The probability of not choosing a black shirt is...? please explain!
Answer:
80% or 8/10.
Step-by-step explanation:
Assuming the shirts in the bottom right are the "black" shirts, there is ten total shirts (1 red, 4 blue, 2 green, 1 white, 2 black.) Out of the ten shirts, 8 are not black. This means that there is an 80% chance that you will select a shirt that is NOT black.
What is the vertex of the graph of the function f(x) = x^2 + 8x − 2 ?
a (−4, 18)
b (0, -2)
c (-8, -2)
d (−4, −18)
Answer:
The vertex is at (-4, -18) (Fourth answer choice)
Step-by-step explanation:
The standard vertex equation of a parabola is f(x) = (x - h)^2 + k.
"Completing the square" is one of the faster and better ways of determining the vertex:
f(x) = x^2 + 8x - 2 => f(x) = x^2 + 8x + 16 - 16 - 2 => (x + 4)^2 - 18. Comparing this to (x - h)^2 + k, we see that h = -4 and k = -18. The vertex is at (-4, -18).

Given the exponential equation y=34(5)x, what is the y-intercept (or starting point) of the graph?
Answer:
34
Step-by-step explanation:
Given
y = 34[tex](5)^{x}[/tex]
To find the y- intercept let x = 0, that is
y = 34[tex](5)^{0}[/tex] = 34 × 1 = 34 ← y- intercept

Step-by-step explanation:
a rectangular field has side lengths that measure 9/10 mile and 1/2 mile what is the area of the field
Answer:
[tex]\frac{9}{20}miles^2=0.45miles^2[/tex]
Step-by-step explanation:
To find the area of a rectangle:
[tex]a=l*w[/tex]
where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
In this case:
length: [tex]l=\frac{9}{10}miles[/tex]
width: [tex]w=\frac{1}{2} miles[/tex]
thus, we multiply this quantities to find the area:
[tex]a=(\frac{9}{10} miles)(\frac{1}{2}miles )\\\\a=\frac{9*1}{10*2}miles^2\\ \\a=\frac{9}{20}miles^2[/tex]
the area of this rectangle is 9/20 miles squared, or what is the same 0.45 miles squared

Answer:
The fist left
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
We need to understand what is the line of best fit
A line representing the best data on a distributed chart. This line can go through some points, no point or all points.
In the attached photo, we can see that the 1st left line is the best represent for the relationship between two variables,x and y.

If Jay has an 85 average over four exams, what would his average need to be on his
last two exams to bring his average up to an 88?
Answer:
91 average for his next exams
Step-by-step explanation:
he has an 85 right now. if he gets a 91 then his overall average will be an 88 like he wanted.
(this is how u find average) ( add them together then divide it by how many numbers there are)
85+91=176
176/2= 88
therefore the average on his next 2 exams must be
91

Determine the value of
X in the diagram below. Justify your reasoning.
Answer:
x = 70°
Step-by-step explanation:
Sum of external angles of polygon = 360
x + 150 + 140 = 360
x + 290 = 360
x = 360 - 290
x = 70°

Over a 4.5 hour period, the rain gauge collected 2.8 inches of rain. In the
next 19.5 hours it collected an additional 1.75 inches of rain. What is the
total amount of rain, in inches, that the gauge collected?
Your answer
Select all the expressions that are equivalent to 1.94
~
2.37 -0.43
Answer: 4.55 inches of rain
Step-by-step explanation: Is this a trick question? It's a lot easier than it looks...but i'll give you a step by step explanation.
So, we know is 4.5 hours it collect 2.8 inches of rain, must have been a rainy day.
The next day the gauge collect 1.75 inches of rain, it must have sprinkled a little.
2.8 + 1.75 = 4.55
Therefore, the guage collected 4.55 inches of rain in total.
I hope this helps!
