The doctor prescribes Sam a 140 ml bottle of medicine with the instructions to take 5 ml twice a day. How long does the medicine last? Show your solution

Answer:

Step-by-step explanation:

Solve for x=0 and x=1

y(0)=2(3^0)=2(1)=2 so (0,2) is a point.

y(1)=2(3^1)=2(3)=6 so (1,6) is a point.

Only graph B has those two points.

Answer:

The correct answer is C. 27 ft, 45 ft, 63 ft.

Step-by-step explanation:

Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:

3 + 5 + 7 = 15

135/15 = 9

9 x 3 = 27

9 x 5 = 45

9 x 7 = 63

Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.

Answer:

2/6

Step-by-step explanation:

Since you already have 6 socks in total and you already know 4 of the color socks are either green or blue, all you would have to do is 6-4 to equal 2 and therefor making 2/6

Answer:

Step-by-step explanation:

ax² + bx + c = y

Plug in data points to get a system of equations in three unknowns.

(0.5,18): 0.25a + 0.5b + c = 18

(1,24): a + b + c = 24

(1.5,22): 2.25a + 1.5b + c = 22

Solving the system:  a = -16, b = 36, c = 4

y = -16x² + 36x + 4

When x = 1.7, y = -16·1.7² + 36·1.7 + 4 = 18.96 ft

Answer:

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:

[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)

Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.

Then, we clear the variable within (1):

[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]

[tex]x = 13.233\,cm[/tex]

The side of the hypotenuse is 12.233 centimeters.

Answer:

3 gallons & 2 quarts.

Step-by-step explanation:

9 gallons & 1 quart - 5 gallons & 3 quarts

well, we know there are 4 quarts in a gallon

9 - 5 = 4, but we would break one gallon into 4 quarts to make subtracting the quarts easier, making it 3 gallons

5 quarts - 3 quarts = 2 quarts

your answer is 3 gallons & 2 quarts, have a nice day

Answer:

95% confidence interval for the percentage of students who change their major

(0.69881 , 0.86119)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the sample proprtion

                        p = 78% = 0.78

Level of significance =0.05

Critical value Z₀.₀₅ = 1.96

Step(ii):-

The 95% of confidence interval is determined by

[tex](p^{-} -Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} +Z_{0.05} \frac{\sqrt{p(1-p)} )}{\sqrt{n} })[/tex]

[tex](0.78 - 1.96 \frac{\sqrt{0.78(1-0.78)} }{\sqrt{100} } , 0.78 +1.96 \frac{\sqrt{0.78(1-0.78} )}{\sqrt{100} })[/tex]

(0.78 -  0.08119,0.78 + 0.08119 )

(0.69881 , 0.86119)

Final answer:-

95% confidence interval for the percentage of students who change their major

(0.69881 , 0.86119)

Answer:

1hr 44 mins

Step-by-step explanation:

Answer:

2 hours and 24 minutes

Step-by-step explanation:

4.38 - 6.22 = 1.84 (the one would be and hour and the 84 would be minutes)

84 - 60 = 24 (60 minutes equal an hour)

2 hours and 24 minutes would be your answer

Answer:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

Step-by-step explanation:

Charge for walking a dog = $20 per dog

Number of dogs = x

Amount charged to walk a dog in a day = y

Unit rate = 20

Equation to represent this is: y = 20x

Let's use this to form a table for walking 1 to 8 dogs:

For 1 dog (x):

y = 20(1) = $20

For 2 dogs (x):

y = 20(2) = $40

For 3 dogs(x):

y = 20(3) = $60

For 4 dogs:

y = 20(4) = $80

And so on till we get to tl8 dogs.

This, we should have the following table:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

To solve this inequality you need to add 2 to both sides.

Which means the answer is add, but I will solve it in this explanation too.

x-2≤1

x-2+2≤1+2

x≤3

Hope this answer helped!
