PLEASE HELP MEEEEE ME ME MEEE​

Mathematics
1 answer:
Amiraneli [1.4K]3 years ago
4 0

Answer:

1\:\mathrm{year} (one solution)

Step-by-step explanation:

Let Ali's and Ahmet's ages be 3 and 4, respectively.

We have:

\frac{3+x}{4+x}=\frac{4}{5}

Solving for x:

5(3+x)=4(4+x),\\15+5x=16+4x,\\x=\boxed{1}

*Since the question only stipulates that Ali and Ahmet have an age ratio of 3:4, there are multiple solutions to this question.

The mean number of daily surgeries at a local hospital is 6.2. Assume that surgeries are random, independent events. (a) The cou
Scilla [17]

Answer:

a) correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

b) probability for only 2 or less than 2  surgeries  in a given day is 0.0536

Step-by-step explanation:

Given data:

mean number is given as 6.2

correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

we know that variance is given as\sigma^2 = mean = 6.2

hence, standard deviation is given as \sqrt{6.2} = 2.48998

thus standard deviation is 2.49

correct option is

Poisson distribution is 6.2 and standard deviation is 2.49

b) probability for only 2 or less than 2  surgeries  in a given day is

P(X \leq 2) = P(X =0) + P(X =1) + P(X =2)

                 = \frac{e^{-6.2} 6.2^0}{0!} +\frac{e^{-6.2} 6.2^1}{1!} +\frac{e^{-6.2} 6.2^2}{2!}

                 = 0.002029 + 0.012582+ 0.039006

                 = 0.053617

                = 0.0536

I only need help with number 9 plz
Varvara68 [4.7K]

Answer:

<h2>Letter C</h2>

Step-by-step explanation:

If we look on the number line we see that there is a point on -3, another point on -1, 2, and 7.

These points tell us our answer, but the question states it doesn't have to be in any order.

As we look at answer A we see -3, 1, 2, and -7. That's incorrect since there is no positive 1 nor an -7.

As we look at answer B we see -3, 7, 1, and -2. That's incorrect since there is no positive 1, and not a -2.

As we look at answer D we see -2, 3, 1, and 7. That's incorrect since there is no positive 2, no positive 3, and no negative 1.

C has to be the correct answer since it's the only answer left and has the 4 numbers that are on the number line.

Therefore, the correct answer is C.

Best of Luck to you.

Answer:

I am not sure .but i will try

i think so i will give correct answer

perpendicular of triangle is 22-10 cm =12 cm bcz both sides of triangle are equal =22

area of rectangle l×w= 22×17=374

area of triangle =h×b/2 Now we r not having h

lets find it

use pythagorus theorum (h2=P2+b2....2 here is square)

h=22.5cm

22.5×19=427(area of triangle )

374+427=801cm sq

i tried my best dont know its righr of wrong

pls mark me as brainlieast
