Answer:

D. a combination of operations on letters and numbers.

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

1/3 yard lengths times 3 equals 3 (or 1 yard).

There are 3 numbers of  1/3 yard lengths are in 1 yard.

A summation, which is the result of adding two or more numbers or quantities, is also known as a sum.

A mathematical operation known as subtraction involves two values that will be subtracted to produce a new value.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.

Division is divide of any two numbers so it will give a new divided value for example 4/2 will gives us 2.

1 yard = 1/3 yard +  1/3 yard +  1/3 yard

The lowest common multiple of the right hand will be 3

So,

1 yard = (1 + 1 + 1)/3 yard

1 yard = 3/3 yards

1 yard = 1 yard

Hence in 1 yard, there is a total of 3 numbers of 1/3 yards.

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:

If the ratio of one variable to the other is constant, then the two variables have a proportional relationship, If x and y have a proportional relationship, the constant of proportionality is the ratio of y to x.

Step-by-step explanation:

Answer:

The answer is D

Step-by-step explanation:

I would give an explanation but it would take to long. The original answer is 21, there is no other equation that equals 21.

4²= 16

Work - 4 x 4 = 16

Work - 2 x 2 x 2 x 2 = 16

Work - 8 x 8 = 64

Work - 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2= 256

Answer:

peter = $54

jane = $36

Step-by-step explanation:

let peter = x

let jane = y

peter + jane = $90

x+y = 90 --------- (1)

peter gave jane $16 = x-16

jane gets extra $16 from peter = y+16

peter would have $14 less than jane

jane - peter = $14

(y+16)-(x-16) = 14

y+16-x+16 = 14

y-x+32 = 14

y-x = 14-32

y-x = -18 ---------- (2)

x+y = 90 --------- (1)

y-x = -18 --------- (2)

from (1)

x+y = 90

y = 90-x --------- (3)

substitute (3) into (2)

y-x = -18

90-x-x = -18

90-2x = -18

-2x = -18-90

-2x = -108

x = 54

substitute x = 54 into (3)

y = 90-x

y = 90-54

y = 36

x = peter = $54

y = jane = $36

Answer:

210 cm²

Step-by-step explanation:

Area of the surface having dimensions 6 cm × 11 cm

[tex]A_1[/tex] = 11 × 6 = 66 cm²

Area of the surface having dimensions 3 cm × 6 cm

[tex]A_2[/tex] = 3 × 6 = 18 cm²

Area of the surface having dimensions 7 cm × 6 cm

[tex]A_3[/tex] = 7 × 6 = 42 cm²

Area of the surface having dimensions 5 cm × 6 cm

[tex]A_4[/tex] = 5 × 6 = 30 cm²

Area of the trapezoidal surface on the top = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

[tex]A_5[/tex] = [tex]\frac{1}{2}(11+7)3[/tex]

    = 27 cm²

Area of the trapezoidal base [tex]A_6[/tex] = Area of the surface on the top = 27 cm²

Total surface area = [tex]A_1+A_2+A_3+A_4+A_5+A_6=66+18+42+30+27 + 27[/tex]

                                               = 210 cm²

Therefore, total surface area of the trapezoidal prism = 210 cm²

Answer:

x = 8

Step-by-step explanation:

2x + 5 = 21

      -5    -5

      2x = 16

     2x/2 = 16/2 ( divided 2 on both sides)

     you get x= 8

to check your work, replace x with 8 in the equation

                            2 x 8 + 5 = 21    ( don't forget PEMDAS!!)

                               16 + 5 = 21

Step-by-step explanation:

Answer:

816 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.

✔️Surface area of the larger rectangular prism:

Area = L*W*H = 20*5*6 = 600 cm²

✔️surface area of the smaller rectangular prism:

Area = L*W*H = 12*4*6 = 288 cm²

✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.

Area = L*W = 12*6 = 72 cm²

Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².

Answer:

c

Step-by-step explanation:

it would have some exponent but its the only one that is constant

Step-by-step explanation:

The last step is a little wrong. Lemme show you:

x(x + 2) + (x + 2)

Imagine there is an invisible '1' infront of (x + 2) like this:

= x(x + 2) + 1(x + 2)

Now we can combine the like terms together:

= (x + 1)(x + 2)

This is the correct factorization.

Answer:

3/4 of a 6-ounce glass

Step-by-step explanation:

Given time = 2/3 of hour

As hour = 60 min

= 120/3

= 40 mins

So,

40 mins: water in take is 3 ounce

1 minute: water in take is 3/40

60 mins: water in take is (3/40) x 60 = 4.5 ounce

Answer:

Their quotients are a constant

Step-by-step explanation:

Required

Quotient of two variable

Let the variables be x and y

The quotient of x and y in this case is their constant of variation.

Take for instance:

[tex](x_1,y_1) = (2,4)[/tex]

[tex](x_2,y_2) = (4,8)[/tex]

[tex](x_3,y_3) = (8,16)[/tex]

Their quotient is calculated as follows:

[tex]Quotient = \frac{y}{x}[/tex]

[tex](x_1,y_1) = (2,4)[/tex]

[tex]Quotient = \frac{4}{2} = 2[/tex]

[tex](x_2,y_2) = (4,8)[/tex]

[tex]Quotient = \frac{8}{4} = 2[/tex]

[tex](x_3,y_3) = (8,16)[/tex]

[tex]Quotient = \frac{16}{8} = 2[/tex]

Notice that the quotient has a constant value of 2.

However, the sum, difference or products will give a different set of values entirely.

Hence, option (d) is correct

Answer:

2

Step-by-step explanation:

4y = 2x + 8

First get the equation in slope intercept form  y= mx+b where m is the slope and b is the y intercept

Divide each side by 4

4y/4 = 2x/4 +8/4

y = 1/2x +2

The slope is 1/2 and the y intercept is 2

Answer:

2

Step-by-step explanation:

Manipulate your equation into slope-intercept form: y = mx + b, where b is the y-intercept.

To do this, divide 4 from both sides:

[tex]y=\frac{1}{2} x+2[/tex]

b = 2
