can someone find the length of the spine plss
Answer:
48.2 cm
Step-by-step explanation:
The bottom side of the large triangle has length 78 cm.
The bottom side of the right triangle has length 78 cm/2 = 39 cm.
Now we use the Pythagorean theorem to find the vertical side, the spine.
39² + s² = 62²
s² = 3844 - 1521
s² = 2323
s = 48.2

Find the sum of the first 8 terms of the following series, to the nearest integer.16,20,25
The correct answer is 317.
The sum of the first 8 terms of the series, to the nearest integer is,
⇒ S₈ = 317
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
The series is,
⇒ 16, 20, 25,
Now, We get;
Common ratio = 20 / 16 = 5 / 4
And, 25 / 20 = 5 / 4
Thus, The series is geometric series.
Hence, The sum of the first 8 terms of the series, to the nearest integer is,
⇒ S₈ = 16 ((5/4)⁸ - 1) / (5/4 - 1)
⇒ S₈ = 16 (390625/65,536 - 1) / (1/4)
⇒ S₈ = 16 × 4 (325,089 / 65,536)
⇒ S₈ = 317.46
⇒ S₈ = 317
Thus, The sum of the first 8 terms of the series, to the nearest integer is,
⇒ S₈ = 317

Randall is mapping the area of his town using the map below and placing the town hall at the origin. The shopping mall is three units north of the movie theater. A parking garage is located one unit south of the shopping mall. The movie theater is six units to the east of the town hall. A beauty parlor is reflected across the x-axis from the location of the parking garage.
Locate the shopping mall, movie theater, parking garage, and beauty parlor on the map.
Answer:
Shopping Mall: (-6,3)
Movie Theater: (-6,0)
Parking Garage: (-6,2)
Beauty Parlor: (-6, -2)
Explanation:
The starting point here is the (0,0), or what would be considered according to the reading the "Town Hall".
The shopping mall is a point at the west (left) of the graph. We can know this because during the reading it is specified that the city center is 6 units east of the movie theater, which is only three units south of the mall. This means that the same distance of x between the Shopping Mall and the line y would be the same as the movie theater to the town hall, adding three units of y: (-6, 3)
Knowing this point, the Parking Garage is easier to find since it is just one unit below the mall. (-6, 2). Only the y value changes.
Knowing where the garage is, the reading says 3 units further down is the Movie Theater —3 units to the south of the shopping mall, and 2 in the same direction of the garage, the red point is marke d at (6.0).
The Beauty Parlor is the reflection of the parking garage across the x-axis. To find the reflection of a graph point across the x-axis, the formula is: (x, y) → (x, -y). Hence, the garage point, which we said was (-6, 2), becomes (-6, -2). The -6 (x) remains negative, while the 2 changes its sign.

What is the measure of ∠B?
Triangle A B C with ray A G through point C and angle measures A = 3x, B = 4x, and exterior angle B C G = 10x minus 45.
60∘60 degrees
15∘15 degrees
45∘45 degrees
105∘
Answer:
Solution given:
4x+3x=10x-45[exterior angle is equal to the sum of two opposite interior angle]
45=10x-7x
x=45/3
x=15
now.
<B=4x=4×15=60° is your answer
The required measure of ∠B is 60° for the given triangle.
What is the Exterior Angle?An exterior Angle is defined as an angle produced on the outside of a polygon by extending the sides of the polygon.
According to the shown figure, we have:
The external angle is ∠BCG = 10x - 45.
And, two interior angles as ∠A = 3x, and ∠B = 4x.
As we know that the sum of two opposite interior angles equals the exterior angle.
So, we can be written as follows:
4x + 3x = 10x - 45
45 = 10x - 7x
x = 45/3
x = 15
So, the measure of ∠B is:
∠B = 4x
∠B = 4 × 15
∠B = 60°
Thus, the required measure of ∠B is 60°.

