Answer:

-3326

Step-by-step explanation:

replaces the x's with -3

so (5(-3))^3 + (2(-3))^2 -4(-3)+1 = -3326

Answer:

35 and 32

Step-by-step explanation:

35 and 32

because when we add 35 and 32 then their sum is 67

when we subtract 35 and 32 then their difference is 3

I hope u understand it

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: -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:

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:

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: 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:

 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: 2:45 pm

Step-by-step explanation:

Find the length of the tour;

90 minutes at Empire State

180 minutes in Central Park

45 minutes in Times Square

= 90 + 180 + 45

= 315 minutes

= 5.25 hours

= 5 hours 15 minutes

Dinner Reservation is at 8.

Latest time they can start is;

= 8 - 5.25 hours

= 2.75

= 2 hours 45 minutes

= 2:45 pm

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:

Formula: [tex]c=\frac{sale\ price\ of\ 7}{7}+\$0.75[/tex]

Normal Price: [tex]\$1.15[/tex]

Step-by-step explanation:

First, you have to find the current price of one cookie.

Since 7 cookies cost $2.80, then the price for one sale price cookie would cost

Then you would have to add the $0.75 to the sale price to get the normal price.

[tex]\$0.4\ +\ \$0.75=\$1.15[/tex]

The normal price of a cookie would be $1.15.

The formula to get that answer would be:

[tex]c=\frac{sale\ price\ of\ 7}{7}+\$0.75[/tex]

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:
