There are 4 consecutive integers that have a sum of 54. What is the greatest of the 4 integers?
Answer:
x + x-1 + x-2 + x-3 =54.
x-1
Answer:
15
Step-by-step explanation:
Let the consecutive numbers be x, x + 1, x + 2, x + 3
==========
x + x + 1 + x + 2 + x + 3 = 544(x) + 6 = 544(x) = 54 - 64(x) = 48x = 12Greatest of the 4 integers:
x + 312 + 315i do not know this answer
We know that 2+2 is 4.
34 - 4 is 30.
Therefore, the legnth, a, is half of thirty.
30/2 = 15
a = 15
[tex]\bf a= 15\;\; millimetetrs[/tex]
Step-by-step explanation:
perimeter: 34 millimetetrs
perimeter= [tex]\tt a+2+a+2=34[/tex]
[tex]\tt 2a+4=34[/tex]
[tex]\tt 2a+4-4=34-4[/tex] (Subtract 4 from both sides)
[tex]\tt 2a=30[/tex] (Simplify)
[tex]\tt \cfrac{2a}{2}=\cfrac{30}{2}[/tex] (Divide both sides by 2)
[tex]\tt a=15[/tex]
Therefore, a= 15 millimetetrs.

Which scatterplot shows a linear association?
Answer:
B
Step-by-step explanation:
A linear association means the function is a relation that can be shown with a line.
The first scatterplot is in the form of a parabola, and parabolas are the quadratic function form, meaning it cannot be linear.
Next, the second scatterplot goes diagonally, in a straight line. If we were to connect the dots using a line, then it would be a linear association, meaning that B is the correct answer.
Match the correct angle measurement with its letter from the diagram.
42
48
90 are the options
Answer:
<C=48 because 90-42=42 as in the other side of the triangle.
<B=42 because vertical angles are always congruent.
<B+<D=90 because <D is 48 because it is vertical to <C

Please I really need it :(
Answer:

Step-by-step explanation:
This equation would be used to find a because we don't know how many assists are for each match. And multiplying the a by the 6 games would be equivalent to 42 assists for the entire match.

Rectangle abcd is similar to rectangle pqrs given that ab =14cm bc =8cm and pq=12cm calculate the length of qr
Answer: 6.8571 (Round as needed)
Hope this is correct
Step-by-step explanation:
This is a simple ratio problem
Using the similarity statement we can say 14:12, (ab:pq)
That is our ratio.
So we do 14/12 = 8/x, we solve this using algebra to get our answer.
Hope this is correct.
Why do you replace y with 0 when finding the x-intercept of a graph?
Here’s what you need to know about intercepts. The x intercept of a graph has y coordinate zero. The y intercept of a graph has x coordinate zero.
AN EXAMPLE OF THIS IS:
So if you have a function y = 2x + 8 you would set x = 0 to find the y intercept. So we would get y = 8. To find the x intercept we would set y = 0 and get 0 = 2x + 8
or -8 = 2x or x = -4
Now if you have a more difficult like function y = 3x^2 + 10x - 4 we proceed the same way. To find the y intercept we would set x = 0 and get y = -4 so the y intercept is (0,-4)
To find the x intercept we would set y = 0 and get 3x^2 + 10x - 4 = 0. If you know the quadratic formula you could solve this by:
x = [-b +- SR(b^2 - 4*a*c] / 2a
so in our case x = [-10 +- SR(100 - 4*3*(-4))] / (2*3)
x = [-10 +- SR(100 + 48)] / 6
x = [-10 +- SR (148)] / 6
x = [-10 +- 12.2] / 6 approximately
x = [-10 - 12.2] / 6 or [-10 + 12.2 / 6]
x = -22.2/6 or 2.2/6

