y=1x^(2)+10x+22 line of symmetry
Answer:
x = -5
Step-by-step explanation:
We can use the below formula to find the line of symmetry.
( x - a )² + b
Here,
line of symmetry = +a
Vertex = +b
And now let us take a look at the given equation.
y = x² + 10x + 22
To find the line of symmetry from the given equation we have to make the given equation as the given formula.
Let us use the completing square method for that.
y = x² + 10x + 22
Put zero instead of y.
x² + 10x + 22 = 0
x² + 10x = -22
x² + 10x + 25 = -22 + 25
( x + 5 )² = 3
( x + 5 )² -3 = 0
Therefore,
line of symmetry of the line is = -5
∴ x = -5

Kenneth has a bird feeder which gets visited by an average of 15 birds every 2 hours during daylight hours. What is the
probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours? (Round your
answer to three decimal places.)
Using the Poisson distribution, it is found that there is a 0.507 = 50.7% probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successese = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval.Considering the average of 15 birds every 2 hours during daylight hours, the mean for a 45-minute period is given by:
[tex]\mu = 15 \times \frac{45}{120} = 5.625[/tex]
The probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours is given by:
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
[tex]P(X = 0) = \frac{e^{-5.625}(5.625)^{0}}{(0)!} = 0.004[/tex]
[tex]P(X = 1) = \frac{e^{-5.625}(5.625)^{1}}{(1)!} = 0.02[/tex]
[tex]P(X = 2) = \frac{e^{-5.625}(5.625)^{2}}{(2)!} = 0.057[/tex]
[tex]P(X = 3) = \frac{e^{-5.625}(5.625)^{3}}{(3)!} = 0.107[/tex]
[tex]P(X = 4) = \frac{e^{-5.625}(5.625)^{4}}{(4)!} = 0.150[/tex]
[tex]P(X = 5) = \frac{e^{-5.625}(5.625)^{5}}{(5)!} = 0.169[/tex]
Then:
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.004 + 0.02 + 0.057 + 0.107 + 0.15 + 0.169 = 0.507[/tex]
0.507 = 50.7% probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours.

The perimeter of the triangle ABC is 15.Two altitudes of a triangle have lengths $12$ and $14$. What is the longest possible integer length of the third altitude
The longest possible altitude of the third altitude (if it is a positive integer) is 83.
According to statement
Let h is the length of third altitude
Let a, b, and c be the sides corresponding to the altitudes of length 12, 14, and h.
From Area of triangle
A = 1/2*B*H
Substitute the values in it
A = 1/2*a*12
a = 2A / 12 -(1)
Then
A = 1/2*b*14
b = 2A / 14 -(2)
Then
A = 1/2*c*h
c = 2A / h -(3)
Now, we will use the triangle inequalities:
a < b+c2A/12 < 2A/14 + 2A/h
Solve it and get
h<84
b < a+c2A/14 < 2A/12 + 2A/h
Solve it and get
h > -84
c < a+b2A/h < 2A/12 + 2A/14
Solve it and get
h > 6.46
From all the three inequalities we get:
6.46<h<84

An arithmetic sequence has this recursive formula:
a₁ = 5
an = an-1-4
What is the explicit formula for this sequence?
Answer:
[tex]a_n = 5 + (n-1)(-4)[/tex]
Step-by-step explanation:
So the explicit formula is generally defined as [tex]a_n = a_1 + d(n-1)[/tex]. where d is essentially the "slope", basically how much it's changing from term to term. anyways if you look at the recursive formula you'll notice it's taking the previous term and subtracting 4. This is what d is going to be, -4 and since a_1 is given you plug that in as well. This gives you the equation
[tex]a_n = 5 -4(n-1)[/tex] which can also be written as [tex]a_n = 5 + (n-1)(-4)[/tex]

Martin used 15 gallons to cement to lay sidewalk 50 feet in length. how many gallons of cement were used per foot
Answer:
0.3 gallon
Step-by-step explanation:
To do this problem, we must divide the amount of cement by the number of feet to see how much cement he used for each foot.
15/50 = 0.3 gallon
Answer:
0.3 gallons per foot
Step-by-step explanation:
We know that he used 15 gallons of cement for 50 feet.
We want to find the amount per foot or the amount per each 1 foot.
So we have to divide the 15 gallons by the 50 feet.
15 / 50 = 0.3 gallons per foot.

The number of possible passwords is 26^4 * 10^4.
We will make 4 picks from each category (letters and numbers).
We can duplicate them (i.e., pick each character more than once.)
so, for your 4 picks from the letters, you'll have
26 * 26 * 26 * 26 = 26^4 possible selections.
For each of these, you'll have 4 picks from the digits. Similar reasoning, this works out to

Monogram Masters advertises on its website that 92% of customer orders are received within five working days. They performed an audit from a random sample
of 200 of the 3,000 orders that month and it shows 175 orders were received on time.
Part A: Can we use a normal approximation? Explain. (5 points)
Part B: If Monogram Masters customers really receive 92% of its orders within five working days, what is the probability that the proportion in the random sample
of 200 orders is the same as the proportion found in the audit sample or less? (5 points)
Considering the problem described, we have that:
a) The normal distribution can be used, as both [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].
b) There is a 0.0132 = 1.32% probability that proportion in the random sample of 200 orders is the same as the proportion found in the audit sample or less.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].The parameters of the binomial distribution are:
n = 2000, p = 0.92.
Hence:
np = 200 x 0.92 = 184.n(1-p) = 200 x 0.08 = 16.Since both [tex]np \geq 10, n(1 - p) \geq 10[/tex], a normal approximation can be used. The mean and the standard deviation of the approximation are given as follows:
[tex]\mu = np = 200 \times 0.92 = 184[/tex].[tex]\sigma = \sqrt{np(1 - p)} = \sqrt{200 \times 0.92 \times 0.08} = 3.8367[/tex]The probability that proportion in the random sample of 200 orders is the same as the proportion found in the audit sample or less, using continuity correction, is P(X < 175.5), which is the p-value of Z when X = 175.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{175.5 - 184}{3.8367}[/tex]
Z = -2.22.
Z = -2.22 has a p-value of 0.0132.
0.0132 = 1.32% probability that proportion in the random sample of 200 orders is the same as the proportion found in the audit sample or less.

the two triangles are congruent
b.
the two triangles are similar by SAS
c.
the two triangles are similar by SSS
d.
the two triangles are not similar
Answer:
b) The two triangles are similar by SAS
Step-by-step explanation:
From the diagram below, we can tell that
b. the two triangles are similar by SASWhat is SAS similarity?SAS similarity (Side-Angle-Side similarity) is a criterion used to determine whether two triangles are similar.
It states that if two sides of one triangle are proportional to two sides of another triangle, and the included angles between these sides are congruent, then the two triangles are similar.
In other words, if in two triangles, the ratio of the lengths of corresponding sides is equal, and the included angles between these sides are congruent, then the two triangles are considered similar.
The corresponding angles are congruent and the sides are in proportion
