Which number line and equation show how to find the distance from 2 to 5?
Fifteen bicyclists entered a race. In how many different orders can the top five finish so that awards can be given?
pls help !!
Answer:
They can finish the race in 15 x 14 x 13 x 12 x 11 = 360360 order.
Step-by-step explanation:
There are 15 bicyclists in the race. The first position would come from the first bicyclist to the 15th. Meaning the first position can be occupied by 15 individuals. The second position can only be occupied by 14 individuals since one person is already first. Same way the third, fourth and fifth positions can be occupied by 13, 12 and 11 individuals respectively.
Therefore, they can finish the race in
15 x 14 x 13 x 12 x 11 = 360360 order.

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.
Answer:
1170 seats
Step-by-step explanation:
Given
[tex]Seats = 6500[/tex]
From the computer program, we have:
[tex]Sample = 200[/tex]
[tex]Voucher = 36[/tex]
First, we calculate the proportion (p) of those that bought the voucher
[tex]Proportion = \frac{Voucher}{Sample}[/tex]
[tex]p = \frac{36}{200}[/tex]
[tex]p = 0.18[/tex]
Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:
[tex]Estimate= Proportion * Seats[/tex]
[tex]Estimate= 0.18 * 6500[/tex]
[tex]Estimate= 1170[/tex]
The sum of two numbers is 17 and their product is 72. Find the smaller number.
=========================================
Explanation:
Through guess and check, we find that
8+9 = 17
8*9 = 72
We see that 8 is the answer.
--------------------
Another approach:
Let m and n be the two numbers.
They sum to 17 which leads to m+n = 17. Solving for n gets us n = -m+17.
Their product is 72, so, m*n = 72
Apply substitution and we get the following:
m*n = 72
m*(-m+17) = 72
-m^2 + 17m = 72
-m^2 + 17m - 72 = 0
-1(m^2 - 17m + 72) = 0
m^2 - 17m + 72 = 0
Now apply the quadratic formula
[tex]m = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\m = \frac{-(-17)\pm\sqrt{(-17)^2-4(1)(72)}}{2(1)}\\\\m = \frac{17\pm\sqrt{1}}{2}\\\\m = \frac{17\pm1}{2}\\\\m = \frac{17+1}{2} \ \text{ or } \ m = \frac{17-1}{2}\\\\m = \frac{18}{2} \ \text{ or } \ m = \frac{16}{2}\\\\m = 9 \ \text{ or } \ m = 8\\\\[/tex]
If m = 8, then n = -m+17 = -8+17 = 9.
If m = 9, then n = 8 through similar steps.
We see the two values are 8 and 9, the smaller of which is 8.
It’s an inequality I need the work for it ik the answer
Answer:
Solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]
Step-by-step explanation:
We need to solve the inequality: [tex]1<\frac{a+7}{-2}[/tex]
We need to solve the inequality, to find the value of a.
Solving the inequality:
[tex]1<\frac{a+7}{-2}[/tex]
First step is Switching both sides (the inequality will be reversed)
[tex]\frac{a+7}{-2}>1[/tex]
The next step is to multiply both sides by -2 and reverse the inequality
[tex]\frac{a+7}{-2}*-2<1*-2\\a+7<-2[/tex]
Now, subtracting 7 on both sides
[tex]a+7-7<-2-7\\a<-9[/tex]
So, solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

1/4(-16x+8) simplified
Answer:
-4x+2
Step-by-step explanation:
1/4(-16x+8)
-16x+8/4
-8(2x-1)/4
-8(2x-1)/4
-2(2x-1)
-4x+2
The simplified form of 1/4(-16x+8) will be -4x+2.We will use the arrthmetic operation to find the simplified value.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that,
1/4(-16x+8)
The order of operations is a rule that specifies the right procedure to follow when evaluating a mathematical equation. Using the acronym PEMDAS, we can memorize this order: parentheses, exponents, multiplication, and division (left to right), addition and subtraction (from left to right).
=1/4(-16x+8)
= -16x+8/4
=- -8(2x-1)/4
= -8(2x-1)/4
=- -2(2x-1)
= -4x+2
Thus, the simplified form of 1/4(-16x+8) will be -4x+2.We will use the arrthmetic operation to find the simplified value.