ABCD.
The parallel to (BD) passing through M.cuts the
line (AD) at P
Calculate AP and MP in terms of x
4° Prove that the perimeter of the polygon
MNCDP is independent from x
Answer:
Question 1
Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, or a right triangle)
Given:
a = BCb = AB = 8cmc = AC = 10 cm⇒ BC² + 8² = 10²
⇒ BC² = 36
⇒ BC = 6 cm
Question 2
Given:
AB = 8 cmAM = x⇒ MB = AB - AM = 8 - x
As ΔABC ~ ΔMBN
⇒ AB : AC = MB : MN
⇒ 8 : 10 = (8 - x) : MN
[tex]\sf \implies \dfrac{8}{10}=\dfrac{(8-x)}{MN}[/tex]
[tex]\sf \implies \dfrac45=\dfrac{(8-x)}{MN}[/tex]
[tex]\sf \implies MN=\dfrac54(8-x)[/tex]
Question 3
D = (6, 8)
As ΔBAD ~ ΔMAP
⇒ AB : AD : BD = AM : AP : MP
⇒ 8 : 6 : 10 = x : AP : MP
[tex]\sf \implies \dfrac{8}{6}=\dfrac{x}{AP}[/tex]
[tex]\sf \implies AP=\dfrac34x[/tex]
[tex]\sf \implies \dfrac{8}{10}=\dfrac{x}{MP}[/tex]
[tex]\sf \implies MP=\dfrac54x[/tex]
Question 4
Perimeter of MNCDP = MN + NC + CD + PD + MP
As ΔABC ~ ΔMBN
⇒ AB : BC : AC = MB : BN : MN
⇒ 8 : 6 = (8 - x) : BN
[tex]\sf \implies \dfrac86=\dfrac{(8-x)}{BN}[/tex]
[tex]\sf \implies BN=\dfrac34(8-x)[/tex]
NC = BC - BN
[tex]\sf \implies NC=6-\dfrac34(8-x)[/tex]
PD = 6 - AP
[tex]\sf \implies PD=6-\dfrac34x[/tex]
Perimeter of MNCDP = MN + NC + CD + PD + MP
[tex]\sf \implies perimeter=\dfrac54(8-x)+6-\dfrac34(8-x)+8+6-\dfrac34x+\dfrac54x[/tex]
[tex]\sf \implies perimeter=10-\dfrac54x+6-6+\dfrac34x+8+6-\dfrac34x+\dfrac54x[/tex]
[tex]\sf \implies perimeter=10+8+6=24[/tex]

Mathew finds the deepest part of the pond to be 185 meters
Which measurement describes the depth of the pond?
[tex]\sqrt{196} = 14[/tex], and since [tex]\sqrt{185[/tex] is less than [tex]\sqrt{196}[/tex], the deepest part of the pond is less than 14.
-> The depth of the pond is between 13 and 14 meters.
Or, you can just calculate [tex]\sqrt{185}[/tex] = 13.6014... (between 13 and 14)
The measurement describes the depth of the pond is Between 13 and 14 meters.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
Since one side measure 14, and the height (depth) could not be higher than 14 meters .
The length of the pond can be calculated using the Pythagorean theorem as;
length^2 = 36^2 + 14^2
length^2 = 1296 + 196
length^2 = 1492
length = 38.6 m

The hypotenuse of a right triangle measures 6cm and one of its legs measures 3cm.Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
5.2
Step-by-step explanation:
a^2+b^2=c^2
Where c is the length of hypotenuse
and a, b are lengths of the legs.
Put in 6 for c,
Put in 3 for a and you get 9+b^2=36
Subtract 9 from both sides and get b^2= 27
Then find the square root of both sides to get b, so the answer is the square root of 27.
The cloest square root is 5, then apporixmate the tenths value and see if they work.
Answer: 5.2
Answer:

Researchers are studying two different designs of computer keyboards, J and K, to investigate the effectiveness of the design on the speed of data entry. The researchers believe there is a tendency for people entering data with keyboard J to have faster entry times compared with people entering data with keyboard K. Using the same set of data for entry, the researchers randomly assigned 5 people to keyboard J and 6 people to keyboard K and recorded the number of seconds each person took to enter the data.
The following dotplots show the observed entry times for the two keyboards.
Keyboard J - 160 180 280 300 200 220 240 260 Entry Time (seconds)
Keyboard K + 160 + 180 280 300 200 220 240 260 Entry Time (seconds)
Explain why it is not appropriate to conduct a two-sample t-test for the difference in population means.
It is not appropriate to conduct a two-sample t-test because there exists an outlier in both variables.
What is a two-sample t-test?
The two-sample t-test is used to determine if two population means are equal. The purpose of the test is to determine whether the difference between these two populations is statistically significant.
In this case, it is not appropriate to conduct a two-sample t-test because there exists an outlier in both variables. Therefore, it might be more appropriate to compare population medians instead of population means.
