Step-by-step explanation:
this should be right
Answer:
[tex](x + 2)^{2} + y^{2} = 45[/tex]
Step-by-step explanation:
The radius (r) of the circle is the distance between (-2, 0) and (-5, -6)
r = [tex]\sqrt{(-2 + 5)^{2} + (0 + 6)^{2} } = \sqrt{3^{2} + 6^{2} } = \sqrt{9 + 36} = \sqrt{45}[/tex]
[tex]r^{2}[/tex] = 45
[tex](x + 2)^{2} + y^{2} = 45[/tex] is the equation of the circle

Step-by-step explanation:
According to a study in a medical journal, 202 of a sample of 5,990 middle-aged men had developed diabetes. It also found that men who were very active (burning about 3,500 calories daily) were a fourth as likely to develop diabetes compared with men who were sedentary. Assume that one-fifth of all middle-aged men are very active, and the rest are classified as sedentary. What is the probability that a middle-aged man with diabetes is very active
Answer:
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has diabetes.
Event B: Is very active.
Probability of having diabetes:
To find this probability, we take in consideration that:
It also found that men who were very active (burning about 3,500 calories daily) were a fourth as likely to develop diabetes compared with men who were sedentary. Assume that one-fifth of all middle-aged men are very active, and the rest are classified as sedentary.
So the probability of developing diabetes is:
x of 4/5 = x of 0.8(not active)
x/4 = 0.25x of 1/5 = 0.2(very active). So
[tex]P(A) = 0.8x + 0.25*0.2x = 0.85x[/tex]
Probability of developing diabetes while being very active:
0.25x of 0.2. So
[tex]P(A \cap B) = 0.25x*0.2 = 0.05x[/tex]
What is the probability that a middle-aged man with diabetes is very active?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05x}{0.85x} = \frac{0.05}{0.85} = 0.0588[/tex]
0.0588 = 5.88% probability that a middle-aged man with diabetes is very active

The figure shows a vertical section through the
axis of a solid paper weight made in the shape of a right circular cone. Its height is 8 cm and the diameter of its base is 4 cm. The shaded portion is made of lead 2 cm thick while the unshaded portion is made of wood. The density of lead and wood are 11.3 g/cm and 0.9 g/cm respectively.
Find,
(i) the total volume of the paper weight,
(ii) the volume of the wooden portion,
(iii) the total mass of the paper weight.
Answer:
i. 33.51 cm³
ii. 14.14 cm³
iii. 231.61 g
Step-by-step explanation:
(i) the total volume of the paper weight,
Since the paper weight is in the form of a cone, its volume is the volume of a cone V = πD²h/12 where D = diameter of cone = 4 cm and h = height of cone = 8 cm
So, V = πD²h/12
V = π(4 cm)² × 8 cm/12
V = 16π cm² × 8 cm/12
V = 128π cm³/12
V = 402.124 cm³/12
V = 33.51 cm³
(ii) the volume of the wooden portion,
The volume of the wooden portion, V' = πr'²h'/3 where r' = radius of wooden portion and h' = height of wooden portion
From similar triangles in the figure, we have
height of wooden portion, h'/radius of wooden portion, r' = height of paper weight, h/radius of paper weight, r
h'/r' = h/r where r = D/2 where D =diameter of paper weight = 4 cm. So, r = 4 cm/2 = 2 cm
and h' = height of paper weight - height of lead portion = 8 cm - 2 cm = 6 cm
So,
r' = rh'/h = 2 cm × 6 cm/8 cm = 12 cm²/8 cm = 1.5 cm
So, V' = πr'²h'/3
V' = π(1.5 cm)² × 6 cm/3
V' = π2.25 cm² × 2 cm
V' = 4.5π cm³
V' = 14.14 cm³
(iii) the total mass of the paper weight.
The total mass of paper weight, m = mass of wooden portion + mass of lead portion = ρ'V' + ρ"V" where ρ' = density of wood = 0.9 g/cm³, V' = volume of wooden portion = , ρ" = density of lead = 11.3 g/cm³ and V" = volume of lead portion = V - V' = 33.51 cm³ - 14.14 cm³ = 19.37 cm³
So, m = 0.9 g/cm³ × 14.14 cm³ + 11.3 g/cm³ × 19.37 cm³
m = 12.726 g + 218.881 g
m = 231.607
m ≅ 231.61 g

