Answer:
82 boxes
Step-by-step explanation:
731/9 = 81 2/9
If Sarah uses 81 boxes, she will have 2 cars left over.
Sarah needs 82 boxes to hold all of her cars.
Answer:
0.34134
Step-by-step explanation:
in other to solve for this question we would be using the z score formula
z = (x - μ) / σ
x = raw score
μ = mean
σ = standard deviation
the question tells us to find the probability that a worker selected at random makes between $350 and $400
let x1 = 350 and x2= 400 with the mean μ = 400 and standard deviation σ = $50.
z1 = (x1 - μ) / σ = (350-400) / 50 = -1
z2 = (x2 - μ) / σ = (400 - 400) / 50 = (0/50) = 0
from tables, P(z <= -1) = 0.15866
P(z <= 0) = 0.5
then the probability would give us, P(-1 ≤ z ≤ 0) =0.5 - 0.15866 =
0.34134
that explains that the probability that a worker selected at random makes between $350 and $400 = 0.34134
Distance = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-2,8)....x1 = -2 and y1 = 8
(11,2)...x2 = 11 and y2 = 2
now sub
d = sqrt (11 - (-2)^2 + (2 - 8)^2
d = sqrt (13)^2 + (-6^2)
d = sqrt (169 + 36)
d = sqrt 205
d = 14.317...rounds to 14.32 <==
The answer is A B or C and possibly D
Answer:
[-6, 8]
Step-by-step explanation:
Domain: set of all possible <u>input</u> values (x-values)
Range: set of all possible <u>output</u> values (y-values)
The <u>closed circles</u> on the <u>endpoints</u> of the curve mean that those points are <u>included</u> in the interval.
From inspection of the graph, the smallest y-value is -6 and greatest y-value is 8.
To express this in <u>interval notation</u> write the beginning and ending numbers of the interval inside <u>square brackets</u> as the end values are <u>included</u>.
(If the circles were open, and therefore the end values should not be included, use curved brackets).
Therefore the range of the given graph is: [-6, 8]
