Answers
Step-by-step explanation:
to make it easier we bring it to the pure y = ax + b form.
y + 1 = 7/8 x
y = 7/8 x - 1
x = -2
y = (7/8 × -2) - 1 = -7/4 - 1 = -7/4 - 4/4 = -11/4
x = 0
y = (7/8 × 0) - 1 = 0 - 1 = -1
x = 1
y = (7/8 × 1) - 1 = 7/8 - 1 = 7/8 - 8/8 = -1/8
x = 8/7
y = (7/8 × 8/7) - 1 = 1 - 1 = 0
x = 2
y = (7/8 × 2) - 1 = 7/4 - 1 = 7/4 - 4/4 = 3/4

Celine has earned the following homework scores in her history class: 5, 0, 4, 8, 10, 9, 4, 6, 2. There is one homework assignment to go and Celine needs a homework average of at least 8. If each homework assignment is worth a maximum of 10 points, can she achieve her needed average?
Answers
Answer:
She can not achieve her average.
Step-by-step explanation:
For her homework average to be 8 or above, she needs to have at least 80 total points to be divided among 10 assignments.
If you add up all the values, 5, 0, 4, 8, 10, 9, 4, 6, 2, you would get 48.
She can not achieve her average because even with the maximum amount of points, 10, 58 is still less than 80.
Answer:
No

Most of her scores are under 50 or 50

Samira and Sonia each have a bag containing 20 sweets. In each bag, there are 5 red, 6 green and 9 yellow sweets.
(a)
(b)
Samira chooses one sweet at random from her bag.
Write down the probability that she chooses a yellow sweet.
[1] Sonia chooses two sweets at random, without replacement, from her bag.
(i) Show that the probability that she chooses two green sweets is 3 . 38
(ii) Calculate the probability that the sweets she chooses are not both the same colour.
Answers
Step-by-step explanation:
there must be some typos here. but I try to address the right issues.
there is nothing under (a). so, really nothing to answer.
(b)
there are 20 sweets in her bag. 9 if the 20 are yellow.
so, the probability is the ratio of desired possibilities vs. total possibilities.
that is, tada! 9/20
that is the probabilty for Samira to pick a yellow sweet.
[1] (i)
again, 20 sweets to start with.
6 are green.
when she picks the first one, her probability to pick a green one is 6/20 = 3/10 = 0.3
and now, under the assumption that this came true, she picks another sweet.
this time she had only 19 left, and 5 of them are green.
so, this probabilty is 5/19
now both events need to happen for the case we are discussing. there is no overlapping, no ors, ifs and buts. it is just the product of both probabilities.
3/10 × 5/19 = 15/190 = 3/38
I think that is what the description asks for.
(ii)
that probability is
first selection is red and second is not red +
first selection is green and second is not green +
first selection is yellow and second is not yellow
so,
red and not red
5/20 = 1/4 red
15/19 not red (there are still 15 sweets of other colors in the bag, but again now only 19 total).
red and not red = 1/4 × 15/19 = 15/76 = 0.1974
green and not green
6/20 = 3/10 = green
14/19 = not green
green and not green = 3/10 × 14/19 = 52/190 = 26/95 =
= 0.2737
yellow and not yellow
9/20 = yellow
11/19 = not yellow
yellow and not yellow = 9/20 × 11/19 = 99/380 = 0.2606
so, now assuming up all 3 possibilities ("or" = sum) gives us the general possibility of selecting two different colors
= 0.7316
Jillian bought 3 pounds of apples for $3.09 per pound. she then bought 6 pounds of peanuts for $0.87 per pound. How much did Jillian spend all together?
Answers
Answer:
Jillian spent $14.49 altogether.
Step-by-step explanation:
Let a = pounds of apples, p = pounds of peanuts, and t = total cost
t = 3.09a + 0.87p
t = 3.09(3) + 0.87(6)
t = 9.27 + 5.22
t = 14.49

Find the slope (rate of change) of each representation. Please explain how you got it.
Answers
Answer:
m = -3/2
Step-by-step explanation:
To find the slope of the representation, use the slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
I'll pick (-4, 9) and (-2, 6) in this instance.
[tex]m=\frac{9-6}{-4-(-2)}\\\\m=-\frac{3}{2}[/tex]
Therefore, the slope of the representation is -3/2.
Answer:
-3/2
Step-by-step explanation:
To find the slope, we can use the formula
m = ( y2-y1)/(x2-x1)
= ( -6 -9)/(6 - -4)
= (-6-9)/(6+4)
-15/10
-3/2
