For this case we have the following variables:
 d = distance
 h = number of hours
 The equation for this case is given by:
 d = 10 * h
 Answer:
 
An equation that relates the distance, that Lisa travels to the number of hours, she has ridden is:
 
d = 10 * h

Help I need this ASAP
ddd [48]

Answer:

1. 7:1

2. 1:8

Step-by-step explanation:

1. Start by counting the number of triangles. We see: 56 triangles. Then, count the hearts. We see: 8 hearts.

So, the ratio of triangles to hearts is 56:8 which we simplify to get: 7:1.

2. Start by adding triangles to hearts. We get: 56+8 which equals 64.

The amount of hearts equals 8 so the ratio of hearts to (hearts + triangle) is! 8:64 which equals 1:8.

step 1

Subtract 14 from 50

50-14=36

so

p+14\leq50

If you solve for p

p\leq36

the answer is the second option

Weights of cars passing over a bridge part 2<br>​
DaniilM [7]

Step-by-step explanation:

The solution to this problem is very much similar to your previous ones, already answered by Sqdancefan.

Given:

mean,  mu = 3550 lbs (hope I read the first five correctly, and it's not a six)

standard deviation, sigma = 870 lbs

weights are normally distributed, and assume large samples.

Probability to be estimated between W1=2800 and W2=4500 lbs.

Solution:

We calculate Z-scores for each of the limits in order to estimate probabilities from tables.

For W1 (lower limit),

Z1=(W1-mu)/sigma = (2800 - 3550)/870 = -.862069

From tables, P(Z<Z1) = 0.194325

For W2 (upper limit):

Z2=(W2-mu)/sigma = (4500-3550)/879 = 1.091954

From tables, P(Z<Z2) = 0.862573

Therefore probability that weight is between W1 and W2 is

P( W1 < W < W2 )

= P(Z1 < Z < Z2)

= P(Z<Z2) - P(Z<Z1)

= 0.862573 - 0.194325

= 0.668248

= 0.67 (to the hundredth)

I have to determine whether the sides of the triangle form a pythagorean triple.​
Crazy boy [7]

Answer:

Step-by-step explanation:

How do you know if side lengths form a Pythagorean triple?

Pythagorean triples may also help us to find the missing side of a right triangle faster. If two sides of a right triangle form part of a triple then we can know the value of the third side without having to calculate using the Pythagorean theorem. From the ratio, we know that it is a Pythagorean triple.