To make 1000 containers of ice cream you need: 600 units of milk, 275 units of cream, and 120 units of flavor. Each ingredient is contained in tanks like the ones pictured below. Note the capacity of each container. Adjustments to one ingredient must be followed by corresponding adjustments to the other ingredients. If the pump on the milk tank pumps milk out at a rate of 50 units per minute, how long would it take to empty the 1000 unit milk tank
Answer:
It will take 20 minutes to pump out 1000 unit milk tank
Step-by-step explanation:
The pump on the milk tank pumps milk out at a rate of 50 units per minute,
1 minute = 50 units
x minutes = 1000 units
Using the unitary method x= = 1000*1/50= 20 minutes
It will take 20 minutes to pump out 1000 unit milk tank

(b) $1340
(c) Debit card
Step-by-step explanation:
(a) The debit card is funded by Jenny's checking account, so it cannot be used to spend more than her checking account balance. The most Jenny can spend using her debit card is $1430.
__
(b) Amounts purchased using her credit card add to the credit balance. The most Jenny can purchase is the difference between her current balance and her credit limit.
Limit - balance = $2350 -1010 = $1340
The most Jenny can spend using her credit card is $1340.
__
(c) For a purchase of $1400, the amount available on Jenny's credit card is insufficient. She can make the purchase using her debit card.

A popular internet subscription service for movies, TV series, and documentaries conducts a survey in which it randomly samples 1,000 of its customers. The survey asks the customers which way they use their streaming service the most: (1) watching movies, (2) watching TV series, or (3) watching documentaries. They also ask the level of satisfaction with the service they most often use (on a scale of 0 to 10 with 0 very poor and 10 excellent). Is there statistical evidence for this internet subscription service that the mean satisfaction differs between customers who watch movies, TV series, or documentaries the most?

The value of point B is greater than the value of point A in this number line.Why is this true?
Answer:
Point B is to the right of point A
Step-by-step explanation:
On a number line, the mid value is usually 0 with positive and negative numbers positioned to the either sides of the midpoint 0, the negative numbers are arranged to the left and the positive numbers are written to the right. With this in mind and the knowledge that positive numbers are always greater than negative numbera. Then we can conclude that point B is greater than point A because point B is positive and point A is negative because point B is to the right of Point A.

D.(3, 3)
Step-by-step explanation:
The equation of a straight line is given as:
y = mx + c;
where x, y are variables, m is the slope of the line, c is the y intercept.
From the graph, we can see that line 1 passes through (6,0) and (0,6).
The equation of line 1 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{6-0}{0-6} (x-6)\\\\y=-x + 6\ \ \ (1)[/tex]
Line 2 passes through (6, 5) and (0, 1)
The equation of line 2 is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-5=\frac{1-5}{0-6} (x-6)\\\\y=\frac{2}{3}x + 1\ \ \ (2)[/tex]
To get the coordinates of the intersection of the two lines, we solve equation 1 and 2 simultaneously using a calculator. This gives:
x = 3, y = 3
Therefore the two lines meet at (3, 3)

Solve the equation x^2 - 16x+ 54 = 0 by completing the square.
Fill in the values of a and b to complete the solutions.
Answer:
[tex]x = 8\±\sqrt{10[/tex]
[tex]a =8[/tex] [tex]b = 10[/tex]
Step-by-step explanation:
Given
[tex]x^2 - 16x + 54 = 0[/tex]
Required
Complete the square
[tex]x^2 - 16x + 54 = 0[/tex]
Subtract 54 from both sides
[tex]x^2 - 16x + 54 -54= 0-54[/tex]
[tex]x^2 - 16x = -54[/tex]
--------------------------------------------------
Take half of - 16
[tex](-16/2) = -8[/tex]
Square the result
[tex](-8)^2 = 64[/tex]
Add the squared result to both sides of the equation
--------------------------------------------------
So, we have:
[tex]x^2 - 16x +64= -54+64[/tex]
[tex]x^2 - 16x +64= 10[/tex]
Expand
[tex]x^2 - 8x - 8x + 64 = 10[/tex]
Factorize
[tex]x(x - 8) - 8(x - 8) = 10[/tex]
Factor out x - 8
[tex](x - 8)(x - 8) = 10[/tex]
[tex](x - 8)^2 = 10[/tex]
Take square roots
[tex]x - 8 = \±\sqrt{10[/tex]
Solve for x
[tex]x = 8\±\sqrt{10[/tex]
We have:
[tex]x = a - \sqrt{b}[/tex]
[tex]x = a + \sqrt{b}[/tex]
By comparing the above with: [tex]x = 8\±\sqrt{10[/tex]
