
Divide both sides by 12
78/12=6.5
Decide if the following statement is true or false. A simple random sample of twelve 2+ bedroom houses in Rockingham County has a mean monthly lease of $695 with a standard deviation of $135. The true rental cost will be from $560 to $830
Answer:
Step-by-step explanation:
783
The given statement is "False" because the statement's range is based on the mean and standard deviation of a simple random sample of houses, not the whole population of Rockingham County's houses..
What is a simple random sample?A simple random sample is a subset of a population chosen in a way that gives each member of the population an equal chance of being selected. The mean and standard deviation of a simple random sample provides information about the population from which the sample was drawn, but they do not provide a range in which the true value of a population parameter is guaranteed to fall.
In this case, the statement provides a range for the true rental cost of 2+ bedroom houses in Rockingham County, but there is no guarantee that the true rental cost will fall within this range. The range provided in the statement is based on the mean and standard deviation of a simple random sample of houses, not the entire population of houses in Rockingham County.
Hence, the given statement is False.

how do you find the coefficient on a scatterplot?
Answer:
The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.

Find the equation of the line passing through the points (-3,8) and (3,-4). Write the
equation in slope-intercept form.
Answer:
y = -2x + 2
Step-by-step explanation:
(-4-8)/(3-(-3)) = -12/6 = -2
-4 = -2(3) + b
-4 = -6 + b
b = 2
The population of insects in an experiment has
been increasing by 9% each week. If there were 16
insects at the beginning of the experiment, predict
how many insects there will be after 8 weeks.
First, complete the equation:

Answer:
8
Note: I got it right on the same test you took as me.
The value of time period for the equation is 8.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The population of insects is increasing by 9% each week = 0.09
At the beginning of the experiment, number of insects = 16
Number of insects increased per week
⇒ [tex]16+16(0.09)[/tex]
Let the time period be x.
Number of insects increased after 8 weeks can be found by the equation,
[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]
⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]
Hence we can conclude that the value of time period for the equation is 8.
