Answer:
7 km
Step-by-step explanation:
If I subtracted 18km by 11km my answer would be 7km
Answer:
21.1 km
Step-by-step explanation:
The northeast line and the southeast line will make a right angle so use the Pythagorean Theorem: a^2 + b^2 = c^2 and calculate c.
18² + 11² = c²
324 + 121 = c²
445 = c²
c = 21.1 km
The amounts of Cathy’s last six clothing purchases were $109, $72, $99, $15, $99, and $89. For each question, choose the mean, median, or mode and give its value.
C.) Which value would Cathy NOT tell her parents to convince them that she needs an increase in her allowance?
{I only need help on part C}
Answer:
The mean value = $80.5
Step-by-step explanation:
The value of her last six spendings are $109, $72, $99, $15, $99, and $89.
For the mean.
Mean = Total spendings/number
Mean =483/6
Mean = $80.5
For the median.
Lets arrange it in ascending order
$15 ,$72, $89, $99, $99, $109
The middle values are two.
Median = (89+99)/2
Median = 188/2
Median = $94
For the mode
$15 ,$72, $89, $99, $99, $109
Highest occuring is $99 with two frequencies.
To convince her parents that she needs an increase in allowance she would show them the bigger spendings .
So the least value on the list it's mean value which is $80.5.

145 = 2x + 15
2x = 130
x = 65 (ANS)
Answer:
65º
Step-by-step explanation:
145º = (2x + 15)º
145º = (2x + 15)º
145º - 15º = 2xº + 15º - 15º
130º = (2x)º
x = 65º

Answer:
I would say B. y = 4x + 3
Step-by-step explanation:
Because that equation is positive and going up while the other ones would be going down. i.e. positive go up while negatives go down. So your correct answer is B. y = 4x + 3
Hope this Helps. :)
Answer:
Easy.Y=4x+3
Step-by-step explanation:
Look at the point that touches the y-axis.You see it is 3.Now look at the direction the line goes,this one is going upward to the right which means it has to be a POSITIVE slope.When you can't see the point at the top,you can look downward for another point in the graph.Which in this case that other point we see is (-1,-1).Now remember,rise/run.To reach the point of the y-axis you have to go up 4 times and go right once.Which in fraction form would be 4/1 but that equals the same as just 4x.So yeah,there ya go cutie:)

How many 1/4 pound
hamburgers can be made
from 2 1/2 pounds of ground
beef?
Answer:
9 hamburgers
Step-by-step explanation:
[tex]\frac{1}{4}[/tex] × 2 = [tex]\frac{1}{2}[/tex]
[tex]\frac{1}{2}[/tex] × 5 =[tex]2\frac{1}{2}[/tex]
[tex]\frac{1}{4}[/tex] × 9 =2 [tex]\frac{2}{4}[/tex] 2
,so 9 hamburgers can be made
We need to find the number of quarter pound hamburgers that can be made from given the amount of ground beef.
10 quarter pound hamburgers can be made.
The amount of ground beef available is [tex]2\dfrac{1}{2}[/tex] pounds.
One hamburger has a mass of [tex]\dfrac{1}{4}[/tex] pound.
[tex]1\ \text{hamburger}=\dfrac{1}{4}\ \text{pound of beef}[/tex]
[tex]\\\Rightarrow 1\ \text{pound of beef}=4\ \text{hamburgers}[/tex]
[tex]2\dfrac{1}{2}\ \text{pound of beef}=(2+\dfrac{1}{2})\times4=10\ \text{hamburgers}[/tex]
So, a total of 10 quarter pound hamburgers can be made.

The average age of people attending a concert was 23 years old, with a standard deviation of 7. What percentage of people at the concert were older than 37 years old?
Answer:
2.28%
Step-by-step explanation:
We have that the mean (m) equals 23 and that the standard deviation (sd) is 7.
We can calculate the value z and in this way we can calculate the probability in this case with the calculation of the normal distribution table:
z = m - x / sd
we know that x is 37, replacing:
z = (23 - 37) / 7
z = -2
according to the normal distribution table the value of z = -2, is equivalent to 0.0228
So the probability is 2.28%

The probability of rain on Sunday is 0.7 and the probability of rain on Monday is 0.2.
What is the probability that it rains on BOTH Monday and Tuesday?
Write your answer as a decimal rounded to the nearest hundredth (2 decimal places).
Type your answer...
Answer:
0.03
Step-by-step explanation:
Given data
Probability that it will rain on Sunday= 0.7
Probability that it will rain on Monday = 0.2
Firstly we need to solve for the probability that it will rain on Tuesday
Sample space S = number of week days = 7
Probability that I will rain on Tuesday = 1/7= 0.14
Hence the probability that it rains on BOTH Monday and Tuesday= 0.2*0.14= 0.028
Rounding up the nearest hundredths = 0.03
Mr. Franco's records show that 44% of his students bring their own lunches to school. What is the percent and decimal of the students who DO NOT bring their own lunches.
Answer:
Percentage 56%
Decimal 0.56
Step-by-step explanation:
As percentages are out of 100, to work out the people who did not bring their own lunches you would simply minus the percentage of people that do which is 44 by 100, this gives you 56. this is because subtracting it from 100 we are removing the people that did from the total and so will leave us with the percentage of people that did not.
To work out the percentage who did not bring in their own lunches as a decimal you would divide the percentage of 56 by 100, this gives you 0.56. This is because percentages are out of 100%.
1) Minus 44 from 100.
[tex]100-44=56%[/tex]
2) Divide 56 by 100.
[tex]56/100=0.56[/tex]

Answer:
itsc c (0,3) ,d(3,0)
Step-by-step explanation:
If AB is divided into three equal parts then coordinates of C is (0, 3) and D coordinates are (3, 0)
What is Coordinate Geometry?A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
Divide AB into three equal parts
[tex]X_{c}-X_{a}=\frac{1}{3} (X_{B}-X_{D})[/tex]
=3
[tex]Y_{a}-Y_{c}=\frac{1}{3} (Y_{A}-Y_{B})[/tex]
=3
So C is (0, 3)
[tex]X_{B} -X_{D} =\frac{1}{3} \times 9[/tex]
=3
[tex]Y_{D} -Y_{B} =\frac{1}{3} \times 9[/tex]
=3
So D coordinates are (3, 0)
Hence, if AB is divided into three equal parts then coordinates of C is (0, 3) and D coordinates are (3, 0)

The sum of two numbers is −21. One number is 55 less than the other. Find the numbers.
Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
substitute for y:
x + x - 55 = -21
solve for x:
2x = 34
x = 17
solve for y:
17 + y = -21
y = -38
20. (x, y) → (x + 3. y - 6)
