Answer:
0.8704
Explanation:
The probability of successfully shooting a basketball is 2/5, so the probability t3/o fail will be equal to:
[tex]P=1-\frac{2}{5}=\frac{3}{5}[/tex]Then, we will calculate the probability of failing the 4 shots. So, we need to multiply 3/5 by itself 4 times.
[tex]P(\text{fail all times) = }\frac{3}{5}\times\frac{3}{5}\times\frac{3}{5}\times\frac{3}{5}=0.1296[/tex]Finally, the probability of her shooting in at least 1 if the complement of the probability to fail all times, so, the answer is:
[tex]P(at\text{ least 1) = 1 - 0.1296 = 0.8704}[/tex]Therefore, the answer is 0.8704
Given is a parallelogram ABCD. Verify each measure is correct. AE = 10EC = 10 DE = 10EB = 10
AE = 10 and EC = 10
1) Let's find out the measure of each section of those diagonals. Since in a parallelogram their diagonals are bisected. So we can write:
2y = y+5 Subtract y from both sides
2y -y = 5
y= 5
x+1 = 3x -13
x-3x = -13 -1
-2x =-14
2x = 14
x = 7
2) As we now know the measure of each half of those diagonals we can write:
AE = 2y
AE = 2(5)
AE = 10
EC = y+5,
EC =10
DE = x +1
DE = 8
EB = 3(7) -13 = 8
3) Hence, the correct measures are AE = 10 and EC = 10

Given:
Some of the tallest crystals in a cave in Mexico are 85 feet tall.
Lin is 6 feet tall.
Number of times = tallest crystals height / lin height.
= 85 feet / 6 feet

ANSWER
10,000
EXPLANATION
Given:
The first-three digits to be 1, 8, 0 out of seven-digit telephone numbers.
Desired outcome:
Total number of possible different telephone numbers
Determine the possibilities of the 4th, 5th, 6th and the 7th digits
The 4th digit has 10 possibilities (i.e: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
The 5th also has 10 possibilities,
likewise the 6th and the 7th digits.
Now, we have:
10 x 10 x 10 x 10 = 10^4 = 10,000
Hence, the number of possible different telephone numbers is 10,000.
A property owner paid $960 for the tiles to cover a 800 sq. ft yard. Then he decided to tile an additional 260 sq. ft. How much will be paid for the additional tiles?
Answer:
$312 will be paid for the addditional tile
Explanation:
Given that the property owner paid $960 for tiles to cover a 800 sq. ft yard
Since he decided to tile an additional 260 sq. ft, to know how much will be paid for the additional tiles, we need to know how much he paid for each of the last set of tiles.
The amount is
960/800 = 1.2
He paid $1.2 per tile.
For 260 sq. ft, he will pay:
$1.2 * 260
= $312

Write an equation to represent the sum modeled in the following number line. H H H -4 -3 -2 -1 0 1 2 3 4
The number line shows numbers graded into three parts each such that each point between numbers represent 0.33 units.
This means the red line moving towards the left is a negative because it falls to the left of point 0, where the division between positive and negative numbers take place.
Hence the red line indicates -3.33
The blue line is movin towards the right which means its a positive value. Note that it begins from -3.33 and ends at -1.33. Hence the blue line is a positive value and it covers two units.
The equation that models this number line can be written out as

What is division ?
In mathematics, division is the process of dividing a given sum into equal pieces. As an illustration, we could divide a group of 20 people into 4 groups of 5, 5 groups of 4, and so on. The opposite of multiplication is division. When you multiply three groups of four to produce twelve, you get four in each group when you split twelve into three equal groups. The basic objective of splitting is to determine how many equal groups are created or how many people are in each group after a fair distribution.
Here the given ,
length of Python = 212 feet
length of Vortex = 210 feet
Here to find the length we need to divide python length by vortex length
=> [tex]\frac{212}{210}[/tex]
=> 1.01 times.
Therefore Python is 1.01 times as long as Vortex.

Given the experimental results of spinning the spinner:
Yellow: 212
Red: 144

The sum of times = 500
a) from Martina's results, compute the experimental probability of landing on red.
So, the answer will be probability = 144/500 = 0.288
b) assuming that the spinner is fair, compute the theoretical probability of landing on red.
As shown: the spinner has 10 equally sized slices.

So, the probability of red = 3/10 = 0.3
c) assuming that the spinner is fair, choose the statement below that is true.
The true statement will be:
1. the larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability.
