The graph shows the solution of a system of equations.how many solutions does it have
slavikrds [6]

Answer:

1

General Formulas and Concepts:

<u>Algebra I</u>

  • Solving systems of equations by graphing

Step-by-step explanation:

We will have 1 solution set when the lines cross once.

We will have no solutions when the lines are parallel.

We will have infinite solutions when the lines are the same.

According to the graph, we see that our lines only intersect once at 1 point. Therefore, there will be only 1 solution.

Paralell has same slope
slope of ax+by=c is -a/b
so a paralalell line to ax+by=c is ax+by=z where a=a and b=b and z is a constant

so
paralalel to 3x-2y=-6 is 3x-2y=?
find ?
given point (4,2)
sub
3(4)-2(2)=12-4=8

equation is 3x-2y=8
solving for slope itnercept or y
minus 3x both sides
-2y=-3x+8
divide by -2
y=3/2x-4

Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .10 significa
nata0808 [166]

Answer:

 The  test statistics is t  =   -1.40

  The critical value is  Z_{\alpha }   = 2.33

   The null hypothesis is rejected

Step-by-step explanation:

From the question we are told that

   The sample size  for men is  n_1 =  80

    The sample  proportion of men that own a cat is  \r p _M  =  0.40

     The  sample  size for  women is n_2  =  80

     The sample  proportion of women that own a cat is  \r p_F  =  0.51

     The level of significance is  \alpha  =  0.10

   The  null hypothesis is  H_o  :  \r p _M   =  \ r P_F

    The alternative hypothesis is  H_a  :  \r p _M  <  \r p_F

Generally the test statistic is mathematically represented as

        t  =    \frac{(\r p_M - \r p_F)}{\sqrt{\frac{(p_M*(1-p_M)}{n_1 } }  +  \frac{p_F*(1-pF)}{n_2 } }

=>  t  =    \frac{(0.40  - 0.51)}{\sqrt{\frac{(0.40 *(1-0.41)}{80} }  +  \frac{0.51*(1-0.51)}{80 } }

=>   t  =   -1.40

The critical value of  \alpha  from the normal distribution table is

     Z_{\alpha }   = 2.33

The p-value  is obtained from the z-table ,the value is  

    p-value =  P( Z < -1.40) =   0.080757

=>    p-value = 0.080757

Given that the p-value  <  \alpha then we reject the null hypothesis

Find the missing side length of a triangle with legs that are 6 feet and 8 feet long.
Vikentia [17]

Answer:

10 feet.

Step-by-step explanation:

I am assuming this is a right triangle. We use Pythagoras theorem:

h^2 = 6^2 + 8^2

h^2 = 100

h = 10 feet.