A random sample of 15 college soccer players were selected to investigate the relationship between heart rate and maximal oxygen uptake. The heart rate and maximal oxygen uptake were recorded for each player during a training session. A regression analysis of the data was conducted, where heart rate is the explanatory variable and maximal oxygen uptake is the response variable.
If a 95 percent confidence interval is constructed for the slope of the population regression line, which of the following is a condition that must be checked?
A) The true relationship between heart rate and maximal oxygen uptake is linear.
B) The correlation between heart rate and maximal oxygen uptake is not equal to zero.
C) The confidence interval is not biased.
D) The point (x_,y_) falls on the regression line. The X and Y have a line on top.
E) The slope is not equal to zero.
Answer:
C) The confidence interval is not biased.
Step-by-step explanation:
When a relationship between two variables is observed the confidence interval should not be biased. If the confidence interval is found to be biased then the observed results will be reliable and accurate. Regression analysis of heart rate and maximal oxygen uptake is analyzed and the correlation will not be equal to zero. This means there will be some correlation between the two variables.
The necessary condition that must be checked is: Option B) The correlation between heart rate and maximal oxygen uptake is not equal to zero
What are explanatory and response variables?Explanatory variables are also called independent variables and they explain variations in the response variables. They are not dependent on any directly considered variable in the considered situation.
The response variables are also called dependent variables and their values depend on the values of the explanatory variables.
For this case, it is considered that:
Explanatory variable: Heart rateResponse variable: Maximal oxygen uptakeIt is not specified that regression is linear but specified that there is regression analysis was conducted. Regression is useful only if there is any correlation between two variables.
Thus, the most important condition that must be checked is:
Option B) The correlation between heart rate and maximal oxygen uptake is not equal to zero
(because 0 correlation shows that variables are independent, so no influence of explanatory variable on response variable and they are independently taking up their values compared to each other).
Thus, the necessary condition that must be checked is: Option B) The correlation between heart rate and maximal oxygen uptake is not equal to zero

COULD YOU PLEASE HELP ME ON MY RECENT QUESTION ASAP
Step-by-step explanation:
According to the data released by the Chamber of Commerce of a certain city, the weekly wages of factory workers are normally distributed with a mean of $720 and standard deviation of $40. Find the probability that a worker selected at random from the city makes the following weekly wage. (Round your answers to four decimal places.)
Complete question :
a. Of less than$720?
b. Of more than $840?
c. Between $680 and $760?
Answer:
0.500 ; 0.0013 ; 0.6827
Step-by-step explanation:
Given that :
Mean, μ = 720
Standard deviation, σ = 40
P(Z < x)
x = (x < 720)
Obtain the standardized value of x
P(x < 720) = (x - μ) / σ
P(x < 720) = (720 - 720) / 40
P(x < 720) = 0
P(Z < 0) = 0.5
B.) More than $840
P(x > 840)
P(x > 840) = (x - μ) / σ
P(x > 840) = (840 - 720) / 40
P(x > 840) = 120 / 40 = 3
P(Z > 3) = 0.0013499 (Z probability calculator)
c. Between $680 and $760?
P(760 < x < 680)
P(760 < x < 680) = ((x - μ) / σ) - ((x - μ) / σ)
P(760 < x < 680) = ((760 - 720) / 40) - (680 - 720) / 40)) = P( Z < - 1) - P(Z < - 1)
P(680 < x < 760) = 0.84134 - 0.15866 = 0.68268
Plsssss help me with this angle circle problem what is x
Answer:
x = 3
Step-by-step explanation:
Once again we want to use the relationship stated earlier
Where A * B = C * D
Once again imagine that the segments in the given problem have letters
A = x
B = 12
C = x + 1
D = 9
Now we create an equation using the relationship
12 * x = 9(x+1)
now we solve using basic algebra
step 1 distribute the 9 to the x and the 1
9 * x = 9x
9 * 1 = 9
now we have 12x = 9x + 9
step 2 subtract 9x from each side
12x - 9x = 3x
9x - 9x cancels out
now we have 3x = 9
step 3 divide each side by 3
3x/3=x
9/3=3
we're left with x = 3
Answer:
x = 3 / C. 3

y=
Answer:
y = [tex]\frac{4}{3}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (6, 10) ← 2 points on the line
m = [tex]\frac{10-2}{6-0}[/tex] = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = [tex]\frac{4}{3}[/tex] x + 2 ← equation of line
