There is a bag with only milk and dark chocolates. The probability of randomly choosing a dark chocolate is 3 8 . There are 21 dark chocolates in the bag and each is equally likely to be chosen. Work out how many milk chocolates there must be.
Answer:
Number of milk chocolate in beg = 56
Step-by-step explanation:
Given:
Probability of randomly choosing a dark chocolate = 3/8
Number of dark chocolate = 21
Find:
Number of milk chocolate in beg
Computation:
Number of milk chocolate in beg = Number of dark chocolate / Probability of randomly choosing a dark chocolate
Number of milk chocolate in beg = 21 / [3/8]
Number of milk chocolate in beg = 21[8/3]
Number of milk chocolate in beg = 7[8]
Number of milk chocolate in beg = 56
Number 36 pleaseee if you can
Answer:
option 2
Step-by-step explanation:
[tex]ax^2 + bx + c = 0\\Discriminant = b^2 - 4ac[/tex]
36. a = 3 , b = 5, c = 1
[tex]Discriminant = 25 - ( 4 \times 3 \times 1) = 25 - 12 = 13[/tex]

What is the slope of the line
Answer:
-3
Step-by-step explanation:
y1-y2/x1-x2 = slope
Plug in coordinates (-1,0) and (0,-3)
-3-0/0-(-1)
-3/1
-3
Answer:
-3
Step-by-step explanation:
Pick two points on the line
(-1,0) and (0,-3)
You can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -3-0)/(0- -1)
= (-3-0)/(0+1)
= -3/1
= -3
what is the range of the function graphed below?
i honestly have no idea please help
Answer:
C
Step-by-step explanation:
The range of a graph is how far the graph goes up and down. The lower boundary is easy, as we can see that the left side of the line goes down forever, so it is negative infinity. Looking at the top of the graph, we can see that the graph never goes past y=2. So the answer is:
-∞<y<2
Children who have lost some baby teeth have better arithmetic skills than children who have not lost any baby teeth. In fact, the more baby teeth a child has lost, the better his/her arithmetic skills tend to be.
Which of the following statements is most likely true?

2. There is a correlation here, and losing baby teeth causes arithmetic skills to improve.
3. There is a correlation here, and improving arithmetic skills causes the loss of baby teeth.
4. There is a correlation here, but there is not a direct causal relationship between losing baby teeth and arithmetic skills.

Answer:
x=8
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
16 = 1/2 (4) x
16 =2x
Divide each side by 2
16/2 = 2x/2
8 =x
The height is 8 units

How can you solve for X in the proportion of7/8 equals X/24
Answer and Step-by-step explanation:
The last answer choice is correct.
Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x
The process being used in the last answer choice is called Cross multiplication, and is used to find the unknown value in fractions.
[tex]\frac{7}{8}[/tex] × [tex]\frac{x}{24}[/tex]
7 × 24 = 8x
168 = 8x
21 = x

Answer:
[tex]P(New\ House) = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
See attachment
Required
[tex]P(New\ House)[/tex]
This is calculated as:
[tex]P(New\ House) = \frac{New\ House}{Total}[/tex]
From the attachment, we have:
[tex]New\ House = 60^o[/tex]
[tex]{Total}= 360^o[/tex] --- total angle in a pie chart
Note that the measurements must be converted to degrees (if not already in degrees).
So, we have:
[tex]P(New\ House) = \frac{60}{360}[/tex]
Simplify
[tex]P(New\ House) = \frac{1}{6}[/tex]
