Step-by-step explanation:
Yes, because the population values appear to be normally distributed
solve for t in d =rt if d =57 and r =30. t=
57 = 30 × t
t = 57/30
t = 19 × 3 / 10 × 3
t = 19/10
t = 1.9
Answer:
t = 1.9
Step-by-step explanation:
Given
d = rt
Substitute d = 57 and r = 30 into the equation
57 = 30t ( divide both sides by 30 )
[tex]\frac{57}{30}[/tex] = t , that is
t = 1.9

Answer: x = 2
Step-by-step explanation:
4x + 4 = 2x + 8
2x = 4
x = 2
Answer: x = 2.
Step-by-step explanation: 4x+4=2x+8 subtract 4 from both sides.
4x = 2x+4 subtract 2x on both sides
2x = 4 divide both sides by two
x = 2

Step-by-step explanation:
Thanks to the given information we can say that the smallest leg is 5 because the triangle is half of an equaliteral one.
for the same reason we can say that x is 5√3 that is the simplest from of the result of the Pytaghorean theorem
the price of a photography machine in RS60000.find the price after inculding13%tax
Answer:
Rs. 67800
Step-by-step explanation:
Price of photograph = 60000 = 100%
Tax = x dollars = 13% of 60000
100% + 13% = 113% = 1.13
Multiply
1.13(60000) = 67800
To check, lets find 13% of 60000 and add to 60000
13% = 0.13
0.13(60000) = 7800
60000 + 7800 = 67800
Units = Rs
Rs. 67800

a small chocolate sundae costs $3. each topping you add costs $0.50. how much would it cost to get a small sundae with P toppings added?
Answer:
3=0.5p
Step-by-step explanation:
The cost to get a small sundae with P toppings added represented as 3 + 0.5p.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let's consider the toppings added to the chocolate sundae represented by p.
We will use the unitary method,
The cost of topping added to one chocolate = $0.50
The cost of topping added to p chocolate = $0.5p
So, the cost to get a small sundae with P toppings added is;
3 + 0.5p
Therefore, the cost to get a small sundae with P toppings added represented as 3 + 0.5p

The solution to the quadratic equation x² - 4x + 1 = 0 is x = ( 4 ±√12 ) / 2
What is the solution to the quadratic equation?A quadratic equation in its standard form is expressed as;
ax² + bx + c = 0
Where x is the unknown
To solve for x, we use the quadratic formula
x = (-b±√(b² - 4ac)) / (2a)
Given the quadratic equation in the question;
x² - 4x + 1 = 0
a = 1b = -4c = 1We substitute this values into the quadratic formula above and solve for x.
x = (-b±√(b² - 4ac)) / (2a)
x = ( -(-4) ±√( (-4)² - ( 4 × 1 × 1)) / (2 × 1)
x = ( 4 ±√( 16 - 4) ) / (2)
x = ( 4 ±√12 ) / 2
Therefore, ( 4 ±√12 ) / 2 is the solution to the equation.
Option C) ( 4 ±√12 ) / 2 is the correct answer.

Dr. Porterfield has a choice of bread (pink, purple), meat (ham, turkey, beef) and Cheese (American, Swiss, Portugues, Japanese) at a sandwich shop. What is the probability he will select a sandwich on purple bread with either beef or turkey and has Japanese cheese
Answer:
The probability is 0.08[tex]\overline 3[/tex]
Step-by-step explanation:
The choice of bread Dr Porterfield has = Pink, purple
The number of types of breads = 2
The choices of meat = Ham, turkey, beef
The number of types of meat = 3
The choice of cheese = American, Swiss, Portuguese, Japanese
The number of types of cheese = 4
The probability of selecting purple bread from pink or purple = 1/2
The probability of selecting beef or turkey from the 3 choices of meat = 2/3
The probability of selecting Japanese cheese from the fourvtypes of cheese = 1/4
Therefore, the probability he will select a sandwich on purple bread with either beef or turkey and has Japanese cheese = (1/2) × (2/3) × (1/4) = 2/24 = 1/12 = 0.08[tex]\overline 3[/tex]

What is the fraction representation of 0.196 (6 repeating)?
Answer:
49/250 I think I'm not sure though
Answer:
[tex]\frac{59}{300}[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}[/tex] returns the decimal [tex]0.\overline{x}[/tex]. In this case, we only want the 6 repeating. We can achieve this by finding the fraction excluding the 6 and then adding the repeating fraction with the 6.
0.19 as a fraction is simply [tex]\frac{19}{100}[/tex]
[tex]\frac{6}{9}[/tex] returns a repeating digit 6. However, we would like the 6 to be in the thousands place. Since it's already in the tenth place, we will divide the fraction by 100 to put it in the thousands place: [tex]\frac{6}{9}\cdot \frac{1}{100}=\frac{6}{900}[/tex]
Adding these two fractions, we get:
[tex]\frac{6}{900}+\frac{19}{100}=\frac{6}{900}+\frac{171}{900}=\frac{177}{900}=\boxed{\frac{59}{300}}[/tex]

Answer:
7) [tex]x \to x - 3[/tex].
8) [tex]y \to y + 2[/tex]
9) The entire quadratic equation did not get reflected.
Step-by-step explanation:
7) A horizontal translation to the right is of the form:
[tex]x \to x - a[/tex]
Let [tex]y = -(x-3)^{2} + 2[/tex], then the horizontal translation is represented by [tex]x \to x - 3[/tex].
8) A vertical translation upwards is of the form:
[tex]y \to y + a[/tex]
Let [tex]y = -(x-3)^{2} + 2[/tex] , then the vertical translation is represented by:
[tex]y \to y + 2[/tex]
9) The only component of the quadratic equation that was reflected was the part [tex](x-3) ^{2}[/tex] along the x-axis. We can create the entire function by applying the following steps:
(i) [tex]f(x) = x^{2}[/tex] (Original function)
(ii) [tex]f(x) = (x-3)^{2}[/tex] (Horizontal translation)
(iii) [tex]f(x) = - (x-3)^{2}[/tex] (Reflection)
(iv) [tex]f(x) = -(x-3)^{2} + 2[/tex] (Vertical translation)
The entire quadratic equation did not get reflected.
