Answer:

The answer is 1,328

Step-by-step explanation:

The number of ounces that she weighs will be 1328 ounces. Then the correct option is D.

Conversion means converting the same thing into different units.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

If a child weighs 83 pounds. We know that in one pound, there are 16 ounces.

Then the number of ounces that she weighs will be

⇒ 83 x 16

⇒ 1328 ounces

Then the number of ounces that she weighs will be 1328 ounces. Then the correct option is D.

Answer:

Claim : men weigh of wild jackalopes is 69.9

The null hypothesis : H0 : μ = 69.9

Alternative hypothesis : H1 : μ ≠ 69.9

Test statistic = −2.447085

P value = 0.0174

Conclusion :

Fail to Reject the Null hypothesis

Step-by-step explanation:

From the question given :

The claim is that : mean weight of wild jackalopes is still the same as 10 years with a mean weight of 69.9 lbs.

The null hypothesis : H0 : μ = 69.9

Alternative hypothesis : H1 : μ ≠ 69.9

Using calculator :

Sample mean (x) = 66

Sample standard deviation (s) = 12.345

The test statistic t :

(x - μ) / (s/√n)

n = sample size = 60

(66 - 69.9) / (12.345 / √60)

t = −2.447085

P value at α 0.01, df = 59 is 0.0174

Since the p value is > 0.01, the result is not significant at 0.01. Therefore, we fail to reject the Null

Answer:

[tex]Fraction = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Pie = \frac{3}{4}[/tex]

[tex]Workers = 3[/tex]

Required

Determine the fraction received by each worker

To do this, we simply divide the fraction of the pie by the number of workers.

[tex]Fraction = \frac{Pie}{Workers}[/tex]

[tex]Fraction = \frac{3}{4}/3[/tex]

Convert to multiplication

[tex]Fraction = \frac{3}{4} * \frac{1}{3}[/tex]

[tex]Fraction = \frac{3}{12}[/tex]

Divide numerator and denominator by 3

[tex]Fraction = \frac{3/3}{12/3}[/tex]

[tex]Fraction = \frac{1}{4}[/tex]

The distance cover by Noah in 1 hour to cover distance is 6.5 miles

Step-by-step explanation:

Given as :

The distance cover by Lin = 2 miles = miles

The time taken to cover distance by Lin = hours

Again

The distance cover by Noah = 8 miles = miles

The time taken to cover distance by Noah = hours

Let the distance cover by Noah in 1 hour = d miles

∵ The distance cover by Noah in hours = miles

∴ The distance cover by Noah in 1 hour =

I.e d = miles

or, d = = 6.5 miles

So, The distance cover by Noah in 1 hour = d = 6.5 miles

Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer

Answer: 1 inch

Step-by-step explanation: when you round to the tenth place, you look at the number to the right of the decimal. Because it is .95, you round up. If it was .94 or under, you would round down. .95 rounded up would make 10 in the tenths place, so we add our decimal to get 1.0, or 1 inch

Answer:

Calculate Percentage Decrease:

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.

Step-by-step explanation:

The percentage change is equivalent to a 8% decrease followed by a 15% decrease is 78.2%.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

We have to find percentage change is equivalent to a 8% decrease followed by a 15% decrease.

So, (1- 8%)(1- 15%)

= (1- 8/100)(1-15/100)

= (1-0.8)(1-0.15)

= 0.92 x 0.85

= 0.782

Now, converting to percentage

= 0.782 x 100/100

= 78.2 /100

= 78.2%

Step-by-step explanation:

Answer:

x = 1.75 -y, y = 1.25 + x

Step-by-step explanation:

Part One

2x + y = 3.5

Divide

x + y = 1.75

Move the variable and change its sign

x = 1.75 -y

Part Two

-x + 2y = 2.5

Divide

-x + y = 1.25

Add

y = 1.25 + x

Answer:

Slope of 2

Step-by-step explanation:

First thing is to look at the change in x and y from the points. You can do this by subtracting the x valie from the other value and the same for the y values. So you would do 2-0=2.

So we know the change in x between the points, so now we find the change in y. 5-1=4.

Now that we know the change in x and y, we use the expression below to solve for the slope.

[tex] \frac{rise}{run} \: or \: \frac{y}{x} [/tex]

We can insert what we found and then solve for the equation

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

So we solve for that, which is 2. Now we know the slope is 2.

Answer:

given us,

(x1y1)= (2,5)

(x2y2)= (0,1)

here,

(y-y1)= (y2-y1)/ (x2-x1)× (x-x1)

or, (y-5)=(1-5)/(0-2)× (x-2)

or, y-5= -4/-2 ×(x-2)

or,y-5= 2(x-2)

or, y-5/ x-2= 2

or,y-5= 2x-4

or, 2x-y= -4+5

:. 2x-y= 1

Step-by-step explanation:

2x-y= 1
