Answer:
c<190
Step-by-step explanation:
Step 1: Subtract 670 from both sides.
7c+670−670<2000−670
7c<1330
Step 2: Divide both sides by 7.
7c 7 <
1330
7
anyways thjis would be the answer c<190

Step-by-step explanation:
Gold’s gym charges $30 membership fee plus $3 for each workout, while Titletown charges $40 membership fee plus $1 for each workout.
Let x = number of workouts
Let y = total costs
Gold's Gym: y = 30 + 3x
Titletown Fitness: y = 40 + x
How many workouts does a person have to do until the total costs are equal?
Answer:
5 workouts should be performed to equalize the costs between both gyms.
Step-by-step explanation:
Given that Gold’s gym charges $ 30 membership fee plus $ 3 for each workout, while Titletown charges $ 40 membership fee plus $ 1 for each workout, to determine how many workouts does a person have to do until the total costs are equal, the following calculation must be performed:
Gold's Gym: y = 30 + 3x
Titletown Fitness: y = 40 + x
Gold's Gym: y = 30 + 3x2 = 36
Titletown Fitness: y = 40 + 2 = 42
Gold's Gym: y = 30 + 3x3 = 39
Titletown Fitness: y = 40 + 3 = 43
Gold's Gym: y = 30 + 3x4 = 42
Titletown Fitness: y = 40 + 4 = 44
Gold's Gym: y = 30 + 3x5 = 45
Titletown Fitness: y = 40 + 5 = 45
Thus, 5 workouts should be performed to equalize the costs between both gyms.

Assume a test for a disease has a probability 0.05 of incorrectly identifying an individual as infected (False Positive), and a probability 0.01 of incorrectly identifying an individual as uninfected (False Negative). Assume furthermore that the probability of an individual being infected is 0.000001 (1 in 1 million). If a person tests positive for this disease, what is the probability of actually having the disease
Answer:
0.00002 = 0.002% probability of actually having the disease
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: Positive test
Event B: Having the disease
Probability of having a positive test:
0.05 of 1 - 0.000001(false positive)
0.99 of 0.000001 positive. So
[tex]P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094[/tex]
Probability of a positive test and having the disease:
0.99 of 0.000001. So
[tex]P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}[/tex]
What is the probability of actually having the disease
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{9.9 \times 10^{-7}}{0.05000094} = 0.00002[/tex]
0.00002 = 0.002% probability of actually having the disease
A standard six-sided die is rolled.
What is the probability of rolling a number greater than or equal to 3? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Tables
Keypad
Answer:
Step-by-step explanation:
There are six sides on the die...
1, 2, 3, 4, 5, 6
Greater than or equal to 3 includes 3, 4, 5, 6
This means 4 out of 6, or 4/6
4/6 simplified is 2/3

Answer:
[tex] \sqrt{32} + 3[/tex]
[tex] - \sqrt{32} + 3[/tex]
Step-by-step explanation:
Use foil method
[tex](y - 3) {}^{2} [/tex]
[tex](y - 3)( y - 3)[/tex]
First multiply y and y
[tex]y \times y = {y}^{2} [/tex]
Next Multiply Outer term y and -3.
[tex]y \times - 3 = - 3y[/tex]
After that ), Multily inner tern -3 and y
[tex] - 3 \times y = - 3y[/tex]
Finally multiply -3 and -3 and you get 9.
Then combine all
[tex] {y}^{2} - 6y + 9 - 32 [/tex]
[tex] {y}^{2} - 6y - 23[/tex]
Now I'm going to complete the square. First get only the y value on the left side so we first set this equal to zero then move add 23 on both sides.
[tex] {y}^{2} - 6y - 23 = 0[/tex]
Add 23
[tex]y {}^{2} - 6y = 23[/tex]
Apply formula
[tex] (\frac{b}{2} ) {}^{2} [/tex]
where b is the coefficient.
plug it in
[tex]( \frac{ - 6}{2}) {}^{2} [/tex]
Which is -3 squared which equal 9.
Then add 9 on both sides
[tex] {y}^{2} - 6y + 9 = 23 + 9[/tex]
23+9=32
Now let factor the left side
the only number that adds to -6 and multiply to 9 is
-3 so we would rewrite the left side as
[tex](x - 3) {}^{2} = 32[/tex]
Now take the sqr root of 32
[tex] \sqrt{(x - 3) {}^{2} } = \sqrt{32} [/tex]
Then add 3 on both sides
[tex]x + - 3 + 3 = \sqrt{32} + 3[/tex]
A sqr root of a number can be positive or negative so
the answer is
[tex] - \sqrt{32} + 3[/tex]
[tex] \sqrt{32} + 3[/tex]

Ben Frank is an electrician who installs lighting fixtures. He charges (in dollars) his clients 15h +40f
where h is the number of hours worked and f is the number of fixtures installed.
How much does Ben Frank charge when he works 7 hours and installs 9 fixtures?
Answer:
465 Dollars
Step-by-step explanation:
15h+40f = Amount Charged
if: h = 7
f = 9
15(7)+40(9) = Amount Charged
105 + 360 = Amount Charged
465 = Amount Charged
He will charge 465 dollars.
15h + 40f
Step 2:= 15(7) + 40(9)
Step 3:= 105 + 360
Step 4:= $465

Answer•Pic on the left
x = 8.36
y = 140.18°
• Pic on the right
x = 110°
Way to do• This one for the pic on the left
#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)
#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D
90 = (5x - 2) + 6x
90 = 11x - 2
90 + 2 = 11x
92 = 11x
x = 92 : 11
x = 8.36 (2 decimal places)
#Now you know the x, you can now find the degree
#degree of (5x - 2)
5x - 2 =
5(8.36) - 2 =
41.81 - 2 = 39.81
#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)
180° - 39.81° = 140.18
•This one for the pic on the right
#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.
# Also as i said before, total triangle degree is 360°
#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)
Degree = 180° - 80° - 30° = 70°
#Now you can get x
x = 180° - 70° = 110°

When plotting points on the coordinate plane below, which point would lie on the x-axis?
(6, 0)
(0, 2)
(3, 8)
(5, 5)
Answer: (6,0)
Coordinate points are always written in pairs of the x- and y-coordinate: (x, y). Knowing this, the point would need to have a y-value of 0 in order to lie on the x-axis (otherwise, it would be on a random spot on the grid). The only coordinate point with a y-value of 0 is (6, 0). Therefore, the coordinate point (6, 0) lies on the x-axis.
Please refer to the attached graph below to see all the coordinate points.
