Answer:
53.5
Step-by-step explanation:
c = the height of the first 3 boys.
c = 54 + 48.5 + 46
c = 148.5
Now you add a fourth boy. His height is h.
A(h)= (c + h)/d
d = the total number of boys which is 4.
The new average is 50.5
A = (c + h)/d
50.5 = (148.5 + h) / 4 Multiply both sides by 4
202 = 148.5 + h Now subtract 148.5 from both sides
202 - 148.5 = h
h = 53.5

Answer:
(a) $2.857 million
(b) vertical compression by 1/3; shift left by 6; shift up by 2
Step-by-step explanation:
(a) Find the year difference (2021-2010=11) and put that value where x is. Then do the arithmetic.
g(11) = (∛(11+6))/3 +2 = (∛17)/3 +2 ≈ 2.57128/3 +2 ≈ 0.857 +2
g(11) ≈ 2.857 . . . 2021 revenue in millions of dollars
__
(b) For parent function f(x), the transformation ...
g(x) = a·f(x -h) +k
represents a vertical scaling by a factor of 'a', right shift by h units, and up shift by k units.
Comparing this form to the given g(x), we see ...
a = 1/3 . . . vertical compression by a factor of 1/3
h = -6 . . . .right shift 6 units
k = 2 . . . . up shift 2 units
_____
Additional comment
The vertical scaling is called "compression" when the scale factor is less than 1, and "stretch" when the scale factor is greater than 1. Here, the scale factor of 1/3 means the graph is vertically compressed.
Write an exponential model given the two points (6,130) and (7,220).
Answer:
y=90x−410
Step-by-step explanation:
in point-slope form, this would be...

Evaluate: C(14, 10)
no pic just answer it
Given:
The combination C(14,10).
To find:
The value of the given combination.
Solution:
We know that,
[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]
Using this formula, we get
[tex]C(14,10)=\dfrac{14!}{10!(14-10)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11\times 10!}{10!(4)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11}{4\times 3\times 2\times 1}[/tex]
[tex]C(14,10)=7\times 13\times 11[/tex]
[tex]C(14,10)=1001[/tex]
Therefore, the value of C(14,10) is 1001 and the correct option is B.
The equivalent expression of "[tex]C(14,10)[/tex]" is "1001".
Equivalent expression:using formula:
[tex]\to ^n C_r=\frac{n!}{r!(n-r)!}[/tex]
putting the given value into the above formula:
[tex]\to ^{14} C_{10}=\frac{14!}{10!(14-10)!}[/tex]
[tex]=\frac{14 \times 13 \times 12 \times 11 \times 10! }{10! \times 4 \times 3 \times 2 \times 1}\\\\=\frac{14 \times 13 \times 12 \times 11 }{ 4 \times 3 \times 2 \times 1}\\\\={7 \times 13 \times 11 }{}\\\\=1001[/tex]
Therefore, the final answer is "1001".

Angle DEF is similar to angle JKL.Find the length of JL and KL? First triangle DF 12.4cm DE 4cm EF 9cm other triangle JK 3cm JL ? KL ?
Answer:
KL = 6.75cm
JL = 9.3cm
Step-by-step explanation:
SInce Angle DEF is similar to angle JKL.
Then;
DE/EF = JK/KL
Given
DE = 4cm
JK = 3cm
EF = 9cm
Substitute
4/9 = 3/KL
4KL = 27
KL = 27/4
KL = 6.75cm
Similarly
DF/EF = JL/KL
12.4cm/9 = JL/6.75
9JL = 12.4 * 6.75
9JL = 83.7
JL = 83.7/9
JL = 9.3cm

The distance in miles that some students live from school is show in the histogram which stamen about the data in the histogram is true
Answer:
D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.
Step-by-step explanation:
The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.
