Add All The Numbers (Which Gives You 19.43) Then Divide By Four Because There Are Four Numbers That Were Added Together. The Average Is 4.8575.
Answer:
30 years
Step-by-step explanation:
Forming Algebraic expressions and solving them to find the age.
Ratio of age of mother and daughter = 5 : 3
Age of mother = 5x
Age of daughter = 3x
It is given that mother's age is 50 years.
⇒ 5x = 50
Divide both sides by 5.
x = 50÷5
x = 10
Daughter's age = 3x
= 3*10
= 30 years
A. Similar triangles have equal angles even though they're not the same size that was similar means So then
X^2-5x=4x+36
X^2-5x-4x-36=0
X^2-9x-36=0
(X-12)(x(+3)
X=12. X=3
Angle C and angle F are equal
So 4(12)-5=43
Answer:
The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers. We can convert a point slope equation into standard form by moving the variables to the left side of the equation.
Step-by-step explanation:
We can find critical value by using t - table.
For using t - table we need degree of freedom and alpha either for two tailed test or one tailed test.
We can determine degree of freedom by subtracting sample size from one.
So in given question sample size is 23. So we can say degree of freedom(df) for sample size 23 is
df = 23 - 1= 22
Now we have to go on row for degree of freedom 22.
After that we need to find alpha either for two tailed test or one tailedl test.
Confidence level is 99%. We can convert it into decimal as 0.99.
So alpha for two tailed test is 100 - 0.99 = 0.01
Alpha for one tailed test is 0.01/2 = 0.005.
So we will go on column for 0.01 for two tailed test alpha or 0.005 for one tailed test alpha.
SO the critical value 22 degree of freedom and 0.01 two tailed alpha is 2.819 from t - table.
