Answer:
GiGi.
Step-by-step explanation:
To find GiGi's mean, add 25, 35,20, 27, 32, and 21 = 160, divide by the six games =26.66
To find Myra's, add 18, 23, 25, 35, 40, and 15 = 139, divide by the six games = 23.16
What is the vertex of y=x2 – 2x + 3?
O (-1,3)
O (1, 2)
O (3, 1)
O (2, -1)
Answer:
vertex = (1, 2 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = x² - 2x + 3 ← is in standard form
with a = 1, b = - 2 , then
x = - [tex]\frac{-2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = 1² - 2(1) + 3 = 1 - 2 + 3 = 2
vertex = (1, 2 )

Given a mean of 75 and a standard deviation of 7,
how many students out of 500 would score higher
than 68?
Answer:
421 students out of 500 would score higher than 68
Step-by-step explanation:
P(X>68) = normalcdf(68,100,75,7) = 0.841 = 84.1%
Therefore, 84.1% of 500 students is 421 (remember to round up).
There are 421 students out of 500 who would score higher than 68 if the mean is 75 and the standard deviation is 7.
What is the standard deviation?
The standard deviation mathematical and statistical analysis tool used to explain the diversity of treatments or values around the Mean is the standard deviation, which is also known as the square root of variance.
Given a mean of 75 and a standard deviation of 7,
Mean μ = 75
SD σ = 7
By using the normal distribution,
P(X > 68) = P( z > (68-μ)/σ)
P(z > 1)
By using z-table, we get
= 0.8413
Therefore, 84.1% of 500 students is 421 (rounded to the nearest integer).
Hence, 84.1% of students out of 500 would score higher than 68.

If your initial principal is $243 and your principal in 2 years is $1,359.19, how much interest did you earn?
Answer: $1,116.19
Step-by-step explanation:
If you invested $243 and this increased to $1,359.19 in two years, the difference between your investment and its current worth is the interest:
= Current principal - Initial principal
= 1,359.19 - 243
= $1,116.19
find the product of (x+2y)^2
Answer:
x^2 + 4xy + 4y^2
Step-by-step explanation:
hope this helps
Answer:
x² + 4xy + 4y²
Step-by-step explanation:
(x + 2y)²
= (x + 2y)(x + 2y)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 2y) + 2y(x + 2y) ← distribute parenthesis
= x² + 2xy + 2xy + 4y² ← collect like terms
= x² + 4xy + 4y²

Solve for r
5/12 · r = 10/11
Write your answer as a fraction or as a whole or mixed number.
r = ___
Answer:
r = 2 2/11
Step-by-step explanation:
5/12 · r = 10/11
Multiply each side by 12/5 to isolate r
(12/5) *5/12 · r = 10/11* 12/5
r = 12/11 * 10/5
r = 12/11*2
r = 24/11
r = 2 2/11
Answer:
11/24
Step-by-step explanation:
Multiply both sides of this equation by 12/5 to isolate r:
(5/12)(12/5)
r = ------------------ = 55/120
(12/5)(10/11)
r = 55/120 = 11/24

solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again

Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]

3/4 of the shirts in a store are black. 50% of the shirts are white and the remaining 12 shirts are red. How many black masks are in the store
Answer:
There are total 96 shirts out of which 72 are black and 12 are white and 12 are red.
Step-by-step explanation:
Let the total number of shirts be x.
Then 3/4= 0.75 shirts are black
50% or 50/100 =0.5 of 1/4 ( 1-3/4) remaining are white
and 12 are red
x= 0.75x+0.125x+12
x= 0.875x+ 12
x-0.875x= 12
0.125x= 12
x= 12/0.125
x= 96
There are total 96 shirts out of which 3/4 are black
96*0.75= 72 are black and
96*0.25= 24 are left behind out of which 50% are white.
12 are white and 12 are red.
Hi! Does anyone know the answer to this question? I’m bad at geometry and I’m struggling to get the answer. Please help!
Step-by-step explanation:
It is because of Angle-Angle Similarity.
Angle EDC = Angle CAB [Perpendicular, 90°]
Angle ECD = Angle ACB [Vertically Opposite Angles]
So,
Triangle ADC ~ Triangle BAC
Hope it helps :)
Answer:
Because of AA postulate
Step-by-step explanation:
[tex] In\: \triangle ABC\: \&\:\triangle DEC[/tex]
[tex] \angle CAB \cong \angle CDE[/tex] (Right angles)
[tex] \angle ACB \cong \angle DCE[/tex] (Vertical angles)

Jimmy purchased a package of jelly beans that contained 75 jellybeans. Out of the 75 jellybeans, 8 are pink, 17 are orange, 22 are red, 18 are green, 6 are white and 4 are black.Jimmy later noticed that the package of jellybeans contained a hole and two jellybeans dropped out of the package while he was walking home.
Find completion to question in comment section.
Answer:
D. One of the jellybeans that slipped out was orange and one was black
Step-by-step explanation:
We calculate the option with the highest probability of occurrence :
Total number of jellybean = 75
n(T) =75
n(Pink) = 8
n(red) = 22
n(Orange) = 17
n(green) = 8
n(white) = 6
n(black) = 4
We assume that the jelly beans must have slipped out one after the other.
Evaluating the options :
A.)
P(pink) and P(white)
8/75 * 6/74 = 0.0086486
B.)
P(green) and P(green)
8/75 * 7/74 = 0.0100900
C.)
P(white) and P(white)
6/75 * 5/74 = 0.0054054
D.)
P(orange) and P(black)
17/75 * 4/74 = 0.0122522
From the probability values obtained, the highest is D. Hence, the most likely to have occurred is One of the jellybeans that slipped out was orange and one was black
