(A) 1 2 (B) 3 2 (C) 2 (D) 4 (E) 6
Answer:
w = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{y}[/tex] = 6 and x = 36 , then
[tex]\frac{36}{y}[/tex] = 6 ( multiply both sides by y )
36 = 6y ( divide both sides by 6 (
6 = y
Then
[tex]\frac{y}{w}[/tex] = 4 , that is
[tex]\frac{6}{w}[/tex] = 4 ( multiply both sides by w )
6 = 4w ( divide both sides by 4 )
[tex]\frac{6}{4}[/tex] = w , that is
w = [tex]\frac{3}{2}[/tex]
Write each of these propositions in the form "p if and only if q" in English.
a) If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside.
b) For you to win the contest it is necessary and sufficient that you have the only winning ticket.
c) You get promoted only if you have connections, and you have connections only if you get promoted.
d) If you watch television your mind will decay, and conversely.
e) The trains run late on exactly those days when I take it.
Answer:
The "p if and only if q" statement is equivalent to "q if and only if p", then let's rewrite all the propositions in this way.
a) "If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside."
We can define:
q = is hot outside
p = you buy an ice cream cone
Then we can rewrite this as:
"You buy an ice cream cone if and only if is hot outside"
b) "For you to win the contest it is necessary and sufficient that you have the only winning ticket."
We can define:
p = you winning the contest
q = have the winning ticket
Then we can rewrite (changing some words) this as:
"You will win the contest if and only if you have the winning ticke"
c) "You get promoted only if you have connections, and you have connections only if you get promoted."
We can define:
p = you get promoted
q = you have connections
We can rewrite the proposition as:
"You can get promoted if and only if you have connections"
d) " If you watch television your mind will decay, and conversely."
We can define:
p = you watch television
q = your mind will decay
We can rewrite it as:
"You can watch television if and only if your mind decays"
e) " The trains run late on exactly those days when I take it."
We can define:
p = The train runs late
q = I take it.
We can rewrite the proposition as:
"The train runs late if and only if I take it"
Whats 4.87 rounded to the nearest tenths
Answer:
4.9
Step-by-step explanation:
Tenths is the number directly after the "." so the 8 in 4.87 is the tenth. Rounding is quite easy, since 7 is bigger than 5 you add 1 to the 8 thus rounding the 4.87 to 4.9
Answer:
4.90
Step-by-step explanation
in 4.87 the 7 hundredth is closer to 4.90 rather than 4.80

Step-by-step explanation:
J(2,4) → J'(4,8)
K(1,1) → K'(2,2)
L(4,0) → L'(8,0)
Dilate with a scale factor of 2
Each set of JKL points multiplied by 2 to form J'K'L'

Two friends, Neil and Charlie, are going to depart from their houses and ride their bikes towards each other until they meet, and then have a picnic. Neil can bike 11 miles per hour, while Charlie can bike 9 miles per hour. If their houses are connected by a straight road that is 6 miles long, in how long will the two meet?
Answer:
0.3 hour or 18 minutes
Step-by-step explanation:
How long means, we are to calculate the time(t)
Hence,
Speed × time = Distance
For Neil , 11 × t
For Charlie = 9 × t
11t + 9t = 6
20t = 6
t = 6/20
t = 0.3 hour
Converting to minutes
1 hour = 60 minutes
0.3 hour = x
x = 0.3 × 60 minutes
x = 18 minutes
Therefore, it will take 0.3 hour or 18 minutes for these two to meet.

2. Find the values of the six trigonometric functions for angle 0, when AC = 10 and BC = 8.
Answer:
53.13degrees
Step-by-step explanation:
Using the SOH CAH TOA identity'
Sin theta = opposite/hypotenuse
Given
Hypotenuse AC= 10
Opposite BC = 8
Required
theta
Substitute
Sin theta = BC/AC
Sin theta = 8/10
sin theta= 0.8
theta = arcsin0,8
theta = 53.13
Hence the requred angle is 53.13degrees
Each bar includes the left-end value but not the right-end value. For example, the first bar
includes dogs that weigh 60 pounds and 68 pounds but not 80 pounds.
Step-by-step explanation:
Answers:
How many dogs weigh at least 100 pounds?
14 + 5+ 3 + 1 = 23 dogs.
How many dogs weigh exactly 70 pounds?
is unknown, so will be 60-79 .
How many dogs weigh at least 120 and less than 160 pounds?
8 dogs weigh 120 less than 160 pounds.
How much does the heaviest dog at the show weigh?
is unknown, but could be between - 160-179
What would you consider a typical weight for a dog at this dog show? Explain your reasoning.
A typical dog weighs can be 100 - 120.

Preston teaches at an international school. After reading an article about the distribution of the world's population by continent, he wanted to test if the distribution of students in his school was similar. He collected information about all 320 students in his school. Here are the results:
Preston wants to perform x^2 goodness-of-fit test to determine if these results suggest that the distribution of students doesn't match the reported distribution.
What is the expected count of students from Australia in Preston's group?
Answer:
Since there are 320 students, and Preston expects 0.5% of them to be from Australia, the expected count of students from Australia is 0.005 (320) =1.6
The expected count students from Australia is 1.6.
Step-by-step explanation:
The expected count of students from Australia in Preston's group is equal to 1.6.
What is a goodness-of-fit test?A goodness-of-fit test can be defined as a statistical tool that is used to test if sample data fits into a set of observations or distribution from a given population.
This ultimately implies that, a goodness-of-fit test helps to determine whether on not sample data represents the data that are expected in an actual population.
Given the followin data:
Popuation = 320 students.
Expected percent (Preston's group) = 0.5% = 0.005.
Expect count = 0.005 × 320
Expect count = 1.6.

Help please !!!!!!!!!!!
Answer:
See below for answers and explanations to the first 5 problems
Step-by-step explanation:
Problem 1:
cos(x) = 2/3
sec(x) = ?
sec(x) = 1/cos(x)
sec(x) = 1/(2/3)
sec(x) = 3/2
Problem 2:
sinβ = -5/6
cscβ = ?
cscβ = 1/sinβ
cscβ = 1/(-5/6)
cscβ = -6/5
Problem 3:
secφ = 2
tanφ = √3
sinφ = ?
secφ = 1/cosφ
tanφ = sinφ/cosφ
tanφ = sinφ/cosφ
tanφ = sinφ(1/secφ)
√3 = sinφ(1/2)
2√3 = sinφ
Problem 4:
secθ = 8
tanθ = 3√7
cscθ = ?
secθ = 1/cosθ
tanθ = sinθ/cosθ
cscθ = 1/sinθ
tanθ = sinθ/cosθ
tanθ = sinθ(1/cosθ)
3√7 = sinθsecθ
3√7 = sinθ(8)
(3√7)/8 = sinθ
cscθ = 1/sinθ
cscθ = 1/((3√7)/8)
cscθ = 8/(3√7)
cscθ = (8√7)/21
Problem 5:
sinθ = 2/√5
cosθ = 1/√5
tanθ = ?
tanθ = sinθ/cosθ
tanθ = (2/√5)/(1/√5)
tanθ = (2/√5)(√5)
tanθ = 2

Answer:
B. $5039.58
Step-by-step explanation:
compound interest formula: amount = p(1 + \frac{r}{n})^{nt}
p= principal ($2,300)
r= interest rate as a decimal (4% = 0.04)
n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)
t= time in years (20 years)
new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}
That equation equals $2,739.58 which you add to the principal.
$2,739.58 + $2,300 = $5039.58
