A 4-sided figure has 4 corners labeled E, G, D, C starting from the top-left corner and going clockwise. A line cuts through the

shape from point C to point G and contains point F. Another line cuts through the shape from E to point F. Angle C E G is a right angle. Based on the diagram, which reason justifies this statement? If ∠CEF is complementary to ∠DCF, then ∠DCF ≅ ∠FEG. Complements of the same angle are congruent. Complements of congruent angles are congruent. Supplements of the same angle are congruent. Supplements of congruent angles are congruent.

Which function has a range of y < 3?
Setler79 [48]

Using a graphing tool

Let's graph each of the cases to determine the solution of the problem

<u>case A)</u> y=3(2^{x})  

see the attached figure N 1

The range is the interval--------> (0,∞)

y> 0

therefore

the function y=3(2^{x}) is not the solution

<u>case B)</u> y=2(3^{x})

see the attached figure N 2  

The range is the interval--------> (0,∞)

y> 0

therefore

the function y=2(3^{x}) is not the solution

<u>case C)</u> y=-2^{x}+3  

see the attached figure N 3    

The range is the interval--------> (-∞,3)  

y< 3

therefore

the function   y=-2^{x}+3    is the solution

<u>case D)</u> y=2^{x}-3  

see the attached figure N 4  

The range is the interval--------> (-3,∞)  

y>-3

therefore

the functiony=2^{x}-3 is not the solution

<u>the answer is</u>

y=-2^{x}+3

A normal distribution curve, where x = 70 and σ = 15, was created by a teacher using her students’ grades. What information abou
mash [69]

Answer:

The median and mode of the students grade is 70.

Most of the students scored between 40 and 100.

Step-by-step explanation:

From the provided information it can be seen that the mean of the distribution is, <em>μ</em> = 70 and the standard deviation is, <em>σ</em> = 15.

For a Normal distributed data the mean, median and mode are the same.

So, the median and mode of the students grade is 70.

The standard deviation of the data represents the spread of the observation, i.e. how dispersed the values are along the curve.

In statistics, the 68–95–99.7 rule, also recognized as the empirical rule, is a shortcut used to recall that 68.27%, 95.45% and 99.73% of the values of a Normally distributed data lie within one, two and three standard deviations of the mean, respectively.

P(\mu-\sigma  

P(\mu-2\sigma

P(\mu-3\sigma

Assuming that maximum marks of the exam is 100, it can be said that most of the students scored between 40 and 100.

A quarter is approximately 0.07 inches thick. A dollar bill is approximately 4.3 × 10-3 inches thick.
nlexa [21]

Answer:

m = 6.57 and n = -2

Step-by-step explanation:

To answer this question you will covert the thickness of a dollar to standard notation and then compare the two values.

0.07 =compared to 0.0043 = 0.0657

0.0657 = 6.57 x 10^-2

A quarter is thicker than a dollar by 6.57 x 10^-2.

m = 6.57 and n = -2

Your drawer has 5 pairs of black socks, 4 pairs of gray socks, 2 pairs of white socks, 1 pair of brown socks, and 1 pair of blue
Sergeeva-Olga [200]
5 pairs of black socks*2 because it’s a pair= 10 socks
4 pairs of grey socks*2=8
2 pairs of white socks*2=4
1 pair of brown socks*2=2
1 pair of blue socks*2=2
10 socks+8 socks+4 socks+2 socks+ 2 socks=26 socks in total
26/2=13+1 because you need to be sure you get one pair of socks. The smallest amount of socks you would have to grab to get at least one matching pair is 14 socks.
