Riley rides his bicycle 1.8 km to Jillian’s house. On the way back, he takes a route that is 740 m shorter than the first route.

postnew [5]

1.8 km >> 1,800 m
1,800 - 740 = 1,060 m
1,060 m >> 1.06 km
The shorter route is 1.06 km.

Answer:

it 5.5⋅10−^8m

Step-by-step explanation:

Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer the wavelength associated with the orange light is, subtract the wavelength of the green light from the wavelength of the orange light. You know that the two measured wavelengths are 6.15 ⋅ 10 − 7 m → orange light 5.6 ⋅ 10 − 7 m → green light Therefore, the difference between the two wavelengths will be Δ wavelength = 6.15 ⋅ 10 − 7 m − 5.6 ⋅ 10 − 7 m = 5.5 ⋅ 10 − 8 m

According to a study by de Anna students, the height for Asian adult males is normally distributed with an average of 66 inches

Maslowich

A. X ~ N(66, 6.25)

b. $z_{1} =\frac{65-66}{2.5}=-0.4$
$z_{2} =\frac{69-66}{2.5}=1.2$
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403

c. z= 0.524 and -0.524
$0.524=\frac{X-66}{2.5}$
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4

What is the constant of proportionality of y to x?

AleksAgata [21]

<u>Answer:</u>

2.5

<u>Step-by-step explanation:</u>

We are given a graph with a positive slope where the value of y increases when the value of x increases.

For the given graph, we are to find the constant of proportionality of y to x which is the slope of the given line.

We know the formula of the slope = $\frac{y_2-y_1} {x_2-x_1}$

Substituting the given values in the formula:

$\frac{15-10}{6-4} = \frac{5}{2} = 2.5$

How you would solve the following problem: 4.5 + h = 7.3.

DENIUS [597]

You need to form an algebraic equation. 4.5+h=7.3 therefore h= 7.3 - 4.5 when you take 4.5 to the other side it becomes negative therefore the answer is 2.8.
