Answer:

Step-by-step explanation:

Given that:

scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7

Since the scores are already in ascending order; then the median which is the middle number will be:

median = (5th term + 6 term)/2

median = (5+5)/2

median = 10/2

meian = 5

b)

Use the cumulative percentage table

X     frequency    cumulative frequency     cumulative percentage

2         1                     1                                            10%

3         1                     2                                           20%

4        2                     4                                            40%

5        3                     7                                             70%

6        2                     9                                             90%

7        1                     10                                             100%

fraction = the no. required to reach 50%/ no. in that interval

= 1/3

Since we have a total of 4 boxes when we reach the value of 4.5

The median of the continuous variable = 4.5 + (1/3)

The median of the continuous variable = 4.833

The median of the continuous variable ≅ 5

Answer:

y=3/4x+1/2

Step-by-step explanation:

slope intercept form: y=mx+b

find the slope with y2-y1/x2-x1: (-4-5)/(-6-6)= 3/4

substitute one of the coordinates in the equation with the slope: 5=3/4(6)+b

solve to find b:

b=1/2

substitute in the equation:

y=3/4x+1/2

Answer:

[tex]A(t)=250-230e^{-\frac{t}{50} }[/tex]

Step-by-step explanation:

A(t) is the amount of salt in the tank at time t.

dA / dt = rate of salt flowing into the tank - rate of salt going out of the tank

dA / dt = (1 g/L)*(5 L/min) - (A(t)/250 g/L) * (5L/min)

dA / dt = 5 g/min - (A(t) / 50) g/min

[tex]\frac{dA}{dt}+\frac{A(t)}{50} = 5\\\\The\ integrating\ factor(IF)= e^{\int\limits \frac{1}{50}dt }=e^{\frac{t}{50} }\\\\Multiplying\ through\ by\ the\ I.F:\\\\\frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} } = 5*e^{\frac{t}{50} }\\\\Integrating \ both \ sides:\\\\\int\limits[ \frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} }] dt=\int\limits 5e^{\frac{t}{50} } dt\\\\A(t)e^{\frac{t}{50} } =\int\limits 5e^{\frac{t}{50} } dt\\\\[/tex]

[tex]A(t)e^{\frac{t}{50} } =250e^{\frac{t}{50} }+C\\\\A(t)=250+Ce^{-\frac{t}{50} }\\\\But\ A(0) = 20\\\\20=250+Ce^{-\frac{0}{50} }\\\\C+250=20\\\\C=-230\\\\A(t)=250-230e^{-\frac{t}{50} }[/tex]

Answer:

R = 0.8815 ;

y = 6.14679X + 2.33028 ;

14.624

Step-by-step explanation:

Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.

The regression line equation obtained by Plotting the values to generate a linear model is :

y = 6.147X + 2.330

With ;

Slope or gradient being 6.147

Intercept = 2.330

C.)

x = 2

y = 6.147X + 2.330

y = 6.147(2) + 2.330

y = 14.624

Answer:

x=25

Step-by-step explanation:

To get this answer you need to simplify everything that you can. So basically, first you would combine 2x and x to get 3x+18. Note that you don't need to use the second part of the equation if you don't want to. Same with the third because they are all equal. Noting this, you subtract 18 from both sides of the equation leaving you with 75= 3x. Proceed to divide both sides by three and end with the answer 25=x.

Answer:

x=27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5/3x-4/3x-1=8

5 /3 x+  −4 /3 x+−1=8

(5 /3 x+  −4 /3 x)+ (−1) =8 (Combine Like Terms)

1/3x-1 =8

1/3x=9

(1/3 x) x 3 = 3 x 9

x=27

Answer: x=27

Step-by-step explanation: if you want to Solve for X, you have to by simplify both sides of the equation, then isolating the variable.

Step-by-step explanation:

4 wrong = 80%

The statement that could be false on the interval is if x is greater than π/2

Given the function g(x)=√ 1−sin2x

We are to get the value of x that will make the function not exist. For the function not to exist, hence:

sin2x> 1

Solve the expression for x

2x > arcsin(1)

2x > π

x > π/2

This shows that the statement that could be false on the interval is if x is greater than π/2
