Diana is training for a marathon. The total miles she runs varies from week to week but follows the pattern described in the table. At the beginning of her training, Diana limited her distance so that she did not run more than 10 miles during the first three days of the week. Write an inequality you can use to find the possible distances Diana may have run on Monday during the first week of training. Solve the inequality Describe the reasonable solutions
Answer:
The inequality 3x-(x-1)>5 represents this situation. Since Diana can run more than 1 mile on tuesday and more than 6 miles on sunday.

In a law office, the average number of billed hours per day was 150 last year. In the first 85 days of this year, the average number of billed hours per day is 158 with a standard deviation of 65 hours. When testing the hypothesis (at the 10% level of signficance) that the average number of billed hours per day has increased, what is the null and alternative hypotheses (please write out the null and alternative hypotheses below AND on your scratch work...failure to do BOTH will result in 0 points)
Answer:
There isn't enough evidence to reject H0
Step-by-step explanation:
Null hypothesis :
H0: μ = 150
H1 : μ > 150
Decision region :
Reject Null if ;
Pvalue < α
Zstatistic = (x - μ) / (s/sqrt(n))
Zstatistic = (158 - 150) / (65/sqrt(85))
Zstatistic = 0.1135
Using the P value calculator from Zstatistic at 90% ; α = 0.10 confidence interval ; one tailed test = 0.128
Pvalue = 0.128
Since ; 0.128 > 0.10
Pvalue > α
We cannot reject H0:
use elimination metho to solve the system of equations
Answer:
There are infinitely many solutions.
Step-by-step explanation:
3x + 2y = 7
-9x - 6y = -21
Now multiply the first equation by 3
3 × 3x + 2y = 7 ➡ 9x + 6y = 21 Now subtract second equation from first equation
9x + 6y - 9x - 6y = 21 - 21
0 = 0
The equation has infinitely many solutions meaning whatever value you write instead of x and y there will be solution.

(a) Angela and Barbra decided to start a business together. Angela invested $24000 and Barbara invested
$16000. They share all profits in the same ratio as the money was invested. they made a
total profit of $15000 at the end of the year, how much money did each person recieve?
(b) sum of money is shared among two friends in the ratio 4:9. If the smaller amount is $560, find the
larger amount.
(c) The sum $4500 is divided among Anesha, Sian and Joanne. Sian received half, Anesha received $1050
and Joanne recieved the remainder. Calculate:
i. Sian's share
ii. Joanne's share
iii. The ratio in which the $4500 was divided among the three persons in simplest form.
9514 1404 393
Answer:
(a) A : B = $9000 : $6000
(b) $1260
(c) A : S : J = $1050 : $2250 : $1200 = 7 : 15 : 8
Step-by-step explanation:
(a) The investment ratio is ...
Angela : Barbara = 24000 : 16000 = 3 : 2
The profit of 15,000 goes 3/(3+2) = 3/5 to Angela, and 2/5 to Barbara:
Angela's share: (3/5)($15,000) = $9,000
Barbara's share: (2/5)($15,000) = $6,000
__
(b) We can multiply the ratio by $140 to see the larger amount:
4 : 9 = ($140)(4) : ($140)(9) = $560 : $1260
The larger share is $1260.
__
(c) Sian gets (1/2)($4500) = $2250. Anesha gets $1050. So Joanne gets ...
$2250 -1050 = $1200
Then the shares are ...
i. Sian: $2250
ii. Joanne: $1200
iii. Ratios: A : S : J = 105 : 225 : 120 = 7 : 15 : 8

54 1/2-42 3/4
45 3/8- 13 3/4
Answer:
11 3/4
31 5/8
Step-by-step explanation:
1. 54 1/2 - 42 3/4
= 109/2 -171/4
= 218-171/4
= 47/4
= 11 3/4
2. 45 3/8 - 11 3/4
= 363/8 -55/4
= 363-110/8
= 253/8
= 31 5/8

How many times does the line y=-6 intersect with the circle x^2+y^2=36?
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
[tex]x^2 + y^2 = 36[/tex]
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when [tex]y = -6[/tex]
So
[tex]x^2 + y^2 = 36[/tex]
[tex]x^2 + (-6)^2 = 36[/tex]
[tex]x^2 + 36 = 36[/tex]
[tex]x^2 = 0[/tex]
[tex]x = 0[/tex]
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.

A directed line segment AB with A (1,3) and B (8,4) is partitioned by point C such that AC and CB form a 4:1 ratio. Find C
Write your answer as a coordinate point.
Do not include spaces in your answer.
Write your answer as a decimal if necessary.
Answer:
[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]
Step-by-step explanation:
Given
[tex]A = (1,3)[/tex]
[tex]B = (8,4)[/tex]
[tex]AC : BC = 4 : 1[/tex]
Required
Determine the coordinates of C
To do this, we make use of:
[tex]C = (\frac{nx_1 + mx_2}{n+m},\frac{ny_1 + my_2}{n+m})[/tex]
Where:
[tex]A = (1,3)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]B = (8,4)[/tex] ---- [tex](x_2,y_2)[/tex]
[tex]m:n = 4 : 1[/tex]
So:
[tex]C = (\frac{1 * 1 + 4*8}{1+4},\frac{1*3 + 4*4}{1+4})[/tex]
[tex]C = (\frac{33}{5},\frac{19}{5})[/tex]
