Answer:

Step-by-step explanation:

The answer is C because if you plug in 2 into the 4x, it would be 4(2) which is 4*2. If you do the math the answer is 8. Moving on to the 2y if you plug in 0, into the y spot, it would be 2(0) which is 2*0. if you do the math on this one its 0. Now if you add 8 and 0. You would get the answer 8

Find the x-intercept of the graph of each equation <br>a. 3x+2y=7. <br><br>b. 2x+3y=7

Burka [1]

Hello!

The x intercept is when the y value is 0

Put 0 in for y to get the x-intercepts
------------------------------------------------------------------------------------------------------
Part A

3x + 2y = 7

Put 0 in for y

3x + 2(0) = 7

Simplify

3x = 7

Divide both sides by 3

x = 2.333...

The x-intercept is at the point (2.333, 0)
------------------------------------------------------------------------------------------------------
Part B

2x + 3y = 7

Put 0 in for y

2x + 3(0) = 7

Simplify

2x = 7

Divide both sides by 2

x = 3.5

The x-intercept is at the point (3.5, 0)

Hope this helps!

Pavel [41]

Answer:

a) For this case we can use the binomial model since we assume independent events and the same probability for each trial is the same p =0.15

b) $P(X=0)=(10C0)(0.15)^0 (1-0.15)^{10-0}=0.1969$

c) $P(X=3)=(10C3)(0.15)^3 (1-0.15)^{10-3}=0.1298$

d) $P(X \geq 1)= 1-P(X$

And using the result from part a we got:

$P(X \geq 1)= 1-P(X$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n p)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Solution to the problem

Part a

For this case we can use the binomial model since we assume independent events and the same probability for each trial is the same p =0.15

Part b

For this case we want this probability:

$P(X=0)$

And replacing we got:

$P(X=0)=(10C0)(0.15)^0 (1-0.15)^{10-0}=0.1969$

Part c

For this case we want this probability:

$P(X=3)$

And replacing we got:

$P(X=3)=(10C3)(0.15)^3 (1-0.15)^{10-3}=0.1298$

Part d

For this cae we want thi probability:

$P(X \geq 1)$

And we can use the complment rule and we got:

$P(X \geq 1)= 1-P(X$

And using the result from part a we got:

$P(X \geq 1)= 1-P(X$

ILL MARK YOU BRAINLIEST IF YOU ANSWER CORRECTLY

aev [14]

Answer:

First Question:

0042=4210000=42104=42⋅1104.

Recall that 1ab=a−b and vice versa,

so we can write 42⋅1104=42⋅10−4 .

The correct option is (D)

Second Question:

6120 is your answer

Take the decimal in 6.12 and move it to the right three times. You should get your answer.
