In the given figure p ∥ q , and t is a transversal then find the measures of a, b, c, d and e.
Answer:
d=125-degree since p and q are parallel
b=d=125-degree since b and d are vertically opposite angles
a+d= 180-degree since they lie in straight line
Hence, a=180-125=55-degree
c=a=55-degree since a and c are vertically opposite angle
f=a=55-degree since a and f are alternate angle
e=f=55-degree since e and f are vertically opposite angle
If f(x) = -2[x] + 8, what is f(-1.8)?
4
6
10
12
Answer:
it's 12!
Step-by-step explanation:
Answer:
C. 10
Step-by-step explanation:
First, you plug in f(-1.8) into the original equation.
f(-1.8) = -2 (-1) + 8
The reason why I rounded -1.8 to -1 is because we're using the ceiling function, which means we need to round up (the brackets tell you in Edge but not on Brainly). Rounding up a negative number means we are going closer to 0. The next whole number close to -1.8 on the right will be -1.
Now solve:
f(-1.8) = 2 + 8 = 10
The answer is 10 if f(-1.8)

A new runner has decided to purchase a new pair of running shoes. He has narrowed his choices to two brands, each of which would be appropriate for his use. His concern is whether there is a significant difference in the average wear between the two brands of shoes. He enlisted a random sample of 6 veteran runners to test the shoes. Each runner wore each brand of shoe until it wore out. What method of analysis is more appropriate to use for this problem
Answer:
Paired difference t test
Step-by-step explanation:
The paired difference t test is a type of statistical test which is used to examine if difference exists in th population mean of two samples. The paired difference test usually involves samples taken within subjects. That is, the sample mean for each set of measurement is taken from the Same subject, In the scenario described above, the subjects which are the 6 veteran runners each wore each of the two shoe brands, this means that two readings were produced by each runner ; one reading for brand A and the other brand B.
The difference between the two readings are taken for each runner and used to perform a hypothesis test:
t = μd/ (s/√n)
s = sample standard deviation ; n = sample size ; μd = mean difference
A school store has 1200 pencils in stock, and sells an average of 25 pencils per day. The manager reorders when the number of pencils in stock is 500. In how many days will the manger have to reorder? The equation that the manger uses to calculate number of days is 1200 - 25x =500.
A 35 DAYS
b 45 DAYS
C 28 DAYS
D 17 DAYS
Answer:
C. 28 DAYS
Step-by-step explanation:
You take the total ammount of pencils and subtract the minimum stock (y intercept)
1200-500 = 700
700 divided by the slope of the equation (how many pencils a day is sold) 25
700/25 = 28
16. Find the value of X (In the picture) (giving points to best answer/brainlest)
Answer:
x=46
Step-by-step explanation:
Let's call the angle near x is y
x+y = 180 - 22 -90 = 68
The right triangle is a isosceles triangle
So y=22
x+22 = 68
x = 46

5x5x5x5x5 in expression in exponential form
Answer:
5^5
Step-by-step explanation:
There are 5 fives being multiplied together.
The expression 5x5x5x5x5 can be written in exponential form as [tex]5^5[/tex].
To express the expression 5x5x5x5x5 in exponential form, follow these steps:
Step 1: Count the number of times the base (5) is multiplied by itself (the number of factors).
Step 2: Write the base (5) followed by the exponent, which is the number of factors from Step 1.
In this case, the base is 5, and it is multiplied by itself 5 times:
5x5x5x5x5 = [tex]5^5[/tex]
So, the expression 5x5x5x5x5 can be written in exponential form as [tex]5^5[/tex].

Factorize by splitting the middle term: 100 x2 – 20x + 1.
Answer:
Below;.
Step-by-step explanation:
100x^2 - 10x - 10x + 1
= 10x(10x - 1) - 1(10x - 1)
= (10x - 1)(10x - 1).
On each coordinate plane, the parent function f(x) = |x| is represented by a dashed line and a translation is represented by a solid line. Which graph represents the translation g(x) = |x + 2| as a solid line?
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, negative 2).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (negative 2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, 2).
Using shifting concepts, we get that the graph that represents the translation g(x) = |x + 2| as a solid line is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
--------------------------------------------------
Shifting a function f(x) a units to the left is the same as finding f(x + a).--------------------------------------------------
The vertex of the function f(x) = |x| is at the point where x = 0, and thus, f(x) = 0. Thus, the vertex of the dashed line is at (0,0).The vertex of the function g(x) = |x + 2| is at the point where [tex]x + 2 = 0 \rightarrow x = -2[/tex], g(-2) = |-2 + 2| = 0. Thus, the vertex of the solid line is at (-2,0).Thus, the correct option is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
At the end of the exercises, there are are the graphs of those two functions, considering the dashed line as the red line and the solid line as the blue line.

Answer:
Sydney is 45
Step-by-step explanation:
Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...
s +(s -14) = 76
2s = 90 . . . . . . simplify, add 14
s = 45 . . . . . . . divide by 2
Sydney's age is 45.
___
Check
Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.
Answer:
x + (x - 14) = 76
2x - 14 = 76
2x = 90
x = 45
Sydney is 45
45 - 14 = 31
Devaughn is 31

Points A, B, and C are collinear, BC = 2x+1, AB = 4x-3. AC is 7x- 6. What is
AB?
A line is a one-dimensional shape that is straight, has no thickness. The length of the sides AB is 13 units.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
Given Points A, B, and C are collinear, BC = 2x+1, AB = 4x-3, and AC is 7x- 6. Since the three points are collinear therefore, the sum of AB and BC will be equal to AC. Therefore, we can write,
AB + BC = AC
4x - 3 + 2x + 1 = 7x - 6
6x - 2 = 7x - 6
-2 + 6 = 7x - 6x
4 = x
Now, since the value of x is 4, the measurement of AB is,
AB = 4x - 3 = 4(4) - 3 = 16 - 3 = 13 units
Hence, the length of the sides AB is 13 units.

If d(4)=68. Thus, joe travels 68 mi in 4 hours. How many mi does Joe travel in 45 min
Answer:
12.75 miles
Step-by-step explanation:
Changing hours to minutes
4 hours 4*60 = 240 minutes
Now we can use a ratio to solve
68 miles x miles
------------- = -----------------
240 minutes 45 minutes
Using cross products
68*45 = 240x
Divide each side by 240
68*45 /240 = x
12.75 miles
Answer:
12.75 MILES
Step-by-step explanation:
if he travels 68 miles in 4 we should find how many miles per hour
to find this we divide 68/4 which is 17
So if he is going 17 MPH then to find how far he travels in 45 min we should multiply by 3/4
17 x 3/4 is 12.75
12.75 MILES
