Answer:

12

Step-by-step explanation:

Given, x and y are inversely proportional.

So, the equation is xy=k, where k is the constant of proportionality

x=4, y=9. plug in the values to find k.

k=4*9 = 36

When x=3, y = k/x =36/3 = 12

y=12, when x=3

Answer:

The 1st baseman can't catch the ball without jumping.

Step-by-step explanation:

To know if the 1st baseman can catch the ball without jumping we need to find the height reached by the baseball by solving the following equation:

[tex] f(x) = -0.004x^{2} + 0.3x + 6 [/tex]

We know that x (the horizontal distance) = 60 feet, so we have:

[tex] f(60) = -0.004(60)^{2} + 0.3(60) + 6 [/tex]

[tex]f(60) = 9.6 ft[/tex]

Since the 1st baseman can reach 8 ft high and the height reached by the baseball is 9.6 ft, the 1st baseman can't catch the ball without jumping.

Therefore, the 1st baseman can't catch the ball without jumping.

I hope it helps you!

There are eight items in that list above.

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

Explanation:

We'll use the AC method of factoring.

The first term has coefficient 3. The last term is -8. Multiply them to get 3*(-8) = -24.

Now let's list all the ways to multiply two integers to get -24

For each pair of factors listed, we'll add up those pairs. Each sum we get represents a possible value of k

Note the symmetry. For instance we have 10 as one sum and -10 as another sum.

-------------------------------

Let's go over an example. Let's say that k = 10

The expression 3x^2+kx-8 turns into 3x^2+10x-8

From the list above, we see that -2+12 = 10. So the two values -2 and 12 will help us factor.

Break up the 10x into -2x+12x and then factor by grouping like so

3x^2 + 10x - 8

3x^2 - 2x + 12x - 8

(3x^2 - 2x) + (12x - 8)

x(3x-2) + (12x - 8)

x(3x-2) + 4(3x - 2)

(x+4)(3x-2)

Therefore, 3x^2 + 10x - 8 factors into (x+4)(3x-2)

We can use the FOIL rule, distribution, or the box method to confirm this.

I'll let you try out other values of k to see how 3x^2+kx-8 factors.

-4x = -40

x = 10

Answer: 7.5%

Step-by-step explanation:

Given: Principal amount = $15,000

Time =- 2 years

Final Amount (Principal + interest)= $17,250

Interest = Final Amount - Principal amount

= $ ( 17250 - 15000  )

= $ 2250

Formula for interest : principal x rate x time

[tex]2250=15000\times rate \times 2\\\\\Rightarrow\ rate =\dfrac{2250}{15000\times2}\\\\\Rightarrow\ rate =0.075\\\\\Rightarrow\ rate =0.075\times100\%=7.5\%[/tex]

Hence, the simplest interest rate on lukes loan =7.5%

Answer:

Unitary cost= $15

Step-by-step explanation:

First, we need to calculate the total cost of the baseball caps:

Total cost baseball caps= 90 - 45

Total cost baseball caps= $45

Now, the unitary cost of each baseball caps:

Unitary cost= total cost / number of units

Unitary cost= 45/3

Unitary cost= $15

Answer:

16 °C

Step-by-step explanation:

We are told that Ken predicts that, in August, the average low temperature will be 20°C, and that the temperature will drop by 4°C in September.

Now, in a standard 12 month calendar, the month of August comes before the month of September.

Thus, in September a drop off by 4°C from 20°C means that the new temperature in September is; 20°C - 4°C = 16 °C

Answer:

16

Answer:

what do you mean the mode

(2 s) + ((−4) s) =

-2 seconds

Sum of the numerator and denominator = 18

If the denominator is increased by 2 , the fraction reduces to 1/3.

the fraction

Let the fraction be x/y.

⟹ x + y = 18

⟹ x = 18 - y -- equation (1)

And,

If the denominator is increased by 2 , the fraction reduces to 1/3.

⟹ x/y + 2 = 1/3

⟹ 3x = y + 2

Substitute the value of x from equation (1).

⟹ 3(18 - y) = y + 2

⟹ 54 - 3y = y + 2

⟹ 54 - 2 = y + 3y

⟹ 52 = 4y

⟹ 52/4 = y

⟹ 13 = y

Substitute the value of y in equation (1).

⟹ x = 18 - 13

⟹ x = 5

Therefore, the required fraction x/y is 5/13.

I hope it will help you.

Answer:

Length is twice the breadth.

→ Length = 2 * x = 2x m.

Also,

Perimeter of the field = 150 m.

We know that,

Perimeter of a rectangle = 2(length + breadth).

Hence,

→ 150 = 2(x + 2x)

→ 150 = 2 * 3x

→ x = 150/2 * 3

→ x = 25

Step-by-step explanation:

Answer:

write answer is 600,, 100% sure

Lol , so this question is from your school google forms? ; )

Answer is 600. Lemme show you how.

Y is proportional to x.

y ∝ x

to remove proportionality , we put k.

y = kx

Now , insert values of y and x to find k.

60 = k *75

k = 75 / 60

Now when Y = 480 , x =?

x = (75/60)(480) = 600.

X = 600

Complete Question

The complete question is shown on the first  and  second uploaded image

Answer:

The estimate of the average stopping distance of all model A tires with a 94% confidence interval is  

       [tex]132.94 <  \mu < 144.86[/tex]

Step-by-step explanation:

From the question we see that

   The sample size is  n  = 8

   The population standard deviation is  [tex]\sigma = 6.7[/tex]

Generally the sample mean is mathematically represented as

        [tex]\= x = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x = \frac{ 145 + 152 + \cdots + 133}{8}[/tex]

=>     [tex]\= x = 138.9[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 94 ) \%[/tex]

=>   [tex]\alpha = 0.04[/tex]

Generally the degree of freedom is mathematically represented as

      [tex]df = n - 1[/tex]

=>   [tex]df = 8 - 1[/tex]

=>   [tex]df = 7[/tex]

Because the n < 30  we will making use of the t table

Generally from the t distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] at a  degree of freedom of [tex]df = 7[/tex]  is  

   [tex]t_{\frac{\alpha }{2}, 7 } = 2.517 [/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = t_{\frac{\alpha }{2} , df} *  \frac{\sigma }{\sqrt{n} }[/tex]

=>    [tex]E = 2.517 *  \frac{6.7 }{\sqrt{8} }[/tex]

=>     [tex]E =5.96 [/tex]

Generally 94% confidence interval is mathematically represented as  

          [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>        [tex]138.9  -5.96 <  \mu < 138.9  + 5.96[/tex]

=>        [tex]132.94 <  \mu < 144.86[/tex]
