Answer:
d = 291 + n
Step-by-step explanation:
Given that,
Last week, Kira drove 291 miles. Then this week she drove n miles.
We need to find an expression for the total number of miles she drove in the two weeks. It can be calculate by adding distance force 2 weeks. So,
d = 291 + n
Hence, this is the required solution.
The weekly salaries of teachers in one state are normally distributed with a mean of $490 and a standard deviation of $45. What is the probability that a randomly selected teacher earns more than $460 a week?
Answer:
0.74751
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ, where
x is the raw score = $460
μ is the population mean = $490
σ is the population standard deviation = $45
z = 460 - 490/45
z = -0.66667
Probability value from Z-Table:
P(x < 460) = 0.25249
P(x > 460) = 1 - P(x<460)
P(x > 460) = 1 - 0.25249
P(x > 460) = 0.74751
The probability that a randomly selected teacher earns more than $460 a week is 0.74751
What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?
Answer:
{24, 18, 12, 6, 0} is the range of the above function
Step-by-step explanation:
solution:
let, x= -4
f(-2) = 12-3*(-2)
= 12+12
=24
let,x= -2
f(-2) = 12-3*(-2)
=12+6
18
let,x =0
f(0)= 12-3*0
=12-0
=12
let,x=2
f(2) = 12-3*2
=12-6
=6
let,x=4
f(4) = 12-3*4
=12-12
=0

if quadrilateral PQRS is an isoceles trapezoid if RP=12 then SQ= ?
The question is missing parts. Here is the complete question.
Quadrilateral PQRS (shown below) is an isosceles trapezoid. If RP = 12, then SQ = ?
Answer: SQ = 12
Step-by-step explanation: A trapezoid is a quadrilateral with two opposite parallel sides, called bases. The trapezoid is an isosceles trapezoid when the non-parallel sides have the same length.
One property of isosceles trapezoid is that its diagonals are congruent, i.e., have the same length.
In the picture, segment RP is one of the trapezoid's diagonal. It is asking the measure of SQ, which is the other diagonal. So:
SQ = RP
SQ = 12
Segment SQ of isosceles trapezoid PQRS is 12 units.
Answer:
if quadrilateral PQRS is an isosceles trapezoid if RP=12 then SQ= 12

how much ₹ each will get if 242.46₹ is distributed equally among the students
Complete Question:
How much ₹ will each get if 242.46₹ is distributed equally among the 6 students
Answer:
Each of the 6 students will get ₹40.41
Step-by-step explanation:
Given
[tex]Amount = 242.46[/tex]
[tex]Students = 6[/tex]
Required
Determine how much each student gets
To do this, we simply divide the total amount by the number of students
i.e.
[tex]Each\ Students = \frac{Amount}{Number\ Students}[/tex]
[tex]Each\ Students = \frac{242.46}{6}[/tex]
[tex]Each\ Student = 40.41[/tex]
Hence, each of the 6 students will get ₹40.41

which of the following equations is perpendicular to y=3/4+4 and passed through the point (6,-12)
Answer:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 4 4 . The equation of a perpendicular line to y=4x−5 y = 4 x - 5 must have a slope that is the negative reciprocal of the original slope.

Let's solve this question as simply as we can
Step 1:
Add your odd numbers which is one with one
There are many ways in which we can classify numbers, Such as using the terms odd numbers and even numbers and a example of an odd number is one as it can not be divided by 2.
ex. 1 divided by 2 = 0.5
Step 2:
Now after adding our odd number you should turn up with an even number which we know as two.
Even numbers can be divided by 2
ex. 2 divided by 2 = 1
Answer is = 2
A surgical procedure requires choosing among four alternative methodologies. The first can result in five possible outcomes, the second can result in two possible outcomes, and the remaining methodologies can each result in four possible outcomes. What is the total number of outcomes possible?
Answer:
15 possible outcomes
Step-by-step explanation:
Since each one of these methodologies are not related to one another and they do not need to be chosen in any order or consecutively then the possible outcomes would only need to be added all together to calculate the total possible outcomes. Since each outcome is independent. Therefore,
m1 = 5 outcomes
m2 = 2 outcomes
m3 = 4 outcomes
m4 = 4 outcomes
5 + 2 + 4 + 4 = 15
we can see that there are a total of 15 possible outcomes

