The sequence 1, 4, 16, 64, 256 shows the similar graph increasing from left to right. Option a is correct.
Sequence which have similar graph as certain geometric sequence increasing from left to right.
It is type of sequence and series that has common and equal ratio between preceding values in series.
Here,
The only geometric sequence seems from observation having increasing from left to right, that implies the curve is also increasing from left to right is 1, 4, 16, 64, 256, having common ratio of 4 with preceding values.
Thus, the sequence 1, 4, 16, 64, 256 shows the similar graph increasing from left to right.

6. Andre and Clare are discussing triangle ABC that has a right angle at C and a
hypotenuse of length 15 units. Andre thinks the triangle could have legs that are 9 and
12 units long. Clare thinks angle B could be 20 degrees and then side BC would be 14.1
units long. Do you agree with either of them? Explain or show your reasoning.
Answer:
BOTH ARE CORRECT
Step-by-step explanation:
Given that:
Triangle ABC Is right angled ;Angle ABC
Hypotenus = 15
If legs are 9 and 12 units long ;
From Pythagoras :
9² + 12² = hypotenus²
81 + 144 = 225²
2.) if:
B = 20° ; BC = will be
Using :
Cos θ = BC / 15
Cos 20 = BC / 15
BC = Cos 20 * 15
BC = 0.939692 * 15
BC = 14.09
BC = 14.1
The probability of tails of a weighted coin is 0.8. The number of tails is noted each of the 20 times the coin is tossed. If this procedure is repeated 75 times, what type of distribution is simulated?
Answer:
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Step-by-step explanation:
We are given that
The probability of tails of a weighted coin, p=0.8
n=20
We have to find the type of distribution is simulated if this procedure repeated 75 times .
Random variable is a proportion of number of tails therefore, type of distribution is sampling distribution of the sample proportion.
We have n=20 and p=0.8
Hence, we can say that type of distribution is simulated is given by
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Answer:
I chose answer D. A binomial distribution with n=20 and p=0.8, No clue if correct or not

If a Canada savings Bond is worth $6225 after 7 years, and was originally bought for $5000, what was the annual simple interest rate? Answer as a percentage.
[Formulas are,
[I = P, R, T]
[A = P + I]
[A = P(1 + R times T)
Answer:
3.5%
Step-by-step explanation:
Given data
A=$6225
P=$5000
T= 7years
R=???
Simple interest
A=P(1+rt)
substitute
6225=5000(1+7r)
6225=5000+35000r
collect like terms
6225-5000=35000r
1225=35000r
r= 1225/35000
r=0.035
Hence the rate is 0.035*100= 3.5%

Find the length of BC and BE (show work please)
Answer:
BC = 4 cm
BE = 10.39
Step-by-step explanation:
ABCD is an isosceles trapezoid.
Measures of base angles of an isosceles trapezoid are equal.
[tex]\therefore m\angle ABC = m\angle DCB [/tex]
[tex]\because m\angle DCB = 120\degree [/tex]
[tex]\therefore m\angle ABC = 120\degree [/tex]
[tex] m\angle ABE = 120\degree-90\degree [/tex]
[tex] m\angle ABE = 30\degree [/tex]
in triangle ABE,
[tex]\cos 30\degree =\frac{BE}{12}[/tex]
[tex]\frac{\sqrt 3}{2} =\frac{BE}{12}[/tex]
[tex] BE = \frac{\sqrt 3\times 12}{2} [/tex]
[tex] BE =6\sqrt 3\: cm[/tex]
[tex] BE = 10.39 cm[/tex]
[tex]\sin 30\degree =\frac{AE}{12}[/tex]
[tex]\frac{1}{2} =\frac{AE}{12}[/tex]
[tex] AE = \frac{12}{2} [/tex]
[tex] AE =6 \: cm[/tex]
Next, Draw [tex] CF\perp AD [/tex]
FD = AE = 6
EF = 16 - (AE + FD) = 16 - (6+6) = 16-12
EF = 4 cm
BCFE is a rectangle.
Measures of the opposite sides of a rectangle are equal.
Therefore
BC = EF
BC = 4 cm

in the diagram below of triangle C D E,F is a midpoint of C D and G is a midpoint of D E, if F G = 9x -59, C E = 34 - x, what is the measure of C E?
Answer:
Hey, I'm not sure if my assumptions were correct or not because there is no diagram. I assumed the triangle to be equilateral, the two lines are parallel and the height of the triangle is 1.
Step-by-step explanation:
Since the triangle is parallel*, we can just use ratio and proportion.
[tex] \frac{rise}{run} = \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ \frac{1}{34 - x} = \frac{0.5}{9x - 59} \\ 1(9x - 59) = 0.5(34 - x) \\ 9x - 59 = 17 - .5x \\ 9x + 0.5x = 59 + 17 \\ 9.5x = 76 \\ x = \frac{76}{9.5} \\ x = 8[/tex]
Now that we had found the value of x, we will now substitute that to both equations to get the respective distances.
CE = 34 - x = 34 - 8 = 26

What probability expression is equivalent to P( / z / > 1.96)?
Answer:
Please check the explanation.
Step-by-step explanation:
Given
P(Z > 1.96)
To determine
What probability expression is equivalent to P(Z > 1.96)
Suppose Z is a standard normal variable.
Therefore,
P(Z > 1.96) = 1 - P(Z ≤ 1.96)
solving
= 1 - Ф(1.96)
= 1 - 0.9750
= 0.0250
The probability of the expression being equivalent to P(z > 1.96) is calculated as 0.0250.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The given information is P(z > 1.96)
Let z is a standard normal variable. Then we have
P(z > 1.96) = 1 – P(z ≤ 1.96)
P(z > 1.96) = 1 – 0.9750
P(z > 1.96) = 0.0250

For a walk-a-thon a sponsor committed to give you a flat free of $5 plus $2 for every mile m you walk
Answer:
$45
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW;
For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?
$5 was given for participants of the walk-a-thon.
$2 was given for every miles won
Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y
The Total amount that can be given
= (5 + 2y)
Where "y" is the miles value
Then, if you walk for 20 miles, The Total amount that can be given
= 5 + 2(20)
= 5+ 40

Enter an algebraic equation for the word sentence. Use x as your variable. A number increased by 6.8 is 8.9.
Answer:
x + 6.8 = 8.9
Step-by-step explanation:
First let's break this sentence down into parts.
A number increased by 6.8 is 8.9.
"A number" - This value is unknown, therefore we will represent it with x.
"increased by" - This signifies that we will be adding.
"is" - This represents the equal sign (=)
Now let's put these together.
x + 6.8 = 8.9
This is your expression.

A coach of a baseball team orders hats for the players on his team. Each hat costs $9.95. The shipping charge for the entire order is $5.00. The total cost of the coach's order is less than $125.00. What inequality can be used to determine the greatest number of hats, h, the coach orders
Answer: 11
Step-by-step explanation:
Based on the information that have been given in the question, we can use the information to form an inequality which goes thus:
5 + 9.95h < 125
9.95h < 125 - 5
9.95h < 120
h < 120/9.95
h < 12.06
h < 12
Therefore since h is less than 12, the greatest number of hat that can be ordered will be 11.

Answer: 13.64%
Step-by-step explanation:
Alyssa estimates that the gym can hold 660 students even though it can hold 750.
Her percent error is calculated by:
= (Actual seats - Estimated seats) / Estimated seats
= (750 - 660) / 660
= 90 / 660
= 0.1364
