What is the y-intercept of y= -3x

BigorU [14]

Answer:

c

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and

b is the y-intercept.

y=mx+b

m=−3

b=0

y=-3x+0

Consider the system of components connected as in the accompanying picture. Components 1 and 2 are connected in parallel, so tha

bagirrra123 [75]

Answer:

P(system) = p(subcomp1 ∩ subcomp2)

P(system) = 1.60 x 0.64

P(system) = 1.0240

Step-by-step explanation:

In the system we have 2 subsystem

Let say subsystem 1 and subsystem 2

Subsystem 1 consist of 2 components, component 1 and component 2 that subsystem 1 works if and only if either component 1 or component 2 work

I.e p(subcomp1) = p ( comp1 | comp2)

Since the P(component works) = 0.80

Therefore P(subcomp1) = p(comp1) + p(comp2)

= 0.80 + 0.80

P(subcomp1) = 1.60

Subsystem 2 consist of 2 components, component 3 and component 4 that subsystem 2 works if and only if both component 3 and component 4 work

I.e p(subcomp2) = p ( comp3 ∩ comp4)

Since the P(component works) = 0.80

Therefore P(subcomp2) = p(comp3) x p(comp4)

= 0.80 x 0.80

P(subcomp2) = 0.64

Therefore since the component are independent of one another

P(system) = p(subcomp1 ∩ subcomp2)

P(system) = 1.60 x 0.64

P(system) = 1.0240

box contains 5 blue balls and 5 red balls. Randomly pick 3 balls with replacement and record the color (Pick one first and put i

olchik [2.2K]

Answer:

1/8

Step-by-step explanation:

Total number of balls is 5 red balls + 5 blue balls = 10 balls

Now probability of picking a blue ball is equal to the probability of picking a red ball. This is because we have equal number of blue balls as red balls.

P(B) = 5/10 = 1/2 = P(R)

Now probability of picking 2 red balls and 1 blue ball with replacement will be :

1/2 * 1/2 * 1/2 = 1/8

A recent report shows that 62% of people are interested in black holes. If this number is down from the previous year by 8%, wha

Likurg_2 [28]

Answer: The percent of people who were interested in black holes last year was 70%.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

People interested in black holes this year: 62%

If the number is down from the previous year by 8%, to calculate the percent of people who were interested last year we simply have to add the 8% loss to the actual 62 %.

So, mathematically speaking:

62%+8%=70%

In conclusion, the percent of people who were interested in black holes last year was 70%.

Feel free to ask for more if it´s necessary or if you did not understand something.
