Answer:

y = -1/2x+4

Step-by-step explanation:

y = 2x-1

This equation is in slope intercept form  y = mx+b  where m is the slope

m=2

A line perpendicular will have a slope that is the negative reciprocal

m = -1/2

Using the slope intercept form

y = mx+b

y = -1/2x+b

and the point given (2,3)

3 = -1/2(2)+b

3 = -1+b

4 =b

y = -1/2x+4  is the equation of a line that is perpendicular to the original line and contains (2,3)

John’s father is 5 times older than John and John is twice as old as his sister Alice. In two years time, the sum of their ages
oksano4ka [1.4K]

Answer:

John’s age is 8 years

Step-by-step explanation:

Let

x -----> John’s father's age

y -----> John’s age

z -----> John’s sister's age

we know that

x=5y -----> equation A

y=2z

z=y/2 -----> equation B

(x+2)+(y+2)+(z+2)=58

x+y+z+6=58

x+y+z=52  -----> equation C

Substitute equation A and equation B in equation C and solve for y

5y+y+y/2=52

Multiply by 2 both sides to remove the fraction

10y+2y+y=104

13y=104

y=8

<em>Find the value of x</em>

x=5(8)=40

<em>Find the value of z</em>

z=8/2=4

therefore

John’s father's age is 40 years

John’s age is 8 years

John’s sister's age is 4 years

12/-4 =<br> pls help i don’t understand
Sveta_85 [38]

\text {Hello! Let's Solve this equation!}

\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}

\text {Here are some tips on dividing/multiplying equations like this.}

\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}

\text {Now Divide!}

\text {12/-4=}

\fbox {-3}

\text {As you can see 4 is a negative number so our result came out as a negative number.}

\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}

\text {-3*-4=12}

\text {Best of Luck!}

\text {-LimitedX}

During the first 13 weeks of the television season, the Saturday evening 8:00 p.m. to 9:00 p.m. audience proportions were record
SpyIntel [72]

Part 1: Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)

Part 2:

H0:  

Ha:  

Part 3: The test statistic is given as 3.0081.

Part 4: The p-value is given as  0.39037

Step-by-step explanation:

As per the data

Part 2

H0:  

Ha:  

Part 3

As per the sample is of 300 homes, the expected values are given as

ABC=p(ABC)*300=0.30*300=90

CBS=p(CBS)*300=0.27*300=81

NBC=p(NBC)*300=0.26*300=78

IND=p(IND)*300=0.17*300=51

Now the values actually are given as

ABC=94

CBS=71

NBC=88

IND=47

So the test static is given as

So the test statistic is given as 3.0081.

Part 4

Now the degree of freedoms are given as 4-1=3

and chi square  is given as 3.0081 so for α = 0.05 , the p-value is given as  0.39037

Part 1.

As the value of p in part 4 is greater than the value of α = 0.05, thus Do not reject H0. There has not been a significant change in the viewing audience proportions.(The above conclusion holds as the p-value is greater than the significance level of 0.05)

Two students from a group of eight boys and 12 girls are sent to represent the school in a parade.
Deffense [45]

<u>Answer</u>

c. 62/95


<u>Explanation</u>

Probability is the chance of an event happening.

Probability = (favorable outcome)/(total outcome)

P(girl) = 12/20 × 11/19

        = (12×11)/(20×19)

         = 132/380

         = 33/95

P( not a girl) = 1 - 33/95

                     = 62/95
