Answer:
Ratio of coco mix to water is 2 : 3.
Step-by-step explanation:
Given that:
Lindsey used 3 cups of water to 2 tsp of coco mix to make chocolate.
Ratio is the quantitative relationship between two amounts.
Ratio of coco mix to water.
Tsp of coco mix : Cups of water
2 : 3
Hence,
Ratio of coco mix to water is 2 : 3.
180-140=40
B is 40 degrees. For further explanation on this answer, do a little research on supplementary angles.
So if you didn't know x^2 + y^2 = r^2 is the equation of a circle where the center is at the origin. It is usually written as (x-h)^2 + (y-k)^2 = r^2. So if we are moving it to the left by 8 units we write:
(x+8)^2 + (y-k)^2 = 16
Next we move it 3 units down, so we get:
(x+8)^2 + (y+3)^2 = 16
That is your answer. Hope this helps! :D
Answer: the probability that the weight will be less than 4866 grams is 0.9861
Step-by-step explanation:
Since the weights of newborn baby boys born at a local hospital are believed to have a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weights of newborn baby boys.
µ = mean weight
σ = standard deviation
From the information given,
µ = 3571 grams
σ = 589 grams
The probability that the weight will be less than 4866 grams is expressed as
P(x < 4866)
For x = 4866,
z = (4866 - 3571)/589 = 2.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.9861
