Answer:
Step-by-step explanation:
To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove
Answer:
20 units
Step-by-step explanation:
This implies that the square can be divided into four equal L-shaped regions. These regions with respect to transformation forms a square.
Perimeter of the square is 40 units. Since a square has equal length of sides, thus each side of the square is 10 units.
Thus, each L-shape region has dimensions; 8 units, 5 units, 5 units and 2 units.
Perimeter of each L-shape region = the addition of the length of each side of the shape
Perimeter of each L-shape region = 8 + 5 + 5 + 2
= 20 units
Answer:
<h2>A. Agree, 4 children is the most typical number of children.</h2>
Step-by-step explanation:
By analysis the problem, we can make our decision by first determining the percent of 3.55 of 4
therefore the percentage can be computed as
=(3.55/4)*100
=0.8875*100
=88.75%
The analysis above it shows that 88.75 percent of the women who give birth to children give birth to 4 children.
This number is very close to a hundred percent hence the statistical claim is "Agree, 4 children is the most typical number of children."
Answer:
The rate of this account corresponds to a increse of 25%.(Option 4)
Step-by-step explanation:
To find out the increase/decrease rate, first we need to re express the exponential term:
V=750*(0.80)^-x
By applying the respectives properties we can express the exponent of the equation as follows:
(0.80)^-x = 1/(0.8^x) = (1^x)/(0.8^x) = (1/0.8)^x = 1.25^x
Then the Kalani's stock investments can be written as:
V=750*1.25^x
Then the above equation can be expressed as:
V=750*(1+0.25)^x
Where 0.25 represents a increment rate of 25%
Solution: We are given:
We need to find the test statistic in order to test the claim that the mean weight of all green candies is equal to 0.8535
We know that the test statistic is:
Therefore, the test statistic is 
Hence the option -1.36 is correct.
