Hense determine the general formula for pattern B
Step-by-step explanation:
for A
[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 3 - 1 = 2 \\ an = 1 + (n - 1) \times 2[/tex]
for B
[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 9 - 1 = 8 \\ an = 1 + (n - 1) \times 8[/tex]

Which equation matches the hanger diagram?
pls help !!!
Option D is correct, 2x=5 is the equation which matches the hanger diagram.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find the equation which matches the hanger diagram.
Hanger models are a visual representation of an equation
For the hanger to remain balanced, each side has to have the same weight. Like a seesaw, a scale, or a barbell.
In the left side of hanger there 2 x's and on right side there are fives ones.
So 2x=5 is the equation which satisfies the given hanger diagram.
Hence, Option D is correct, 2x=5 is the equation which matches the hanger diagram.

In a statistics activity, students are asked to determine if there is a difference in the proportion of times that a spinning penny will land with tails up, and the proportion of times a spinning dime will land tails up. The students are instructed to spin the penny and the dime 30 times and record the number of times they land tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times.
Based on the 98% confidence interval, (–0.36, 0.22), is there evidence of a difference in proportions of tails side up for a penny and a dime?
There is convincing evidence because the two sample proportions are different.
There is not convincing evidence because the interval contains 0.
There is not convincing evidence because the interval contains both negative and positive values for the true difference.
Answer: B) There is not convincing evidence because the interval contains 0.
==============================================================
Explanation:
The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.
Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.
The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.
----------------
In short,
If the confidence interval contains 0, then you fail to reject the nullIf the confidence interval doesn't contain 0, then you reject the null.In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.

Answer:
Step-by-step explanation:
Adjacent angles must sum to 180 degrees.
x+32=180
x=148 degrees
Answer:
x= 148
Step-by-step explanation:
line CD is a straight angle which means it is 180 degree
to find x you must subtract the known angle from the straight angle
your equation should look like this
180-32=148

Answer:
it is not a function
Step-by-step explanation:
if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y
(-13,4) and (-13,9)
because you have two different y values for the same x it would fail the vertical line test and thus is not a function

write an equation to represent this function. use function notation.
Answer:
[tex]L(x) = 360 - 15 w[/tex]
Step-by-step explanation:
See comment for complete question
Given
[tex]Amount = \$360[/tex]
[tex]Rate = \$15[/tex] weekly
Required
Determine the function to represent the scenario
The amount (L) owed in w weeks is represented as:
[tex]Amount\ Owed = Amount - Rate * Weeks[/tex]
We used negative because the amount reduces weekly.
So, we have:
[tex]L(w) = 360 - 15 * w[/tex]
[tex]L(x) = 360 - 15 w[/tex]

Write the equation for the line that passes through (2, -4) and is
perpendicular to the line to x - 4y = 7.
Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2
