Answer:

6 7/8 inches

Step-by-step explanation:

The first thing to do is to get the measurements in either inches or feet.  You can't have both.  Let's go from feet to inches.

3 feet = 36 inches

13.75 feet = 165 inches

Now we can set up a proportion to solve for the number of inches the model is:

\frac{model}{real}:\frac{1.5}{36}  =\frac{x}{165}

Now we can cross multiply:

36x = 247.5 so

x = 6.875 or 6 7/8 inches

Answer:

The probability that on a given day below 6,214,323 drinks are sold is 0.8413.

Step-by-step explanation:

The provided information are:

Population mean (\mu) = 6,205,195

Population standard deviation (\sigma) = 9,120.32

Consider, <em>X</em> be the random variable that represents the number of drinks that are sold on a given that is normally distributed with the mean = 6,205,195 and standard deviation = 9,120.32.

The probability that on a given day below 6,214,323 drinks are sold can be calculated as:

P(X

It must be noted that <em>P</em>(<em>Z</em> < 1.0008) = 0.8413 has been calculated using the standard normal table.

Hence, the required probability is 0.8413.

The measure of an angle is 17°. What is the measure of its complementary angle?
lions [1.4K]

Answer:

73°

Step-by-step explanation:

the measure of two complementary angles add up to 90

so We need to solve this equation to get the measure of its complementary angle :

x + 17 = 90

then

x = 90 - 17

  = 73

Please help me undertsand this question.

So basically, you want to show why the two lines (m and n ) are the "same". To show this you would say <4 &<5 are also supplementary because it is the same as <3 & <6. I think this is what the question is asking. To prove this you use the Converse Theorem. Which is what I just showed you with the angles.
