Note the graph of an athletes performance after finishing a triathlon. The x-axis measures time in hours, and the y axis measure

s distance in kilometers. First she swam, then biked, and then she finished the race with a run. The data states she ran four times as fast as she swam and she biked twice as fast and she ran. Based on the graph, chose the statement below that is false.
A) the steeper the segment, the faster the athlete is traveling along the course

B) the athlete finished the course in under eight hours

C) the athlete spent equal amounts of time biking and running

D) the athlete spent twice as much time biking compared to swimming

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 3903
polet [3.4K]

Answer:

0.9861 = 98.61% probability that the weight will be less than 4884 grams.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean weight of 3903 grams and a standard deviation of 446 grams.

This means that \mu = 3903, \sigma = 446

If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be less than 4884 grams.

P-value of z when X = 4884. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{4884 - 3903}{446}

Z = 2.2

Z = 2.2 has a p-value of 0.9861

0.9861 = 98.61% probability that the weight will be less than 4884 grams.

Solve for Zeros by factoring <br> 5x^2 + 13x - 6
serious [3.7K]
5x^2+13x-6

Break  the expression into groups:

=(5x^2-2x)+(15x-6)

Factor out x from : 5x^2-2x = x(5x-2)

Factor out 3 from : 15x-6=3(5x-2)

=x(5x-2)+3(5x-2)

Factor out common term (5x-2)

= (5x-2)(x+3)

hope this helps!

What is the equation for the graph shown?
Kamila [148]

Answer:

y = 2x/3 + 4

Step-by-step explanation:

The line passes through (-6, 0) and (0, 4)

slope = (4 - 0)/(0 - (-6)) = 4/6 = 2/3

y = (2/3)x + b

when x = 0, y = 4, so

4 = (2/3)*0 + b

b = 4

so

y = 2x/3 + 4

Find the range of values for which<br>x2–5x + 6 &lt; 0​
meriva

Answer:

-2<x<3

or x∈(-2,3)

Step-by-step explanation:

x²-5x<-6

add (-5/2)² i.e.,25/4

x²-5x+25/4<-6+25/4

(x-5/2)²<(-24+25)/4

(x-5/2)²<1/4

(x-5/2)²<(1/2)²

|x-5/2|<1/2

-1/2<x-5/2<1/2

Add 5/2

-1/2+5/2<x-5/2+5/2<1/2+5/2

-2<x<3
