function or not a function​

Answer:

D. 1/2

Step-by-step explanation:

1/2 = 0.5

1/2 it´s a representation of a decimal number.

Answer: Choice D)

No slope, the term x2-x1 is zero and we cannot have zero in the denominator.

=========================================

Explanation:

The two points both have x coordinates x = 7. Since both x coordinates are the same, they subtract to 0. Recall that something like 1/0 is undefined, so we cannot have 0 in the denominator.

The line through (7,10) and (7,20) is a vertical line. All vertical lines have undefined slopes.

Answer:

no its false its equal

-4 isnt greater or > than -4 it's the exact same

Answer:

125%

Step-by-step explanation:

x --> 9/4 x.

x and x cancels out so we have to find out what percent 9/4 is. 9/4= 2 1/4 = 225%.

since we first started from 100%, 225%-100%=125% Hope this helped :)

Answer:

[tex] 3 - a [/tex]

Step-by-step explanation:

Given that when you add two numbers together the result is 3.

The greater of the number is given as a.

Let "x" represent that lesser number.

Thus:

[tex] a + x = 3 [/tex]

To make x the subject of the formula. Subtract a from both x.

[tex] a + x - a = 3 - a [/tex]

[tex] x = 3 - a [/tex]

Therefore, the expression that represents the lesser number, x, is:

[tex] 3 - a [/tex]

Answer:

d. Both I and II are false

Step-by-step explanation:

When there is a high degree of linear correlation between the predictors the errors are found.

The basic objective of the regression model is to separate the dependent and independent variables. So if the variables have high degree of linear correlation then the multi collinearity causes problems or has errors. It is not necessary that multi collinearity must be present with high degree of linear correlation.

For example we have 3 variable of heat length and time. And all of them have a high degree of correlation. With increase in heat and time the length increases . But for multi collinearity with the increase of time and decrease of heat length does not increase. So this causes errors.

y-hat = 135 + 6x + errors

The linear relationship between height and weight is inexact. The deterministic relation in such cases is then modified to allow the inexact relationship between variables and a non deterministic or probabilistic model is obtained which has  error which are unknown random errors.

y- hat= a + bXi + ei   (i=1,2,3...)

ei are the unknown random errors.

So both statements are false.

Answer:

The q value coefficient is 5

Step-by-step explanation:

The q value are all positive and negative factors of the first coefficient (5)

The p value are all positive and negative factors  of the last coefficient (2)

Answer:

9

Step-by-step explanation:

I think 9 since there’s a right angle, so there’s an assumed right angle on the other side of the line. 9 is the hypotenuse when AB is 3 so I think CD would also be 9 since BC is 3 as well.

Answer:

The answer would be (D 70 degrees

Step-by-step explanation:

Each triangle is 180 degrees. 180 - 40 equals 140. 140 divided by two equals 70.

Hope this helps ^^✨

Answer:

D: 70°

Step-by-step explanation:

Angles A and B are going to be the same, and the interior angles of a triangle must equal 180°, so D is the correct answer

70 + 70 + 40 = 180

Answer:

Santana scored 12 2-point baskets.

Step-by-step explanation:

Given that Santana converted 22 baskets in his last basketball game, totaling 54 points at the end of the game, and that in basketball the baskets are worth 2 and 3 points, to determine the number of baskets of each value that Santana converted, the following logic reasoning must be done:

If all the baskets were 2 points, the total of points made would have been 44 (22 x 2). Now, there are 10 more points, which are attributable to the 3-point baskets (that is, each extra point is a 3-point basket). Therefore, since 54 minus 44 equals 10, Santana made 10 3-point baskets and 12 2-point baskets.

This is verified through the following calculation:

(10 x 3) + (12 x 2) = X

30 + 24 = X

54 = X

Answer:

 The decision rule is  

Fail to reject the null hypothesis

  The conclusion is  

There no sufficient evidence to show that the proportion of salmonella in the region’s water differs from the proportion of salmonella in the region’s wildlife

Step-by-step explanation:

From the question we are told that

   The first  sample size is [tex]n_1 = 252[/tex]

    The number that tested positive is  [tex]k_1 = 18[/tex]

     The second sample size is  [tex]n_2 = 476[/tex]

     The number that  tested positive is  [tex]k_2 = 20[/tex]

     The level of significance is  [tex]\alpha = 0.01[/tex]

Generally the first sample proportion is mathematically represented as

      [tex]\^ p _1 = \frac{k_1 }{ n_1 }[/tex]

