Hypothesis

a. If two integers are even

Conclusion

b. then their sum is even

Step-by-step explanation:

We divide the statement into two parts . The first part is true only when the second is also true. The only way we can reject the hypothesis is that the conclusion is false.

In the statement "If two integers are even, then their sum is even" the part "If two integers are even" would be considered true or false on the basis of "then their sum is even" validity. So if the "then their sum is even" (conclusion )  Part is proved then the "If two integers are even" ( hypothesis) is also true.

Hence the hypothesis is

a. If two integers are even

and

Conclusion is

b. then their sum is even

Answer:

48000

Step-by-step explanation:

6÷2= 3 in.

3×100= 300 in.

3.2÷2=1.6 in.

1.6×100= 160 in.

A= 160×300= 4800 in.

The required area of the section marked by Dr. Gordon is 48,000 feet².

Given that
Dr. Gordon has a scale drawing of a building site.
The drawing uses the scale 2 in. on the drawing for every 100 ft on the building site.
Dr. Gordon marks a 6 in. -by-3.2 in.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,

Dr. Gordon marks a 6 in. -by-3.2 in
Length = 6 in
Length= 300 ft (since 2 in = 100 ft)

Width = 3.2 in
Width  = 160 ft

Now the required area of the section is = length x width
                                                                  = 300 * 160
                                                                   = 48000 feet²

Thus,  the required area of the section marked by Dr. Gordon is 48,000 feet².

Its all about the Zeros

Answer:

Y=8

Step-by-step explanation:

If it's a line that is parallel to the x-axis, and you know the equation of a line is y=mx+b, the slope(m) is 0 because the line is not a positive or negative slope (since it's parallel to the x-axis).

So, we now have y=b, where b is the y-intercept. Now, since we know one of its coordinates are (5,8), we know that this line will always stay on y=8 since 8 is the y coordinate of (5,8)

An easy shortcut is if you see the question say parallel to the x-axis, the equation of the line will be y=___; if it says the line is parallel to the y-axis, the equation will be x=___

Step-by-step explanation:

We are given 4 points.

[tex](\frac{1}{2},2)[/tex]

[tex](\frac{5}{8},\frac{5}{2})[/tex]

[tex](\frac{3}{4},3)[/tex]

[tex](\frac{7}{8},\frac{7}{2})[/tex]

Using this, we can make an equation.

[tex]y=4x[/tex]

I got [tex]m=4[/tex] by using the slope formula.

[tex]m=\frac{2.5-2}{0.625-0.5}[/tex]

[tex]m=\frac{0.5}{0.125}[/tex]

[tex]m=4[/tex]

So the equation we have is [tex]y=4x[/tex]

Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for [tex]y[/tex], which is the number of cracker packages.

[tex]25=4x[/tex]

[tex]x=\frac{25}{4}[/tex]

We need to use [tex]\frac{25}{4}[/tex] teaspoons of peanut butter to make 25 packages of crackers.

Answer:

C.) 37%

Explanation:

To find this out, turn 3/8 into decimal form, (0.375).

Now, turn each percent into standard form. (Also decimal form)

26% = 0.26, 27% = 0.27, 37% = 0.37, and 38% = 0.38.

The decimal closest to 0.375 is 37%.

Hope this helped! ♥♥

Answer:

D.) 38%

Step-by-step explanation:

Convert the fraction into a decimal:

[tex]\frac{3}{8}=0.375[/tex]

Convert the decimal into a percent:

[tex]0.375*100=37.5[/tex]

0.375 = 37.5%

Round the percent:

37.5% ≈ 38%

Option D is the best answer.

Answer:

13 seconds more

Step-by-step explanation:

Answer:

Step-by-step explanation:

A). Number of samples given in the ogive = Number of points given n the graph

    Number of points plotted on the graph = 16

    Therefore, number of samples given = 16

B). Frequency at a point where weight of the pumpkins is 23.5 = 10

    Frequency at a point where weight of the pumpkin is 24.5 = 23

    Increase in frequency = 23 - 10 = 13

   None other points have the increase more than the given points.

Location of the greatest increase in the frequency is between the weights 23.5 - 24.5 pounds.

The number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.

We are provided with an ogive curve. In the x-axis, we have weight in pounds and y-axis represents frequency.

(a).

Now, the number of points on the ogive represents the number of sample.

So, the number of points on the curve is 16 which is also the number of samples.

(b).

The greatest increase in frequency is represented in the range 23.5 to 24.5.

The greatest hike in frequency is about 10.

Therefore, the number of samples is 16, and the location of greatest increase in frequency is 23.5 to 24.5.

Answer:

199

Step-by-step explanation:

So we have three consecutive numbers that totals 600 when added.

Let's let the first number be n.

This means that the next number is (n+1), and the subsequent number is (n+2).

This totals 600. In other words:

[tex](n)+(n+1)+(n+2)=600[/tex]

To solve for the integers, solve for n.

Combine like terms:

[tex]3n+3=600[/tex]

Subtract 3 from both sides:

[tex]3n=597[/tex]

Divide both sides by 3:

[tex]n=199[/tex]

So, the first integer is 199.

So our sequence is: 199, 200, 201.

So, the least of the three is 199.

And we're done!

Answer:

199 200 201
