math Finding the root (30points!!!!!)
Answers
Answer:
p = [tex]\frac{12}{7}[/tex]
Step-by-step explanation:
let the root be α then the other root is 3α
The sum of the roots of a quadratic equation is
α + 3α = - [tex]\frac{b}{a}[/tex] = - [tex]\frac{-8}{7}[/tex] = [tex]\frac{8}{7}[/tex]
Thus 4α = [tex]\frac{8}{7}[/tex] ( divide both sides by 4 )
α = [tex]\frac{2}{7}[/tex]
The product of the roots of a quadratic equation are
α × 3α = [tex]\frac{c}{a}[/tex] = [tex]\frac{p}{7}[/tex], that is
3α² = [tex]\frac{p}{7}[/tex] ← substitute value of α
3 × ([tex]\frac{2}{7}[/tex] )² = [tex]\frac{p}{7}[/tex]
3 × [tex]\frac{4}{49}[/tex] = [tex]\frac{p}{7}[/tex]
[tex]\frac{12}{49}[/tex] = [tex]\frac{p}{7}[/tex] ( cross- multiply )
49p = 84 ( divide both sides by 49 )
p = [tex]\frac{84}{49}[/tex] = [tex]\frac{12}{7}[/tex]

Answers
Answer:
x=5
Step-by-step explanation:
hope this is correct have a wonderful day! <3
Answer:
x=5
Step-by-step explanation:
10+1.5x=3.5x
Subtract 3.5x from both sides.
10+1.5x−3.5x=0
Combine 1.5x and −3.5x to get −2x.
10−2x=0
Subtract 10 from both sides. Anything subtracted from zero gives its negation.
−2x=−10
Divide both sides by −2.
x= −2 /−10
Divide −10 by −2 to get 5.

Which triangles are similar ?
Answers
Answer: ΔABC ≅ ΔADB
Step-by-step explanation:
In order to be similar, they must have the same angles.
ΔABC ΔADB ΔDBC
∠A = 180 - (2a + b) ∠A = 180 - (2a + b) ∠D = 180 - (a + b)
∠B = a + b ∠D = a + b ∠B = b
∠C = a ∠B = a ∠C = a
ΔABC and ΔADB have the same angles so they are similar.
Which distribution is most nearly appropriate to describe_______the number of fatalities in Texas in a given year due to poisonous snakebites.
Answers
Answer: Poisson distribution
Step-by-step explanation:
The Poisson distribution simply measures the chance for an event occuring based on a particular period of time. It is typically useful for finding the probability of events that have low probabilities of occuring.
Therefore, the distribution that will be ideal in knowing the number of fatalities in Texas in a given year due to poisonous snakebites is the poisson distribution.

A rectangular lawn has a perimeter of 15.8 meters and the length is 3.1 meters longer than the width. What are the dimensions of the lawn? If the width of the fixture is w meters, find w to one decimal place.
Answers
Answer:
w is 4.8 meters
Step-by-step explanation:
-perimeter is 15.8 m so all the sides of the rectangle adds up to 15.8.
- a rectangle has 2 sets of equal sides.
-first, do 3.1 times 2 to get the length of the first set of equal sides. This equals to 6.2.
-now 15.8 - 6.2 = 9.6 meters
- 9.6 divided by 2 to find the width, as well as the measurements of the second set of equal sides.
the width, w, is 4.8 meters.
2W + 2W + 6.2 = 15.8
4W + 6.2 = 15.8
4W = 9.6
W = 2.4
Perimeter
2.4 + 2.4 + (2.4 + 3.1) + (2.4 + 3.1) = 15.8

What variables are categorical, and which are quantitative?

To start with ; Categorical and quantitative variables differ most notably in the fact that, quantitative variables deals with numbers, measurements or calculated mathematical values of certain attribute in a measured species or sample.

Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]
Option A is correct.
Step-by-step explanation:
We need to solve the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex]
We need to divide both the terms.
Solving:
[tex]2\frac{3}{5}\div \frac{2}{3}[/tex]
First we will convert the mixed fraction into improper one
[tex]\frac{13}{5}\div \frac{2}{3}[/tex]
Now, we will convert division sign into multiplication, the term 2/3 is reciprocated
[tex]\frac{13}{5}\times \frac{3}{2}[/tex]
Now, multiply numerator with numerator and denominator with denominator
[tex]\frac{39}{10}[/tex]
Now, we will convert into mixed fraction
[tex]3\frac{9}{10}[/tex]
So, Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]
Option A is correct.

Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
