Answer:
blue point value is -10
Step-by-step explanation:
First lets find the difference between each point on the line,
The gap between 10 and 2 has 2 points
So 10 - 2 = 8 is the difference in value between point A(10) and point C(2), but we need to find difference between each point,
So 8/2 = 4 is the difference between each point from top to bottom.
There is 3 points after 2 to reach blue,
So 4 x 3 = 12, is the difference in value between point C(2) and point blue,
So, subtracting 12 from 2 will get us the value of blue, 2 - 12 = -10
Therefore the value of blue point is -10
Happy to help :)

Based on the table, do the data support the use of a normal model to approximate population characteristics?
A Yes, because the sum of the relative frequencies is 1.00.
B
Yes, because the distribution of relative frequencies is very close to the empirical rule for normal models.
с
No, because the values are negative and normal models are used for positive values.
D
No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
E
No, because the sample size and the population parameters are not known.

Answer:
B
Step-by-step explanation:

The correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
To determine if the data supports the use of a normal model to approximate population characteristics, we need to examine the relative frequencies and see if they exhibit a bell-shaped or normal distribution.
Looking at the table, we see that the relative frequencies are not symmetrical and do not follow the empirical rule for normal models.
The largest relative frequency is in the interval from -0.28 to -0.25, and the frequencies decrease as we move away from this interval. Additionally, there are negative values in the data, which is not a characteristic of normal models.
Therefore, the correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.

Step-by-step explanation:
last week:
d = 18
d = 18h = 6
this week:
d = 2.5h
i. if she walked for 6 hours this week, h = 6
d = 2.5h
d = 2.5 × 6
d = 15
* this means she walked at slower pace this week as she can only cover 15 miles in 6 hours whereas she can cover 18 miles in 6 hours last week
ii. if she walked for 18 miles this week, d = 18
d = 2.5h
18 = 2.5h
h = 18/ 2.5
h = 7.2
* this means she walked at a slower pace this week as she needs 7.2 hours to cover 18 miles whereas she only need 6 hours last week

Step-by-step explanation:
Range: output values of a function (y-values)
Given function:
[tex]f(x)=\dfrac{3}{4}|x|-3[/tex]
This is an absolute value function so |x| ≥ 0
Therefore, as |x| ≥ 0:

The formula 2 equals 18+ B plus he gives the perimeter P of a triangle decide links a B in C a triangular feel has issac measure 45 yards 29 yard and 34 yards with the perimeter of the field the perimeter of the field is?
Answers
Answer:
P = 646 yards
Step-by-step explanation:
The sides of a triangular field measure 45 yards 29 yard and 34 yards.
The formula that is used to find the perimeter is given by :
P = 2A+18B+C
Put A = 45, B = 29 and C = 34 to find the perimeter of the field.
P = 2(45)+18(29)+34
= 90 + 522 + 34
= 646 yards
Hence, the perimeter of the field is 646 yards.

Abdulla took a takie from his home to the air port. The taxi driver chared an initial fee of 12AED pluse 2.50AED per km. How much change should the taxi driver give mr abdulla bach if he gave him 100AED at the end of his trip
Answer:
88 - 2.50x
Step-by-step explanation:
Given :
Initial charge = 12
Charge per kilometer = 2.50
Amount given to driver = 100
Let distance from home to airport = x
Total charge = (initial charge + (distance * charge per km)
Total charge = 12 + 2.50x
Change = (Amount given to driver - total charge)
Change = (100 - (12 + 2.50x))
100 - 12 - 2.50x
88 - 2.50x

In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is 1/3 the length of the corresponding side of triangle ABC. What is the value of sinF?
Answers
Answer:
Sin F = 0.6
Step-by-step explanation:
From triangle ABC, applying Pythagoras theorem to determine the length AB;
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/AC/^{2}[/tex] = [tex]/BC/^{2}[/tex] + [tex]/AB/^{2}[/tex]
[tex]/20/^{2}[/tex] = [tex]/16/^{2}[/tex] + [tex]/AB/^{2}[/tex]
400 = 256 + [tex]/AB/^{2}[/tex]
[tex]/AB/^{2}[/tex] = 400 - 256
= 144
AB = [tex]\sqrt{144}[/tex]
= 12
AB = 12, AC = 20, BC = 16
Therefore since ΔABC ≅ ΔDEF, and each side of triangle DEF is [tex]\frac{1}{3}[/tex] the length of the corresponding side of triangle ABC.
Then,
DE = [tex]\frac{1}{3}[/tex]AB = [tex]\frac{1}{3}[/tex] x 12
= 4
EF = [tex]\frac{1}{3}[/tex]BC = [tex]\frac{1}{3}[/tex] x 16
= [tex]\frac{16}{3}[/tex]
DF = [tex]\frac{1}{3}[/tex]AC = [tex]\frac{1}{3}[/tex] x 20
= [tex]\frac{20}{3}[/tex]
Then, applying trigonometric function to ΔDEF, we have;
Sin F = [tex]\frac{opposite}{hypotenuse}[/tex]
= [tex]\frac{DE}{DF}[/tex]
= 4 ÷ [tex]\frac{20}{3}[/tex]
= 4 x [tex]\frac{3}{20}[/tex]
= [tex]\frac{3}{5}[/tex]
Sin F = 0.6

which is the correct graph for the equation?
Answers
Answer:
From the given graph, we can easily determine that graph A contains the y-intercept b = 3.
Thus, option A is the correct option.
The graph of the equation is also attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the function
2x+5y=15
converting the equation into the slope-intercept form
5y = -2x + 15
divide both sides by 5
y = -2/5x + 3
Thus,
The slope of the line is: m = -2/5
The y-intercept of the line: b = 3
In other words, the ordered pair (0, 3) represents the y-intercept.
From the given graph, we can easily determine that graph A contains the y-intercept b = 3.
Thus, option A is the correct option.
The graph of the equation is also attached below.
