What is the slope and y intercept of -5x+3y=-9

Mathematics
1 answer:
Irina-Kira [14]3 years ago
7 0

Answer:

slope = 5/3

y-intercept = (0,-3)

Step-by-step explanation:

Make the equation in slope-intercept form:

-5x+3y=-9

add 5x on both sides

3y=5x-9

divide by 3 on both sides

y=5/3x-3

slope = 5/3

y-intercept = (0,-3)

The expression P(4, 3) is equal to:<br> -3!<br> -4!<br> - 1
nexus9112 [7]

Answer:

P(4,3) = 4!

Step-by-step explanation:

Given

P(4,3)

Required

Solve

Using permutation formula;

P(n,r) = \frac{n!}{(n-r)!}

This implies that

P(4,3) = \frac{4!}{(4-3)!}

P(4,3) = \frac{4!}{(1)!}

P(4,3) = \frac{4!}{1!}

P(4,3) = \frac{4!}{1}

P(4,3) = 4!

In a store, a sample of 60 pens was selected from a box of 1,200 pens. Of these 60, 4 pens did not work. About how many pens cou
Lapatulllka [165]
Ok so if 1200 total pens and 60 were taken that's a ratio of 1200/60=20

out of 60pens 4 didn't work, again ratio is 4/60=1/15 so about 1/15 of the pens didn't work. 

so we have 1200pens * 1/15broken ratio = 80 pens or we can say 

20*4=80pens won't work from 20 groups of 60 and 4 out of 60 not working is 20*4=80 not working from total batch of 1200.

hope this helps you some! thank you!!!!!!!!!

Mark tosses a coin 25 times. What is the probability that it lands on heads exactly seven times?
mezya [45]

Answer:

1.43%

Step-by-step explanation:

we have that we can solve it by means of binomial, in this case m = 25. Also the probability of head is 50%. we need to know when it falls 7 times, therefore x = 7

the formula is:

P (x) = mCx * p ^ x * q ^ (m-x)

we know that p is 0.5 therefore q is equal to 0.5, replacing:

P (7) = 25C7 * 0.5 ^ 7 * 0.5 ^ (25-7)

P (7) = 25! / (7! * (25-7)!) * 0.5 ^ 7 * 0.5 ^ (25-7)

P = 0.0143

that is, the probability is 1.43%
