3-4^2+6/2
we use PEMDAS
since there’s no parentheses we go to exponents
3-16+6/2
Next would be multiplication but there’s nothing to multiply so we go to division
3-16+3
Then we add
3-19
The last and final step is subtraction
-16

Together, Aanya and Krish can wash and wax Aanya's car in 50 minutes. Alone it takes Krish ten minutes more than Aanya. To the n

Leto [7]

Answer:

95 ; 105

Step-by-step explanation:

Let :

Aanya's time = x

Krish's time = x + 10

Together = 50

Hence

Aanya's rate = 1/x

Krish's rate = 1/(x + 10)

Together rate = 1/50

Hence,

1/x + 1/(x + 10) = 1 / 50

((x + 10) + x) / x(x + 10) = 1/ 50

(2x + 10)/ x² + 10x = 1/50

50(2x + 10) = x² + 10x

100x + 500 = x² + 10x

x² + 10x - 100x - 500 = 0

x² - 90x - 500 = 0

Using the quadratic equation solver :

x = 95.24 ; x = - 5.24

Time can't be negative

Hence, x = 95 (nearest minute)

It takes Aanya 95 minutes Alone a ND

Krishna (95 + 10) = 105 minutes alone

(T x 2) - 14 For t=46

o-na [289]

Answer:

Step-by-step explanation:

Use PEMDAS for questions like these (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction) It gives an order in which you should solve the problem. In this case, put 46 instead of T to get (46*2)-14. If we look at PEMDAS, it shows that we need to do what is in the parenthesis first. So, 46x2=92. You get 92-14. Solve that and you get 78

Step-by-step explanation:

1. Statistics is the mean of the sample taken - The average speed that the 250 randomly selected drivers drove on Highway 50

2. Sample is the representative part of the population - The 250 randomly selected drivers who were on Highway 50

3. Population is the group of people from which the sample was taken - All people who drive on Highway 50

4. Variable is a quantity that has values which differ - The speed that a driver drives on Highway

5. Data is information obtained used for a specific purpose - The list of the 250 speeds that the drivers studied drove

6. Parameter is the mean of a population - The average speed that all drivers go on Highway 50
