In the mid term test Jesse scored 92%,89% and 90%.What was her main score
Answer:
100%
Step-by-step explanation:
Answer:
90.3%
Step-by-step explanation:
I think you have a typo. I'm pretty sure you meant mean score. To find the mean, we add up all the values and divide by the number of values. Let's add 92, 89, and 90. That gets us 271. Now, let's divide 271 by 3. That gets us 90.3. That means Jesse's mean score is 90.3%.

Line segment AB || line m
Therefore, BC is transversal.
[tex] \therefore m\angle ABC + (m\angle ACB +m\angle A D) = 180\degree[/tex]
[tex] \therefore m\angle ABC + (55\degree + 40\degree) = 180\degree[/tex]
[tex] \therefore m\angle ABC + 95\degree = 180\degree[/tex]
[tex] \therefore m\angle ABC = 180\degree -95\degree [/tex]
[tex] \therefore m\angle ABC = 85\degree [/tex]
A bouncy ball is dropped such that the height of its first bounce is 6.25 feet and each
successive bounce is 80% of the previous bounce's height. What would be the height
of the 11th bounce of the ball?
Answer:
0.67 feet
Step-by-step explanation:
This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%
So, we have:
[tex]T_n = ar^{n-1}[/tex]
In this case:
[tex]r - 80\% = 0.8[/tex]
[tex]n = 11[/tex]
So, we have:
[tex]T_{11} = 6.25 * 0.8^{11-1}[/tex]
[tex]T_{11} = 6.25 * 0.8^{10}[/tex]
[tex]T_{11} = 6.25 * 0.1073741824[/tex]
[tex]T_{11} = 0.67ft[/tex]
Hence, the height of rebound at the 11th time is approximately 0.67

Answer: x=32
Step-by-step explanation:
Because a triangle is 180°, the missing angle in the triangle would be 60°.
Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.

Write the equation of a line that is perpendicular to y=7x−2 and passes through the point (14,8).(1 point) y=7x−90 y=10x−17 y=−17x+1067 y=−17x+10
Answer:
[tex]\huge\boxed{y=-\frac{1}{7}x+ 10}[/tex]
Step-by-step explanation:
In order to find the equation of this line, we need to note two things.
A) The slope of two lines that are perpendicular will be opposite reciprocals (that is, multiplying them gets us -1.)B) We can substitute a point inside an incomplete equation to try and find a missing value.So first, let's find the opposite reciprocal of 7 which will be the slope to this equation.
Reciprocal of 7: [tex]\frac{1}{7}[/tex] Opposite of [tex]\frac{1}{7}[/tex]: [tex]-\frac{1}{7}[/tex]So the slope of this line will be [tex]-\frac{1}{7}[/tex]. The y-intercept will change, and we can substitute what we know into the equation [tex]y=mx+b[/tex].
[tex]y = -\frac{1}{7}x+b[/tex]
Now, we can substitute a point on the graph (14, 8) into this equation to find b.
[tex]8 = -\frac{1}{7} \cdot 14 + b[/tex] [tex]8 = -\frac{14}{7} + b[/tex] [tex]8 = -2 + b[/tex] [tex]b = 10[/tex]Now that we know the y-intercept, we can finish off our equation by plugging that in.
[tex]y = -\frac{1}{7}x + 10[/tex]

Step-by-step explanation:
Hey there!
Given;
sec x - tan x . sin x = 1/(sec x).
~ Taking LHS.
= sec x - tan x . sin x
= 1/(cos x) - (sin x/cos x) . sin x { Using formula sec x = 1/cos x and tan x = (sin x/cos x)}
~ Multiply (sin x) and (sin x).
[tex] = \frac{1 - { (\sin(x) )}^{2} }{ \cos(x) } [/tex]
~ Use formula 1-sin²x= cos²x
[tex] = \frac{ {cos}^{2} x}{ \cos(x) } [/tex]
~ Cancel cos x.
= cos x
= 1/sec x { cos x = 1/sec x}
→ RHS proved.

Out of 498 applicants for a job, 187 have over 10 years of experience and 127 have over 10 years of experience and have a graduate degree. Step 1 of 2 : What is the probability that a randomly chosen applicant has a graduate degree, given that they have over 10 years of experience
Answer:
the probability that randomly selected applicants over 10 years of experience is 0.6791
Step-by-step explanation:
The computation of the probability that randomly selected applicants over 10 years of experience is as follows:
Total would be
= 187 have 10 + years experience
Now
P(graduate | 10+) = (graduate and 10+ years experience) ÷ (10 + years of experience)
= 127 ÷ 187
= 0.6791
Hence, the probability that randomly selected applicants over 10 years of experience is 0.6791
Write an equation of the line that passes through (−2,3) and (0,8).
Answer:
[tex]y = \frac{5}{2}x + 8[/tex]
Step-by-step explanation:
(-2 , 3 ) ; (0 , 8)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{8-3}{0-[-2]}\\\\=\frac{5}{0+2}\\\\=\frac{5}{2}[/tex]
m = 5/2 ; (0 , 8)
Equation: y -y1 = m(x -x1)
[tex]y - 8 =\frac{5}{2}(x - 0)\\\\y - 8 =\frac{5}{2}x\\y = \frac{5}{2}x + 8[/tex]

3 There are 5 times as many boys as girls in a school.
Together the school has 810 pupils.
How many boys are there?
Answer:
Number of boys = 675
Step-by-step explanation:
Given that:
There are 5 times as many boys as girls in a school.
Number of pupils in school = 810
Let,
x be the number of girls
y be the number of boys
According to given statement;
x+y=810 Eqn 1
y = 5x Eqn 2
Putting y=5x in the Eqn 1
x+5x=810
6x=810
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{810}{6}\\x=135[/tex]
Putting x=135 in Eqn 2
y = 5(135)
y = 675
Hence,
Number of boys = 675
