Answer:

47378.31625 Liters

Step-by-step explanation:

A fountain holds 12500 7/8 gallons of water. Joe wants to calculate how many liters that is. Which proportion could he use to solve for the number of liters? (1 gal = 3.79 L)

From the above question,

1 gallon = 3.79 Liters

12500 7/8 gallons = x Liters

Cross Multiply

x Liters = 12500 7/8 × 3.79 Liters

x = 47378.31625 Liters

Therefore, the number of liters of water in the fountain is 47378.31625 Liters

The function c= 1.50(n-2) +5.50 represents the costs c in dollars of printing n invitation. Which of the following is not true
ratelena [41]
For this case we have the following equation:
 
 Where,
 n: number of invitations:
 c: cost in dollars
 We note that the slope of the line for this case is:
 
 The slope represents the cost of printing each of the invitations.
 Therefore, it is false that the cost of printing each invitation is $ 5.50
 Answer:
 the following is not true:
 A) each invitation costs $ 5.50 to print.

I hope this helped you! Good luck!

Find the x- and y-intercepts of the graph of 7x + 6y = 21. State your answers as
Amanda [17]
To find the x-intercept, set y=0 and solve for x.
To find the y-intercept, set x=0 and solve for y.

7x+6y=21

x-int: y=0
7x+6(0)=21
7x=21
x=3

y-int: x=0
7(0)+6y=21
6y=21
y=21/6 or 7/2

<h3>Answer:  103</h3>

Explanation:

The term "bisect" means "divide in half", or "divide in two equal pieces".

Angles A = 58 and B = 96 divide in half to get 29 and 48 respectively

Find their sum and subtract it from 180 to get angle AMB

29+48 = 77

180-77 = 103

Matthew participates in a study that is looking at how confident students at SUNY Albany are. The mean score on the scale is 50.
Alex Ar [27]

Answer:

b) 6.68%

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.

The mean score on the scale is 50. The distribution has a standard deviation of 10.

This means that \mu = 50, \sigma = 10

Matthew scores a 65. What percentage of people could be expected to score the same as Matthew or higher on this scale?

The proportion is 1 subtracted by the p-value of Z when X = 65. So

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

Z = \frac{65 - 50}{10}

Z = 1.5

Z = 1.5 has a p-value of 0.9332.

1 - 0.9332 = 0.0668

0.0668*100% = 6.68%

So the correct answer is given by option b.