According to a 2009 Reader's Digest article, people throw away approximately 90% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 100 grocery shoppers to investigate their behavior.
Required:
What is the probability that the sample proportion exceeds 0.84?
Answer:
0.9495
Step-by-step explanation:
We are given;
Population proportion; p = 90% = 0.9
Sample size; n = 100
Sample Proportion; p^ = 0.84
Formula to find the probability that sample proportion exceeds 0.84 is;
Z = P(p^ > 0.84) = (p - p^)/√(p^(1 - p^)/n)
Z = (0.84 - 0.9)/√(0.84(1 - 0.84)/100)
Z = -0.06/0.03666
Z = -1.64
From online z-score calculator attached, the probability is;
P(x>Z) = 0.9495
The cost of medical care abroad is often significantly less than in the United States. In 2014, the cost of knee replacement surgery in the United states was $34,000. This cost was $4000 more than four times the cost of knee replacement surgery in India. Find the cost of Knee replacement surgery in India.
Answer:
Cost in India: $7500
Step-by-step explanation:
Represent cost in India with I and cost in United States as U.
Given
[tex]U = 3400[/tex]
[tex]U = 4000 + 4 * I[/tex]
Required
Find I
Simply substitute 34000 for U in the second equation
[tex]34000 = 4000 + 4 * I[/tex]
[tex]34000 = 4000 + 4I[/tex]
Solve for 4I
[tex]4I = 34000 - 4000[/tex]
[tex]4I = 30000[/tex]
Solve for I
[tex]I = 30000/4[/tex]
[tex]I = 7500[/tex]
Hence, the cost in India is $7500
Edgardo adquirió un vehiculo a un costo de $23,970. Su vida útil es de 7 años y tiene
un valor residual de $975.
a ¿Cuánto deprecia el vehículo cada año?
b. ¿Cuál será su valor al cabo de 5 años?
c. Haz la tabla de depreciación y valor por año
Responder:
$ 3,285
$ 7545
Explicación paso a paso:
Dado que:
Costo del vehículo = $ 23,970
Valor de rescate = $ 975
Vida útil = 7 años
Depreciación por año = (costo del vehículo - valor residual) / vida útil
Depreciación por año = (23970 - 975) / 7
Depreciación por año = 22995/7
Depreciación por año = $ 3285
Valor del vehículo después de 5 años:
23970 - (3285 * 5)
= $ 7545
Año _____ valor del vehículo
1 ________ 20685
2 ________ 17400
3 ________ 14115
4 ________ 10830
5 ________ 7545
6 ________ 4260
7 ________ 975
Alice is saving her chore money in a bank account. She makes a deposit of $13 in the first month.
Then every month, she deposits $25. Alice forms a sequence of her account balance, An where n
refers to the number of months. Which of the statements are correct about this sequence?
Select all that apply.
Answer:
Option (3) and Option (5)
Step-by-step explanation:
Alice invested $13 in the first month.
Then she deposits $25 every month.
Therefore, sequence formed by the deposit will be an arithmetic sequence.
First term of the sequence will be,
[tex]A_1=13[/tex]
Since, recursive formula formula of a sequence is given by the formula,
[tex]A_n=A_{(n-1)}+d[/tex]
Where 'd' = common difference in each term of the sequence
Recursive formula for the sequence will be,
[tex]A_n=A{(n-1)}+25[/tex]
Since, explicit formula for the arithmetic sequence is represented by the formula,
[tex]A_n=A_1+(n-1)d[/tex]
where n = number of term
d = common difference
Therefore, nth term of the sequence formed will be represented by the explicit formula,
[tex]A_n=13+(n-1)25[/tex]
[tex]A_{10}=13+(10-1)25[/tex]
= 13 + 225
= 238
[tex]A_{8}=13+(8-1)25[/tex]
= 188
[tex]A_{12}=13+(12-1)25[/tex]
= 288
Therefore, Option (3) and Option (5) will be the answer.
