Final answer:
Using the least squares line equation y = −10.2638 + 0.0491x and substituting 748 for x, the number of reported dead birds, we find the expected number of human West Nile virus cases to be approximately 26 when rounded to the nearest whole number.
Explanation:
The question asks to predict the number of human West Nile virus cases based on the number of reported dead birds using a least squares line equation provided. Given the equation y = −10.2638 + 0.0491x and the value x = 748, which represents the number of dead birds, we can substitute x into the equation to calculate y, the expected number of human cases.
The calculation is as follows:
y = −10.2638 + 0.0491 × 748
y = −10.2638 + 36.7268
y = 26.463
After performing the calculation, we round the result to the nearest whole number:
Expected number of human cases = 26
Identify the 7th term of the geometric sequence in which a2 = 324 and a4 = 36
Answer:
4/3
Step-by-step explanation:
a2 = 324 and a4 = 36
second term is 324 and fourth term is 36
[tex]a_n= a_1(r)^{n-1}[/tex]
To get second term, replace n with 2
[tex]a_2= a_1(r)^{2-1}[/tex]
[tex]a_2= a_1(r)[/tex]
replace a2 with 324
[tex]324= a_1(r)[/tex] -----------> equation 1
To get fourth term , replace n with 4
[tex]a_4= a_1(r)^{4-1}[/tex]
[tex]a_4= a_1(r)^3[/tex]
Replace the value
[tex]36= a_1(r)[/tex] -----------> equation 2
divide second equation by first equation
[tex]36= a_1(r)^3[/tex] divide by [tex]324= a_1(r)[/tex]
1/9 = r^2
take square root on both sides
1/3= r
now we find a1
[tex]324= a_1(r)[/tex]
[tex]324= a_1(\frac{1}{3})[/tex]
multiply by 3 on both sides
972= a_1
So a1= 972, r= 1/3
now find out 7 term by replacing 'n' with 7
[tex]a_7= 972(\frac{1}{3})^{7-1}[/tex]
So 7th term is 4/3

The pitch of a roof is its slope. The roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft. Find the pitch of the roof.
The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.
What is Slope?
The slope of line is a measure of its steepness.
Given that;
Vertical distance (rise) = 8 feet
Horizontal distance (running) = 15 feet
Now, To find the pitch (slope) of the roof, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Hence, The pitch (slope) of a roof is given by the formula;
Pitch = V / R
Where:
V is the rising vertical distance of an object.
H is horizontal distance an object runs through.
Hence, Substituting the given parameters into the formula, we have;
Pitch = 8/15
= 0.53
Thus, Pitch (slope) = 0.53
So, The pitch of a roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft is 0.53.

How do you multiply mixed negative number fractions?
what is the limit as x is approaching 0 of the absolute value of x
The restriction of the outright worth of x as x methodologies 0 will be 0. Outright worth guarantees that the result is non-negative, and as x methodologies zero from one or the other side, the outcome stays at 0.
Explanation:The inquiry you're posing relates to the furthest reaches of the outright worth capability as the variable x methodologies are the worth of nothing. In science, explicitly in math, we assess cutoff points to comprehend the way of behaving of capabilities as they approach a specific point.
To track down the breaking point as x methodologies 0 of the outright worth of x, signified as lim x→0 |x|, we want to think about the meaning of outright worth. The outright worth of a number is the non-negative worth of that number regardless of its sign. In this manner, as x methodologies 0 from either the positive or negative side, the outright worth of x will likewise move toward 0.
Consequently, the cutoff is 0, since as x gets increasingly close to nothing, so does the outright worth of x.

The diagram shows a trapezium ABCD in which BC parallel to AD
Answer:
if its the diagram i think then:
f = 6cm
g = 8cm
Step-by-step explanation:
square = 48cm²
triangle = 12cm²
24 / 4 = 6
AD = 6cm
So
BC = 6cm
CD = 48 / 6 = 8cm
CD = 8cm
f = 6cm
g = 8cm
In geometry, a quadrilateral with at least each pair of parallel sides is referred to as a trapezoid. Therefore, the length of BC is 6cm and the length of CD is 8cm.
What is trapezium?In geometry, a quadrilateral with at least each pair of parallel sides is referred to as a trapezoid both Canadian and American English, and perhaps a trapezium in British as well as other forms of English. In Euclidean geometry, a trapezoid is a convex quadrilateral by definition.
The bases of a trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs; if not, the trapezoid is indeed a parallelogram, with 2 sets of bases. A trapezoid without equal-sized sides is called a scalene trapezoid.
area of square = 48cm²
area of triangle = 12cm²
24 / 4 = 6
AD = 6cm
BC = 6cm
CD = 48 / 6 = 8cm
CD = 8cm
f = 6cm
g = 8cm
Therefore, the length of BC is 6cm and the length of CD is 8cm.

Solve: 7b-20=3b+12
you borrow $200 from a friend to help pay for the new laptop computer. You pay your friend $12 per week. Write and solve an inequality to find when you will owe tour friend less than $60.
You will owe your friend less than $60 if you pay them $12 per week for more than 11.67 weeks, which means you'll need to make payments for at least 12 full weeks.
Explanation:To solve the problem of when you will owe your friend less than $60, we need to set up and solve an inequality.
The amount owed after any number of weeks can be represented by the initial debt of $200 minus the total amount paid off, which is $12 times the number of weeks.
If we let x represent the number of weeks, the inequality we need to solve is 200 - 12x < 60.
To solve this inequality, we subtract 200 from both sides, getting -12x < -140.
Then, we divide both sides by -12, remembering to reverse the inequality sign because we are dividing by a negative number, which gives us x > 11.67.
Since we can't pay off part of a week, we would need to pay your friend for at least 12 full weeks to owe less than $60.
Final answer:
To find when you will owe less than $60, set up the inequality 200 - 12w < 60. After simplifying, we see that it will take just over 11.67 weeks, so you will owe less than $60 after making payments for 12 weeks.
Explanation:
To solve the problem at hand, we need to create an inequality to represent the situation where you will owe less than $60 to your friend. Let's denote the amount owed each week with w and the total amount owed with A. You start with an initial debt of $200, and each week you pay off $12. The inequality we are trying to establish is when the total amount owed will be less than $60.
The inequality will be in the form of A - 12w < 60, where A is the initial amount of $200 and w represents the number of weeks. Plugging in $200 for A, we get 200 - 12w < 60.
To solve for w, we'll perform the following steps:
Subtract $200 from both sides to isolate the variable term: -12w < -140.
Since we are dividing by a negative number, remember to flip the inequality sign: w > 140/12.
Simplify the fraction to get the minimum number of weeks: w > 11.67.
You will owe your friend less than $60 after roughly 12 weeks since fractions of a week don't apply in the context of a weekly payment schedule.
