Answer:
D. 0.74.
Step-by-step explanation:
It is a BINOMIAL trial, which means that there are only two outcomes: either success, or failure.
So, if the probability of success is 0.26, the probability of failure will be 1 - 0.26 = 0.74.

Mr. A runs 500 meters in 1 minute, Mr. R runs 450 meters in 50 seconds, Mr. M runs 600 meters in 70 seconds and Mr. K runs 400 meters in 45 seconds. Based on these times, which runner would win a 100 meter race?
Step-by-step explanation:
1minute=60seconds
500 meters=60
100 meters=x
cross multiply
500×x=100×60
500x=6000
x=12
Mr. A will use 12seconds
450meters=70
100=a
cross multiply
450×a=100×70
450a=7000
divide both sides by 450
400=45
100=n
cross multiply
400×n=100×45
400n=4500
divide both sides by 400
divide and get your answer

Your baseball team has won 6 games and lost 4 games. If the team
does not lose any more games, how many games must the team win
to have a win : loss ratio of 2:1? Explain your answer.
Answer:
two games must be won by the team
Step-by-step explanation:
Let the no. of games played by x, since team
does not lose any more games.
Then total game won = 6+x
total game lost = 4
win: loss = 6+x : 4
given ratio of win and loss = 2:1
6+x : 4 = 2: 1
6+x = 8
=> x = 8-6 = 2
Thus, two games must be won by the team
then total win will be = 6+2 = 8
and loss = 4
ration of win : loss = 8:4 = 2:1

Answer:
m<PQT= 94°
Step-by-step explanation:
If line QS bisect <PQR
m<PQS = m < SQR
7x-6= 4x+15
7x-4x= 15+6
3x= 21
X= 21/3
X= 7
m<PQS= 7x-6
m<PQS= 7(7)-6
m<PQS= 49-6
m<PQS= 43°
m<PQS= m<SQR
<mSQR=43°
m<PQR= m<PQS + m < SQR
m<PQR=43+43
m<PQR= 86°
BUT
m<PQR= m<TQW
m<PQT= m<RQW
m<PQR+m<TQW +m<PQT+ m<RQW
= 360°
Let m<TQW= x
86+86+x+x= 360
2x+172= 360
2x= 188
X= 94°
m<PQT= 94°

A class has 25 students in it. 4 students drop the class. What is a reasonable estimate for the percentage of students that dropped?
Answer:
16% drop
Step-by-step explanation:
4/25 drop
Multiply by 4/4
16/100
16% drop
Answer:
16%
Step-by-step explanation:
SInce 4 students left the class, and there are 25 students, let's make it a fraction.
4/25.
As it is asking for a percentage though we could simply convert our fraction to a percentage.
Simply divide the numerator (4) by the denominator (25).
This gives us 0.16.
Which is 16%.
determine the equation for the quadratic relationship graphed below.
Answer:
[tex]\large \boxed{\sf \bf \ \ y=3x^2-6x-1 \ \ }[/tex]
Step-by-step explanation:
Hello, please consider the following.
We can read from the graph that the vertex is (1,-4) , it means that the equation is, a being a real number.
[tex]y=a(x-1)^2-4[/tex]
And the point (0,-1) is on the graph so we can write.
[tex]a\cdot 1^2-4=-1 \\\\a-4+4=-1+4\\\\a = 3[/tex]
So the equation is.
[tex]y=3(x-1)^2-4\\\\=3(x^2-2x+1)-4\\\\=3x^2-6x+3-4\\\\=3x^2-6x-1\\\\=\boxed{3}x^2\boxed{-6}x\boxed{-1}[/tex]
Hope this helps.

What are the solutions of x2 + 20 = 12x.
Answer:
x₁ = 2
x₂ = 10
Step-by-step explanation:
x² + 20 = 12x
x² - 12x + 20 = 0
(x-2)(x-10) = 0
then:
x₁ = 2
x₂ = 10
Check:
x₁
2² + 20 = 12*2
3 + 20 = 24
x₂
10² + 20 = 12*10
100 + 20 = 120

The marked price of a mobile is 25% above its cost price, When it is sold at a gain of
10%, the profit amounts to Rs 725. Find the marked price of the mobile.
Answer:
The marked price is Rs 823.86
Step-by-step explanation:
Let the cost price be Rs x. The marked price of the mobile is 25% above its cost price. Therefore:
The marked price = x + 25%(x) = 1 + 0.25x = 1.25x
When the mobile phone is sold at a gain of 10%. the profit is Rs 725, to find the cost price we use:
x + 10%(x) = 725
x + 0.1(x) = 725
1.1x = 725
x = 725/1.1 = 659.09
The cost price is Rs 659.09. Therefore the marked price is given as:
Marked price = 1.25x = 1.25(659.09) = 823.86
The marked price is Rs 823.86
Find the value of x to the nearest tenth.
Answer:
Step-by-step explanation:
Using Pythagoreus Theorem
In the smaller rectangle
2²+4² = h²
20 = h²
h = √20
h = 2√5
Therefore two sides of the rectangle will 2√5
No using pythagoreus theorem in the bigger triangle
x² + (2√5)² = 9²
x² = 9² - (2√5)²
x² = 81 - 20
x = √61
x = 7.8102496759
When rounded off to nearest tenth the hundreth digit is in 0-5 range
x = 7.81

Please Help Find the indicated side of the right triangle
Answer:
3 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 60 = x/3
3 tan 60 = x
3 sqrt(3) = x
Answer:
x = 3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{3}{x}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

Answer:
y=-4x+16
Step-by-step explanation:
Okay, so a perpendicular line has an opposite reciprocal slope.
The slope for the first line is x/4, but I like to write it as 1/4x, since it's easier to look at.
The opposite reciprocal for 1/4x is -4x
So far, we have y=-4x+ [ ]
To find the remaining b value, we can use the given point intersection.
plug in the x and y values given (4, -1) and solve for b.
The equation for the perpendicular line is y=-4x+16

find y=? when x=7.
given that y varies directly with x.
y = kx
Where k is the constant of proportionality
k= y/x
k= (1/4)÷ 5

Complete the conditional statement. If 2 > -a, then _____.
Well, in this case we can take a as the protagonist.
We can, for example, take the a in the first member of the disequation, the 2 in the second one, changing the signs
so
+ 2 > - a
a > - 2
In fact,
"If 2 > - a, then a > -2."
The sum of first three terms of an arithmetic series is 21. If the sum of the first two terms is subtracted from the third term then it would be 9. find the three terms of the series
Answer:
The terms are - 1, 7 and 15.
Step-by-step explanation:
Let the terms be a-d, a and a+d
ATQ, a-d+a+a+d=21, a=7. a+d-(a+(a-d))=9. d=8. The terms are - 1, 7 and 15.
If the angles a°&b° are complements of each other, then a°+b°= 90° 180° 270° 360°
Answer:
a + b = 90°
Step-by-step explanation:
If sum of two angles are 90°, then the two angles are complementary
Angles that are complements form corners. I've bolded the "co" letters to help remember that complementary angles form a 90 degree corner. Whereas supplementary angles form a straight line (both "supplementary" and "straight" start with "S"). So that's one way to remember the two terms.
Anyways, if a and b are complements of each other, then a+b = 90.
