Mathematics
1 answer:
lyudmila [28]2 years ago
3 0

Answer: 60

Step-by-step explanation:

If the entire blue length is 100 and one of the parts of that is 64, the other part is 36.

So by the geometric mean theorem, letting the length of the dotted altitude be y,

\frac{64}{y}=\frac{y}{36}\\y^{2}=64 * 36 =2304\\y=48

So if y=48, by the Pythagoreanx=\sqrt{48^2 + 36^2}=60 theorem,

For a population with a mean of u = 40 and a standarddeviation of o = 8, find the z-score corresponding toeach of the following
ivann1987 [24]

Solution:

Given the mean and standard deviation;

\mu=40,\sigma=8

The z-score formula is;

z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

(a)

\begin{gathered} x=34,n=1 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{1}}} \\  \\ z=-0.75 \end{gathered}

(b)

\begin{gathered} x=34,n=4 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{4}}} \\  \\ z=-1.5 \end{gathered}

(c)

\begin{gathered} x=34,n=16 \\  \\ z=\frac{34-40}{\frac{8}{\sqrt{16}}} \\  \\ z=-3 \end{gathered}

The function C(t) = 400 + 30t models the number of classrooms, C. in the town of Sirap, t years from
maks197457 [2]

Answer:

1) S(t) = C(t) × D(t)

2) S(t) = (400 + 30t)(25 + t)

Step-by-step explanation:

The function C(t) = 400 + 30t ........... (1), models the number of classrooms, C. in the town of Sirap, t years from  now.  

The function D(t) = 25 + t ......... (2) models the number of students per classroom, D, t years from now.

Then if S(t) represents the number of students in Sirap's school system t years from now, then, we can write the relation  

1) S(t) = C(t) × D(t) (Answer)

2) Hence, the formula of S(t) in terms if t is given by  

S(t) = (400 + 30t)(25 + t) (Answer)

As a Question How many Students on here use Acellus?
UkoKoshka [18]
Slew lines are lines that don’t intersect (or cross over one another) and don’t lie on the small plane. So for an example, if you pick a line on the floor and a line on one of the walls, they would be skew lines because they are on different planes. It they also can’t intersect each other.
