The solution is, the required probability is 15/36 .
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
from the given table, we get,
total number of sample space is 6 x6 = 36.
now, we get, that, the number of getting sum less than 7 is 15
we have,
probability = no. of the event/ no. of total outcome
= 15/36
we get this,
because if you solve everything below 7 that would give you 15 problems and there is 36 outcomes bc 6 x6 is 36.
Hence, The solution is, the required probability is 15/36 .

Find the first two terms of the geometric sequence.
Answer:
125, 100, 80,64,51.2,40.96...
Step-by-step explanation:
y=[tex]\frac{4}{5}[/tex]x
So let's work backwards!
[tex]\frac{5}{4}[/tex](80)
=100
Then...
[tex]\frac{5}{4}[/tex](100)
=125
Hope this helps! :D
Answer:
125, 100
Step-by-step explanation:
Perhaps the terms of your series are supposed to be ...
__, __, 80, 64, 51.2, 40.96, ...
The common ratio is 64/80 = 0.8, so the recursive relation is ...
t[n] = 0.8×t[n-1]
__
Solving for the previous term, we find ...
t[n]/0.8 = t[n-1] . . . . . . divide by 0.8
or ...
t[n-1] = 1.25×t[n] . . . . . rearrange
Then the term previous to 80 is 1.25×80 = 100.
And the term previous to 100 is 1.25×100 = 125.
The first two terms of the geometric sequence are 125 and 100.

Answer:
16,20
Step-by-step explanation:
As shown, you add four by each.
4+4=8
8+4=12
So, 12+4=16
16+4=20
Answer:
16 and 20
Step-by-step explanation:
In the arithmetic squence, we can tell that 4 is being added to each term.
Thus, we obtain the following rule:
4x [Where "x" is the xth term]To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.
Determining the 4th term of the sequence:
⇒ 4x
⇒ 4(4)
⇒ 16
Determining the 5th term of the sequence:
⇒ 4x
⇒ 4(5)
⇒ 20
Thus, the next two terms are 16 and 20.

What's Ali's average speed on her walk to school if she walks halfway at 2mph and runs the rest of the way at 7mph?
Answer:
s = 28/9
Step-by-step explanation:
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9
The average speed is 28/9.
What is Average speed?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
Example
Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.
To find the average speed we need the total distance and the total time.
Total distance covered by Sam = 200Km + 160 km = 360 km
Total time taken by Sam = 4 hour + 4 hour = 8 hour
Average Speed = Total distance covered ÷ Total time taken
Average Speed = 360 ÷ 8 = 45km/hr
The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:
Average Speed Formula:
Average Speed = Total distance covered ÷ Total time taken
Given:
halfway at 2mph and runs the rest of the way at 7mph
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9 mph

Gina says that she can find the length of the diagonal, c, of the rectangular prism by using the Pythagorean theorem twice.
Drag equations and pictures into the table below to show her work.
Answer:
[tex]\sqrt{149\\ \\[/tex]
However, that's the length of "c" and you're looking to drag it in. So,o you drag in 10^2+7^2=a^2.
Then, as shown by the first picture attatched, you can drag in the one with "c" and "a" with the five shown.
Step-by-step explanation:
To find "c" the diagonal, as explained, you need to use the theorem twice. You can first use it by finding "a", as you already have "b". To find a, you do 10^2+7^2=a^2, the hypotenuse.
100+49=149.
So, a is root 149.
a^2+b^2=c^2 so
149+25=174
a) The length of a, a² = 10² + 7²
b) The fourth Figure will be Drag in Last column.
What is Pythagoras Theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
As From the Figure, a² = 10² + 7²
a² = 100 + 49
a² = 149
a= √149
To find c the diagonal,
a² = 10²+ 7²
a² = 149
a = √149
Now, a²+b²=c²
The fourth Figure will be Drag in Last column.

PART A
If 4 pounds = 10 dollars...
4/2 = 2
10/2 = 5
So for 2 pounds, it would cost $5.00
Now for the 1 pound one
4/1 = 4
10/4 = 2.5
For the 1 pound one, it would cost $2.50
PART B
We know that 4 pounds = 10 bucks
Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb
Now for the last blank...
Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb
