Answer:
y= -x -10y=mx+b
plug in -6 for y and -4 for x and - for m
-6=-(-4)+b
solve for b
b=-10
set up equation
Answer:
y=-x-10
or
y= -(x+4) - 6
Step-by-step explanation:
Point slope form:
y-y1=m(x-x1)
y+6=-1(x+4)
y= -x - 10

Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. We wish to compare the means of two populations using paired observations. Suppose that d3.125, 2.911, and n8, and that you wish to test the hypothesis below at the 10% level of significance. What decision rule would you use? : 0 against : 0
Answer:
Decision Rule
The critical region for one tailed test with 7 d.f is t > 1.415 for
H0 : ud ≤ 0 against the claim Ha: ud > 0
Step-by-step explanation:
The data given is
Population mean = ud= 0
Sample difference mean = d`= 3.125
Sample difference standard deviation = sd= 2.911
Sample size= n= 8
Formulate the null and alternate hypotheses as
H0 : ud ≤ 0 against the claim Ha: ud>0
The significance level ∝= 0.1
The degrees of freedom = n-1 = 8-1 = 7
The critical region for one tailed test with 7 d.f is t > 1.415
The test statistic is
t= d`- ud/ sd/ √n
Putting the values
t= 3.125-0 / 2.911/√8
t= 3.125/1.0292
t= 3.036
since the calculated value of t falls in the critical region we reject the null hypothesis .
The triangle shown below has an area of 20 units squared. Find the missing side if the height is 8
Answer:
5 unitsStep-by-step explanation:
Lets keep the missing side as x
And we also know that the area of Triangle is,
[tex] \frac{1}{2} bh[/tex]
So taking this into consideration we can write a linear equation like this,
[tex] \frac{1}{2} bh = 20[/tex]
Where height is 8,
[tex] \frac{1}{2} \times b \times 8 = 20 \\ 4 \times b = 20 \\ b = \frac{20}{4} \\ b = 5[/tex]
So therefore the missing side is 5

Solve for X (round to the nearest hundred)
Step-by-step explanation:
We use tangent because it uses opposite over adjacent.
So,

Matthew has a bag that contains orange chews, cherry chews, and lime chews. He
performs an experiment. Matthew randomly removes a chew from the bag, records
the result, and returns the chew to the bag. Matthew performs the experiment 24
times. The results are shown below:
A orange chew was selected 10 times.
A cherry chew was selected 11 times,
A lime chew was selected 3 times.
Answer: 13/24
Step-by-step explanation:
The experiment occurred 24 times orange or lime was selected 10+3=13
Probability the next chew will be orange or lime: 13/24

I think it’s 393.75 But not Sure can anyone confirm ? Or share the right answer
Answer:
$415.63
Step-by-step explanation:
it would have been 393.75, but he worked 5 hours overtime and got paid time and a half for it, meaning his normal pay plus half of it. (only for overtime tho).
so first calculate his normal pay:
40 × 8.75 = 350
then add overtime to it
8.75 × 5 = 43.75
43.75 × 1.5 = 65.625
65.625 + 350 = 415.625
round that and its 415.63!

Which two discontinuities does the graph show?
O jump discontinuity at x = -2; mixed discontinuity at x
O jump discontinuity at x = -2; infinite discontinuity at x
endpoint discontinuity at x = -2; mixed discontinuity
at x = 0
O endpoint discontinuity at x = -2; infinite discontinuity
at x = 0
Answer: D
Step-by-step explanation:
only answer that makes sense. one at -2 is definitely an endpoint, one at 0 is infinite because you can’t see ends aren’t indicated.

Keisha, Boris, and Jose sent a total of 126 text messages over their cell phones during the weekend. Boris sent 4 times as many messages as Jose. Jose sent 6 fewer messages than Keisha. How many messages did they each send?
Answer:
Boris=504 keisha=120
Step-by-step explanation:
First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120
A rectangular covered court has a length of 35m and a width of 20m. what
is the area of the covered court?
What is asked?
What are given?
What operation to be used?
What is the number sentence?
What is the answer?
Answer:
area of rectangle = 110 cm^2
Step-by-step explanation:
here's your solution
=> length of rectangle = 35 cm. [ given ]
=> width of rectangle = 20 cm. [ given ]
=> we need to find area ,
=> area of rectangle = 2(length + width)
=> area of rectangle = 2(35 + 20)
=> area of rectangle = 2*55 =
=> area of rectangle = 110 cm^2

What positive integer is closest to the value of the square root of 230 ?
9514 1404 393
Answer:
15
Step-by-step explanation:
Your calculator can tell you √230 ≈ 15.17. The closest integer is 15.
__
If you have memorized the squares of small integers, you know that 15² = 225 and 16² = 256. 230 is closer to 225 than to 256, so √230 will be closer to 15.
what is AC? pls help 30 points if u awnser
Answer:
C. 6
Step-by-step explanation:
ΔADC and ΔACB are similar because two of their angles are congruent (∠ACD and ∠ABC, and ∠DAC and ∠CAB)
Because the sides are similar, you can create a proportion
[tex]\frac{AC}{AD}=\frac{AB}{AC}[/tex]
substitute the given values for the sides. AD=4 and AB=4+5=9
[tex]\frac{AC}{4}=\frac{9}{AC}[/tex]
cross multiply
[tex]AC^{2} =36[/tex]
take the square root of both sides
AC=6
