Answer:
B. y= -4x + 28
Step-by-step explanation:
To find the equation of this line first put it into slope-point form, [tex]y-y_{1} =m(x-x_{1})[/tex] where [tex]y_{1}[/tex] and [tex]x_{1}[/tex] are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,
First, distribute the -4
y-8=-4x+20
Next, add 8 to both sides
y=-4x+28

Della bought 3 new dresses for a total cost of $203. The
sales tax was 7.5%. What is the best estimate for the
amount of sales tax?
Answer:
$15.23
Step-by-step explanation:
Why do we
call fractions
such as 8/6
improper.
Please help
Answer:
Because the numerator cannot be higher than the denominator
Step-by-step explanation:
8/6 would be counted as incorrect bc the numerator (8) cannot be higher than the denominator (6). so it would be written as 1 2/6

Simplify the following: 6i^3 +4j^2 -6i
Please show work
Answer:
Concept: Vectors
I think the confusion here might be the usage of i and j Just to let you know, i=x and j=y So let's use that fact to conceptualize this 6x^3+4y^2-6x We can simplify by applying a common factor 2(x^3+2y^2-3x) Thats the most we can simplify thisplease help asap no trolls!
Answer:
[tex]D. These\ triangles\ cannot\ be\ proven\ congruent[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\TU=SQ\\TP=PQ\\\angle TPU= \angle SPQ [Vertically\ Opposite\ Angles\ Are\ Equal]\\Hence,\\As\ we\ are\ given,\ 2\ sides\ and\ 1\ angle\ of\ each\ triangle\ correspond,\ we\\ could\ use\ the\ SAS\ Congruency Rule.\\But:\\[/tex]
As SAS Congruency Rule tells us that 'Two triangles are congruent only if two sides and an included angle of one triangle corresponds to two sides and an included angle of the other' .
Here,
As ∠TPU and ∠SPQ are NOT the included angle of ΔTUP and ΔSPQ respectively, the two triangles cannot be proven congruent through SAS Congruency.
Note: We also cannot apply SSA congruency as SSA congruency doesnt exist.
what means ratio with explanation
What is this? Please answer with an explanation
Answer:
No
Step-by-step explanation:
Given
f(x) = [tex]\sqrt{x-10}[/tex] + 11 ← substitute x = 1
f(1) = [tex]\sqrt{1-10}[/tex] + 11
= [tex]\sqrt{-9}[/tex] + 11
[tex]\sqrt{-9}[/tex] is not real and therefore x = 1 does not have a real output for f(x)

A soda pop manufacturer runs a contest and places a winning bottle cap on every sixth bottle. If a person buys the soda pop, find the probability that the person will win for the first time on his third purchase.
Answer:
[tex]\dfrac{25}{216}[/tex]
Step-by-step explanation:
From the given information:
The probability (p) of winning a bottle cap = [tex]\dfrac{1}{6}[/tex]
The probability of not winning a bottle cap will be (q) = 1 - p
[tex]= 1- \dfrac{1}{6}[/tex]
[tex]= \dfrac{5}{6}[/tex]
Since we are told that the winning is placed once on every sixth bottle
Then the required probability = P( of not winning the first purchase) × P( of not winning the second purchase) × P( of winning the third purchase)
[tex]= \dfrac{5}{6} \times \dfrac{5}{6} \times \dfrac{1}{6}[/tex]
[tex]= \dfrac{25}{216}[/tex]

what 1/3 X 1/6 in simplest form?
1/18 would be your answer because 3 * 6 = 18. so 18 is your denominator. 1 * 1 is still 1 so that would be your numerator. You cant simplify the numerator because it's a one and can't be simplified by any other number but 18 can be simplified but it wouldn't make sense to just simplify the denominator and not the numerator so It would stay as 1/18.

Answer:
Option B: 1.3 hours is the correct answer.
Step-by-step explanation:
Given that:
Total distance = 140 miles
Speed on city roads = 35 miles per hour
Time travelled = 1.5 hours
Distance covered on city roads:
[tex]Distance = Speed * Time\\Distance = 35 * 1.5\\Distance = 52.5 miles[/tex]
Distance travelled on highway = Total distance - Distance on city roads
Distance travelled on highway = 140 - 52.5 = 87.5 miles
Speed on highway = 65 miles per hour
Time = [tex]\frac{Distance}{Speed}[/tex]
[tex]Time =\frac{87.5}{65}\\Time = 1.3\ hours[/tex]
Hence,
Option B: 1.3 hours is the correct answer.

N is an integer.
Write the values of n such that -15<3n≤6
Answer:
n = - 4, - 3, - 2, - 1, 0, 1, 2
Step-by-step explanation:
Given
- 15 < 3n ≤ 6 ( divide the 3 intervals by 3 )
- 5 < n ≤ 2
Thus n ≠ - 5 but n can equal the upper limit of 2
Hence
n = - 4, - 3, - 2, - 1, 0 , 1, 2

a hummingbird egg's mass
Answer:
A hummingbird eggs mass is approximately 0.374 mg.
Answer:
Hummingbird Nesting Habits. First of all, we must remember that there are about 17 species of hummingbirds found in the US and not all of these different species have the same nesting habits. The most prominent difference lies in their choice of location for the nest (but more on this later), nevertheless there is not much difference in the way they build their nests and tend to their young.

How many groups of 1/3 inch are in 3/4 inch?
Answer: There are 2 1/4 groups of 1/3 inch in 3/4 inch.
Step-by-step explanation:
1. Find a common denominator. 3 and 4 are both multiples of 12, so 12 would be the common denominator.
2. Convert each fraction to have the common denominator of 12.
1/3 * 4/4 = 4/12
3/4 * 3/3 = 9/12
3. Divide using the keep, change, flip method.
9/12 * 12/4 = 108/48
108/48 = 2 1/4
In 2003, the average combined SAT score (math and verbal) for college-bound students in the United States was 1026. Suppose that approximately 45% of all high school graduates took this test and that 100 high school graduates are randomly selected from among all high school grads in the United States. Which of the following random variables has a distribution that can be approximated by a binomial distribution? Whenever possible, give the values for n and p.
a. The number of students who took the SAT
b. The scores of the 100 students in the sample
c. The number of students in the sample who scored above average on the SAT
d. The amount of time required by each student to complete the SAT
e. The number of female high school grads in the sample
Answer:
The random variables which has a distribution that can be approximated by a binomial distribution is:
c. The number of students in the sample who scored above average on the SAT.
Step-by-step explanation:
The binomial distribution in this scenario will be between the number of students in the sample who scored below average on the SAT and the number of students who scored above average. Variables that have a binomial distribution must meet these four conditions:
1: The observed number of students who sat for the SAT 'n' is not variable.
2: Each student's score (observation) is purely independent of each other, either above or below average scores.
3: Each student's score (observation) shows one of the two outcomes ("success" or "failure"). Those below average are "failures." Those above average are "successes."
4: The outcome probability of "success" 'p' for each student is the same.
