The first thing we must do for this case is to define variables:
x: text messages
Y: pictures
We write the system of equations:
0.05x + 0.10y = 4
x = y + 5
Solving the system we have:
x = 30
y = 25
Answer:
you send:
30 text messages
25 pictures
Answer:
Step-by-step explanation:
To get from blue to red you need to multiply the blue dimensions by 1.5.
4*x = 6 Divide by 4
x = 6/4
x = 1.5
The surface area is a different ball game.
SA of the blue figure
Surface area of 1 side = 4 * 4 = 16
The total surface area = 16* 6 = 96
SA of the red figure
Surface area of 1 face = 6*6
Surface area of 6 faces = 6 * 36 = 216
So what's the ratio ?
Ratio = red surface area/ blue surface area
Ratio = 216 / 96 = 2.25
Notice that if you square the dimensional ratio, you get the area ratio
1.5^2 = 2.25
<span>Yes, this would be considered a function of time elapsed. To be a function, there needs to be exactly a one-to-one relationship between the variables. At any one time (elapsed since midnight), there is exactly one value for the number of calories burned.</span>
Answer:
c = 0.1864
Step-by-step explanation:
To find c, we need to find the z-score where:
P(-z<Z<z) = 98%
Based on the properties of the normal distribution we can said that
P(-z<Z<z) = 98% is equal to:
2*P(Z>z) = 2% or P(Z>z)= 1%
So, using the standard normal table, the z score is 2.33
Then, we can calculated the value of c as:

Where s is the standard deviation and z is the z-score. Replacing the values, we get:
c = 2.33*0.08
c = 0.1864
