Answer:

m<2= 48

m<3= 52

m<4= 48

Step-by-step explanation:

the opposite of 1 is 3 so 3 is 52 bc opposite angles have the same degree

to find angle 4 you subtract 90 by 52 bc 90 is the total for angle 1 and 4

to find angle 2. u find the opposite of it which is 42 and like i said opposite angles have the same degree

hope this helps

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both

dalvyx [7]

Answer:

9/25

Step-by-step explanation:

Number of student who has cat , dog = 25 - 3 = 22

Number of students who has cat and dogs = (15 + 16) - 22

= 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

Number of students who has only dogs = 16 - 9 = 7

P(Cat & dog) = 9/25

If y varies directly as x and z and y=4 when x=6 and z=1 find y when x=7 and z=4

yawa3891 [41]

Answer-

The value of y is $\dfrac{56}{3}$ when x=7 and z=4.

Solution-

As given in the question, y is directly proportional to x, so

$y\propto x$ -----------------1

And also y is directly proportional to z, so

$y\propto z$ -----------------2

Combining equation 1 and 2,

$\Rightarrow y\propto x.z$

$\Rightarrow y=k.x.z$

Where,

k = proportionality constant

When x=6 and z=1, y=4. Putting theses values,

$\Rightarrow 4=k\times 6\times 1$

$\Rightarrow 4=6k$

$\Rightarrow k=\dfrac{4}{6}$

$\Rightarrow k=\dfrac{2}{3}$

Now, we have to find the value of y, when x=7 and z=4

$\Rightarrow y=\dfrac{2}{3}\times 7\times 4$

$\Rightarrow y=\dfrac{56}{3}$

Therefore, the value of y is $\dfrac{56}{3}$ when x=7 and z=4.
