What is the equation of the line that passes through the point (-6, -6) and has a
slope of - 1/3
Answer:
The equation of the line is [tex]y = -\frac{1}{3}x - 8[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Slope of - 1/3
This means that [tex]m = -\frac{1}{3}[/tex]
So
[tex]y = -\frac{1}{3}x + b[/tex]
Through the point (-6, -6)
This means that when [tex]x = -6, y = -6[/tex]. So
[tex]y = -\frac{1}{3}x + b[/tex]
[tex]-6 = -\frac{1}{3}(-6) + b[/tex]
[tex]b + 2 = -6[/tex]
[tex]b = -8[/tex]
The equation of the line is [tex]y = -\frac{1}{3}x - 8[/tex]

Iodine-131 has a half-life of 8 days. How much would be left of an original 40 g sample after 40 days?
a) 32g
b) 8g
c) 131g
d) 1.25g
e) 0.8g
Answer:
d) 1.25 g
Step-by-step explanation:
If it has a half life of 40 days, there will be 5 half-lives in that span of time so if you divide 40 by 2, 5 times or just [tex]\frac{40}{2^{5} }[/tex], it will equal 1.25.
[tex]\frac{40}{2}=20\\[/tex]
[tex]\frac{20}{2} =10[/tex]
[tex]\frac{10}{2} =5[/tex]
[tex]\frac{5}{2} =2.5\\[/tex]
[tex]\frac{2.5}{2} =1.25[/tex]
Answer: 1.25g

If 70% of a number is 126 and 95% of the same number is 171, find 25% of that number.
Answer:
45
Step-by-step explanation:
70%=126
100%=?
100×126=12600÷70
=180
100=180
25=?
25×180÷100
=45
The following information was obtained from independent random samples taken of two populations. Assume normally distributed populations with equal variances. Sample 1 Sample 2 Sample Mean 45 42 Sample Variance 85 90 Sample Size 10 12 The 95% confidence interval for the difference between the two population means is (use rounded standard error) a. -2.65 to 8.65. b. -5.344 to 11.344. c. -5 to 3. d. -4.86 to 10.86.
Answer:
95% Confidence Interval is; ( -5.344 to 11.344 )
Option b) -5.344 to 11.344 is the correct answer
Step-by-step explanation:
Given the data in the question;
Sample 1 Sample 2
x"₁ = 45 x"₂ = 42
S₁² = 85 S₂² = 90
n₁ = 10 n₂ = 12
df = [ S₁²/n₁ + S₂²/n₂ ]² / [ ((S₁²/n₁)²/n₁-1) + ((S₂²/n₂)²/n₂-1)) ]
we substitute
df = [ 10/10 + 90/12 ]² / [ ((85/10)²/10-1) + ((90/12)²/12-1)) ] = 19.64 ≈ 20
df = 20
with 95% confidence interval
∝ = 1 - 0.95 = 0.05
∝/2 = 0.05/2 = 0.025
now, [tex]t_{\alpha /2,df} = t_{0.025, 20} = 2.086[/tex] { from table }
95% confidence interval for N1 - N2
⇒ (x"₁ - x"₂) ± [tex]t_{\alpha /2,df}[/tex] × √( S₁²/n₁ + S₂²/n₂ )
⇒ (45 - 42) ± 2.086 × √( 85/10 + 90/12 )
⇒ 3 ± 2.086 × 4
⇒ 3 ± 8.344
so;
Lower Limit = 3 - 8.344 = -5.344
Upper Limit = 3 + 8.344 = 11.344
Therefore, 95% Confidence Interval is; ( -5.344 to 11.344 )
Option b) -5.344 to 11.344 is the correct answer

It takes 7 gardeners 8 hours to plant 1 680 seedlings on a piece of land.
Calculate (in hours and minutes) how long it would take 12 gardeners to
plant the seedlings
Answer:
4 hours, 40 minutes
Step-by-step explanation:
1680 ÷ 8 hours = 210 seeds per hour for 7 gardeners
30 seeds per hour per gardener
30 x 12 = 360 seeds per hour for 12 gardeners
4.66 hours to plant. which is 4 hours and 40 minutes
Find the slope and the y-intercept of the graph of the linear equation y=-7x+3
Answer:
The slope is -7 . The y intercept is (0 , 3)
Answer:
x= -1/7y+3/7
Step-by-step explanation:
step 1: −7x+3=y
Step 2: Add -3 to both sides.
−7x+3+−3=y+−3
−7x=y−3
Step 3: Divide both sides by -7.
The golf club can send a team of six students to the next golf tournament if there are 23 students in the club how many different teams of six can be selected.
I need help!!!
Answer:
3 teams.
Step-by-step explanation:
1 team = 6 students
23 ÷ 6 = 3.8333
Since it ends up being a decimal, the nearest number would be 3 because 23 teams isn't enough for 4 teams.
Five friends went to the zoo.
• Tickets cost $8.50 each.
• Each person purchased a drink for $3.50
• Three of the people had a discount coupon for $2.50 off the cost of admission,
• The friends split the total cost equally.
How much did each person spend?
А A
$10.13
B. $10.50
c С
$11.50
D
$12.00
Answer:
B . 10.50
Why ? Because 8.50+3.50=12 , Then 12 × 5 = 60 , 2.50×3=7.5 , 60-7.5= 52.5 . divide 52.5 by 5 = 10.50 . So each friend paid 10.50

Two shops, Tisco and Azda, sell the same brand of baked beans with the following deals.
Calculate the price per 20 items.
Write down which shop is the best value in the comment box.
Tisco= 4 for £1.04
Azda= 5 for £1.35
Answer:
Tisco shop
Step-by-step explanation:
The computation is shown below;
For tisco,
= 20 ÷ 4 × £1.04
= £5.2
For Azda,
= 20 ÷ 5 × £1.35
= £5.4
As if we can see that the tisco cost is lower than the azda cost so here the best value represent the tisco shop
