The point slope form is
y-y1=m(x-x1)
where
m=slope
and you are given a point (x1,y1)

we are iven that slope=2
and a poin is (3,10)
3=x1
10=y1
y-10=2(x-3)

the answer is
y-10=2(x-3)

Answer:

a) 0.9078

b) 0.9832

c) T = 2.9867

Step-by-step explanation:

Given:-

T ~ N (2.7 , 0.8 )

Find:

Find the probability that the tip resistance will fall between 1.3 and 4.0 MPa.

Find the probability that the tip resistance will exceed 1.0 MPa.

Find a value of tip resistance, T, such that 36% of all soil samples have tip resistance values that exceed T

Solution:

a) To find the P ( 1.3 < x < 4.0 ) we will first compute the z-score values:

P (1.3 < x < 4.0 ) = P ( (1.3 - 2.7)/0.8 < Z < (4.0 - 2.7)/0.8)

P (1.3 < x < 4.0 ) = P ( -1.75 < Z < 1.625)

- Using the Z-table values we can evaluate the probability:

P (1.3 < x < 4.0 ) = P ( -1.75 < Z < 1.625) = 0.9078

b) To find the P ( x > 1 ) we will first compute the z-score values:

P ( x > 1.0 ) = P ( Z > (1.0 - 2.7)/0.8)

P ( x > 1.0 ) = P ( Z > -2.125)

- Using the Z-table values we can evaluate the probability:

P ( x > 1.0 ) = P ( Z > -2.125) = 0.9832

c) To find the P ( x > T ) we will first compute the z-score values:

P ( x > T ) = P ( Z > (T - 2.7)/0.8) = 0.36

- We will search for the z value with the condition above from Z-table.

P ( Z > (T - 2.7)/0.8) = 0.36, Z = 0.358375

- Hence, we calculate for T:

T = 0.358375*0.8 + 2.7

T = 2.9867

Fifteen less than twice a number is 21. What is the missing number? |

Vikentia [17]

Answer:

2y - 15

Step-by-step explanation:

well 15 LESS than TWICE a number. okay so let’s start off by making a variable for the unknown number.... y. the variable is y. so now we have to think, TWICE that number, but we don’t know the number.

Now that we have the variable and we know it has to be doubled, let’s start off making the first half... we can out that into 2y. which is 2 multiplied by the unknown number.

now that we have the first half done, we have to take the 15 less. Less can mean or subtract in this kind of situation. but for this certain scenario, it will be subtraction. so the equation would be 2y - 15.