=>    [tex]\^ p _1 = \frac{18 }{ 252 }[/tex]

=>    [tex]\^ p _1 = 0.071[/tex]

Generally the second sample proportion is mathematically represented as

      [tex]\^ p _2 = \frac{k_2 }{ n_2 }[/tex]

=>    [tex]\^ p _2 = \frac{20 }{ 476}[/tex]

=>    [tex]\^ p _2 = 0.042[/tex]

The  null hypothesis is            [tex]H_o : p_1 - p_2 = 0[/tex]

The alternative hypothesis is  [tex]H_a : p_1 - p_2 \ne 0[/tex]

Generally the test statistics is mathematically represented

       [tex]z = \frac{ \^ p_1 - \^ p_2 - ( p_ 1 - p_2 )}{ \sqrt{\frac{\^ p_1 (1-\^ p_1)}{ n_1 } + \frac{\^ p_2 (1-\^ p_2)}{ n_2 } } }[/tex]

=>    [tex]z = \frac{ 0.071 - 0.042 - 0 }{ \sqrt{\frac{0.071 (1-0.071)}{ 252 } + \frac{0.042 (1-\^ 0.042)}{ 476 } } }[/tex]

=>    [tex]z = 1.56[/tex]

From the z table  the area under the normal curve to the right corresponding to  1.56   is  

        [tex]P(Z > 1.56 ) =0.05938[/tex]

Generally the p-value is mathematically represented as

         [tex]p-value = 2 * P(Z > 1.56 )[/tex]

=>      [tex]p-value = 2 * 0.05938[/tex]

=>      [tex]p-value = 0.1188[/tex]

From the value obtained we see that   [tex]p-value > \alpha[/tex] hence

  The decision rule is  

Fail to reject the null hypothesis

  The conclusion is  

There no sufficient evidence to show that the proportion of salmonella in the region’s water differs from the proportion of salmonella in the region’s wildlife

Answer:

  x=16

Step-by-step explanation:

Answer: -3 + 4*x^2 = - 3 + (2*x)^2

Any value of x is a solution for this eqution.

Step-by-step explanation:

She ended with -3 = -3

This is trivial, if we had an equation with one variable, something like:

f(x) = equation.

Ending with something like -3 = -3 means that we do not have any restriction with respect to x, so x could take any value.

This will happen if the terms with x in the left side are exactly the same as the terms in the right side, for exampe:

-3 + 4*x^2 = -3 + 4*x^2

In that case, we can substrrat 4*x^2 in both sides, and we will end with:

-3 = -3

This means that the solution for this equation is any value of x.

We also could rewrite this as:

-3 + 4*x^2 = - 3 + (2*x)^2

So the terms look different, but the terms are exactly the same for any value of x.

Answer:

25% off

Step-by-step explanation:

$32 is 100%. 8 dollars was taken away, and since 8 is 1/4 of 32, we can divide 100% by 4 to get 25%. 25% is $8

Answer:

25%

Step-by-step explanation:

24/32=0.75

100-0.75= 0.25

So 25% off.

Answer:

529

Step-by-step explanation:

892-363=529

529+363=892

Final Answer: [tex]529[/tex]

Steps/Reasons/Explanation:

We will write down the equation [tex]892 = x + 363[/tex] because we would need to get [tex]x[/tex] by itself. Doing this will make us able to find the other number.

Question: The sum of 2 numbers is 892. One of the numbers is 363. What is the other number?

Step 1: Subtract [tex]363[/tex] from both sides.

[tex]892 - 363 = x[/tex]

Step 2: Simplify [tex]892 - 363[/tex] to [tex]529[/tex].

[tex]529 = x[/tex]

Step 3: Switch sides.

[tex]x = 529[/tex]

Answer:

Local Grocer store's offer is the better deal

Step-by-step explanation:

In order to calculate which is the better bargain, we need to find out how much each deal is charging for the individual can of tuna. We calculate this by dividing the total of the offer by the number of cans of tuna it includes like so...

Local: $3.28 / 4 = $0.82 per can

Ocean's Best: $1.88 / 2 = $0.94 per can

Therefore, we can see that the Local Grocer store's offer is the better deal since it is selling you each can at 0.82 cents compared to the 0.94 cents that Ocean's Best is charging per can.

Answer:

It's seastar

Step-by-step explanation: tbh I put in seastar as an answer on ixl and got it correct but if you want to know what you have to all you need to do is divide price by amount and the one with less is the better option for example if you have a 4 pack for $4.56 you would do $4.56/4 price always goes first remember that! :D
