Based on the picture, did you mean 2 miles vs. 3,526 yards? If so, here's how to solve it:

1 mile is 1760 yds. So 2 miles is 3520 yards.

Therefore, 3526 is longer than 2 miles.

Answer:

51/28

Step-by-step explanation:

Start by making common denominators.

<u>7</u>       <u>2</u>

4       4

Now subtract the two.

7   -    2  = <u>5</u>

                 4

Now you have to make common denominators for the second part, 4/7

<u>16</u>  +  <u>35</u> = <u>51</u>

The lifetime of a certain type of TV tube has a normal distribution with a mean of 61 and a standard deviation of 6 months. What
Ad libitum [116K]

Answer:

P(57

P(-0.67

P(-0.67

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the lifetime for a TV of a population, and for this case we know the distribution for X is given by:

X \sim N(61,6)  

Where \mu=61 and \sigma=6

We are interested on this probability

P(57

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(57

And we can find this probability like this:

P(-0.67

And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.  

P(-0.67

(50 points) Which graph is defined by the function given below?
marta [7]

Answer:

Graph B

Step-by-step explanation:

y = (x - 3)(x - 3)

The x intercepts are at 3

Since both intercepts are at 3, the vertex is at 3

We know it is an upwards facing parabola since it is quadratic and the constant out front is positive
