What is the mean of the values in the dot plot?
Enter your answer in the box.
Answer:
The mean is 46.
Step-by-step explanation:
To find the mean of these points add the values together. So that's one 40, two 41's, one 45, two 48's, three 49's and one 50.
40 + (2 * 41) + 45 + (2 * 48) + (3 * 49) + 50
Multiply what's in the parentheses.
40 + 82 + 45 + 96 + 147 + 50
Add, going from left to right
122 + 45 + 96 + 147 + 50
167 + 96 + 147 + 50
263 + 147 + 50
410 + 50
460
Now, divide that by how many dots there were (10).
460/10
The mean of the values in this dot plot is 46.

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)
Answer: 4.2*w + 7*x + 5.4
Step-by-step explanation:
Here we need to remember how the product of different signs works, here is the rule:
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Now we want to distribute the negative sign in the equation:
"-(-4.2w-7x-5.4)"
We can write this as:
-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)
Now we can distribute the "-1"
Then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)
We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:
(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4

3 cups of tea and 4 cups of coffee costs £3.45 in total.
4 cups of tea and 1 cup of coffee costs £2.65 in total.
How much would it costs to buy one cup of each in total?
Answer:
A) 3T + 4C = 3.45
B) 4T + 1C = 2.65 We'll multiply this by -4
B) -16T -4C = -10.60 then we'll add A)
A) 3T + 4C = 3.45
-13T = -7.15
Tea is .55
and coffee is
A) 3 * .55 + 4C = 3.45
4C = 3.45 -(3 * .55)
4C = 1.80
coffee is .45

Simplify the expression -(6 - 4p)
Hey there!
The answer to your question is [tex]-6+4p[/tex]
Given:
[tex]-(6-4p)[/tex]
First, we distribute the negative sign to both terms ([tex]6[/tex] [tex]and[/tex] [tex]-4p[/tex]) This would make the [tex]6[/tex] negative and the [tex]-4p[/tex] positive, so we have:
[tex]-6[/tex] [tex]and[/tex] [tex]4p[/tex]
Add them together and we get:
[tex]-6+4p[/tex]

Someone help me I don’t know how to do this
Answer:
17 and 59
Step-by-step explanation:
90-75=17 first one
180-121=59 second one plz give me brainnessttttt pllzzzz
Hey there!
So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.
The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.
Remember:
A complementary angle is made of up TWO angles that add up to 90 degrees.
A supplementary angle is made up of TWO angles that add up to 180 degrees.
I hope this helped!!!
What is a slope in mathematical terms
Answer:
"The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x)."
Answer:
It is how steep a linear graph/function is.
Step-by-step explanation:
It is the m in the formula y=mx+b. The bigger the member the steeper.
Parallel/perpendicular definition
Answer:
Parallel: extending in the same direction, everywhere equidistant.
Perpendicular: ar an angle of 90 to a givin line, plane or surface.
Answer:
Two or more straight lines having equal distance between them through out is parallel lines
Perpendicular lines are two lines at Right angles

x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

f(x)=6^x for x=2 help please
9514 1404 393
Answer:
f(2) = 36
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 6^2
An exponent of 2 means 6 is a factor two times.
f(2) = 6×6
f(2) = 36
Answer:
36
Step-by-step explanation:
To evaluate f(x) = 6^x at x = 2, substitute 2 for x:
f(2) = 6^2 = 36

–19w + 11 = –17w − 19
w=
Please help, will mark brainliest to correct answer!
Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15
