which function represents the relationship between x and y when y=16/5 and x=20
Answer:
y = (4/25)x
Step-by-step explanation:
We are given;
y = 16/5 and x = 20
Now if y varies directly with x, then we can say;
y = mx
Where m is constant of proportionality
This means that;
16/5 = 20m
Divide both sides by 20 to get;
(16/5) × 1/20 = m
16/100 = m
m = 4/25
Thus,the equation is:
y = (4/25)x
The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. If there are 461 households in the community, about how many of them have electric bills less than $200?
A. 45
B. 21
C. 95
D. 81
95 households have electricity bills of less than $200. Option C is correct.
Given that,
The monthly electric bills in a certain community are normally distributed, with a mean of $245 and a standard distribution of $55. There are 461 households in the community, how many of them have electric bills less than $200 is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
probability for the number of households has electric bills less than $200.
x = 200 , μ = 245 ; σ = 55
Now,
Probability,
z (p < 200) = [tex]\frac{X -\mu}{\sigma}[/tex]
z (p < 200) = (200 - 245)/55
= --45/5
= -0.818181
p < 200 = 0.206 (from z table)
Now, the number of households that has electricity bill less than $200,
= 461 * 0.206
= 94.966
≈ 95
Thus, 95 number of household have electricity bills of less than $200. Option C is correct.

Given the points a ( -2,4 ) and b(7,-2) find the coordinates of the point p on the directed like segment ab that partitions ab in the ratio 1:2
9514 1404 393
Answer:
p = (1, 2)
Step-by-step explanation:
We want ...
(p -a)/(b -p) = 1/2
2(p -a) = b -p . . . . . cross multiply
3p = b +2a . . . .. . . rearrange
p = (b +2a)/3
p = ((7, -2) +2(-2, 4))/3 = (7 -4, -2 +8)/3 = (3, 6)/3
p = (1, 2)

Write an equation to describe this situation using decimals. “Tessa bought x pounds of almonds. Lark (y) bought more than that”. PLEASE HELP!
Answer:
y = 1.6x
Step-by-step explanation:
y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

If xy =1 show that dy/dx=-1/x²
If xy = 1, then differentiating both sides with respect to x gives
x dy/dx + y = 0
(use the product rule)
Solve for dy/dx :
dy/dx = -y/x
Solve the starting equation for y and substitute that into the derivative.
xy = 1 → y = 1/x
→ dy/dx = -(1/x)/x = -1/x²

Emma got 90% of the questions on her history test correct if she answered 27 questions correctly, how many questions did Emma get wrong?
There were (A) questions on the test so she got (B) questions wrong
Answer:
There were 30 questions on the test so she got 3 questions wrong.
Step-by-step explanation:
Given that:
Correct answers by Emma = 27
Percentage of correct answers = 90%
Let,
x be the total number of questions on test
90% of x = 27
[tex]\frac{90}{100}x=27[/tex]
[tex]0.9x=27[/tex]
Dividing both sides by 0.9
[tex]\frac{0.9x}{0.9}=\frac{27}{0.9}\\x=30[/tex]
There were 30 questions on the test.
Wrong answers = Total questions - Correct answers
Wrong answers = 30-27 = 3
Hence,
There were 30 questions on the test so she got 3 questions wrong.
Assume that last year in a particular state with 700000 children there were 1205 children out of 32600 in a random sample who were diagnosed with Autism Spectrum Disorder. Nationally, 1 out of 88 children are diagnosed with ASD. Is there sufficient data to show that the incident rate of ASD is higher in that state than nationally
Answer:
We accept Hₐ there is enough evidence to claim that the incidence of ASD is bigger in this state than it is nationally
Step-by-step explanation:
The population follows a binomial distribution, and the fact that
p₀ = 1205/32600 = 0,03696 and then q₀ = 1-0,03696 = 0,9630
And both
p₀*n = 0,03696*32600 = 1205 > 10
q₀*n = 31395 > 10
The binomial distribution can be approximate to a Normal Distribution, then we need to develop a one tail test ( to the right) to evaluate if the claim " There is sufficient data to show that the incident rate is higher in the mentioned state than the national one.
Therefore:
Hypothesis Test H₀ ⇒ p₀ = p
Alternative Hypothesis Hₐ ⇒ p₀ > p
p is the population proportion mean
p = 1/88 = 0,011
We must test having a very wide Confidence Interval since the matter we are trying is public health then we choose CI = 95 %
CI = 95 % α = 5 % α = 0,05
Critical value for 0,05 is from z-table z(c) = 1,64
We compute z(s)
z(s) =( p₀ - p )/ √ p₀*q₀/n
z(s) = 0,03696 - 0,011 / √ (0,03696*0,9630)/ 32600
z(s) = 0,02596* 180,55/ √ 0,0356
z(s) = 4,687 / 0,189
z(s) = 24,9
Comparing z(s) and z(c) 24,9 > 1, 64
z(s) is out of the acceptance region and we have to reject H₀
We accept Hₐ there is enough evidence to claim that the incidence of ASD is bigger in this state than it is nationally
What are 1/2 and 2/4 as a decimal?
Answer:
0.50 or 0.5

Three machines are used to produce nails. the table displays the total number of nails produced by the three machines over different lengths of time
Answer:
Step-by-step explanation
they answer would be a whole number because you are multiplying by one thousand
Using the principle of proportionality, the number of nails that will be produced by 1 machine in 1 hour is [tex] 21 \frac{3}{5} \: thousand [/tex]
Let :
Number of machines = mNumber of nails produced = nTime taken = tUsing Principle of variation :
Number of machines α nails produced α 1/time[tex] m = \frac{kn}{t} [/tex] ; where k = constant of proportionalityUsing a row from the table :
t = 15 ; n = 81/5
3 = (81/5)k / 15
Cross multiply :
3 × 15 = (81/5)k
45 = (81/5)k
Divide both sides by (81/5) to isolate k
(45 ÷ 81/5) = k
k = (45 × 5/81) = 25/9 = 2.7777
Substituting the value of k into the expression:
[tex] m = \frac{\frac{25}{9}n}{t} [/tex]
We can use the expression to obtain, the value of n ; when m = 1 and t = (1 hour = 60 minutes)
[tex] 1 = \frac{\frac{25}{9}n}{60} [/tex]
[tex] 60 = \frac{{25}{9}}{n}[/tex]
Divide both sides by 25/9 to isolate n
[tex] 60 \times \frac{9}{25} = n [/tex]
[tex] n = \frac{540}{25} = 21 \frac{3}{5} \: thousand \: nails [/tex]

Answer:
The complete table will be:
x y
1 5
0.8 4
0.4 2
Step-by-step explanation:
Given rule is:
y = 5x
In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.
[tex]\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}[/tex]
Putting y = 5
[tex]x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1[/tex]
Putting y = 4
[tex]x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8[/tex]
Putting y = 2
[tex]x = \frac{2}{5}\\x = 0.4[/tex]
Hence,
The complete table will be:
x y
1 5
0.8 4
0.4 2
