You would take 170 pieces of candy and divide it among 45 boys

170/45 = about 3 pieces each with a few remaining

Use the drop-down menus to complete each equation so the statement about its solution is true.
aleksklad [387]

First, let's simplify the expression: 7 - 5 + 3x - 1  ⇒   3x + 1  <em>(slope=3, y-intercept = 1)</em>

Next, let's understand what they are asking for:

<u>no solutions</u> means same slope but different y-intercepts

Answer: 3x + _______ (the blank can be anything except 1)

<u>one solution</u> means different slopes

Answer: ________x + _______ (the first blank can be anything except 3, the second blank can be anything)

<u>infinitely many solutions</u> means same slope and same y-intercept

Answer: 3x + 1

1Y, the number of accidents per year at a given intersection, is assumed to have a Poisson distribution. Over the past few years
miss Akunina [59]

Answer:

The probability that the intersection will come under the emergency program is 0.1587.

Step-by-step explanation:

Lets divide the problem in months rather than in years, because it is more suitable to divide the period to make a better approximation. If there were 36 accidents in average per year, then there should be 3 accidents per month in average. We can give for the amount of accidents each month a Possion distribution with mean 3 and variance 3.

Since we want to observe what happen in a period of one year, we will use a sample of 12 months and we will take its mean. We need, in average, more than 45/12 = 3.75 accidents per month to confirm that the intersection will come under the emergency program.

For the central Limit theorem, the sample mean will have a distribution Normal with mean 3 and variance 3/12 = 0.25; thus its standard deviation is √0.25 = 1/2.

Lets call the sample mean distribution X. We can standarize X obtaining a standard Normal random variable W with distribution N(0,1).

W = \frac{X-\mu}{\sigma} = \frac{X-3}{1/2} = 2x-6

The values of \phi , the cummulative distribution function of W, can be found in the attached file. We are now ready to compute the probability of X being greater than 3.75, or equivalently, the probability than in a given year the amount of accidents is greater than 45, leading the intersection into an emergency program

P(X > 3.75) = P(2X-6 > 2*3.75-6) = P(W > 1) = 1-\phi(1) = 1-0.8413 \\= 0.1587

5. Find the mZABC if<br> ZABD = 35°, ZDBC = 55º.
Reika [66]

Answer:

m\angle ABC=90^o

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m\angle ABC=m\angle ABD+m\angle DBC ----> by angle addition postulate

substitute the given values

m\angle ABC=35^o+55^o=90^o

Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d
iogann1982 [59]
<span>Form a sequence that has two arithmetic means between -13 and 89. a. -13, 33, 43, 89 c. -13, 21, 55, 89 b. -18, -36, -72, -144 d. -18, -81, -144

Solution:

Since  it has to be between -13 and 89, letter d and b are not anymore considered to be the answer.

for a:
33-(-13)=46=d
43-33=10=d the value for this d is different from the two sequence,
89-43=46=d
they have different value for d, thus this is not the answer!

for c:
21-(-13)=34=d
55-21=34=d
89-55=34=d

they have the same value for d, thus the correct answer is </span><span> c. -13, 21, 55, 89</span>
