The equation has no solutions because when you subtract 3x from both sides, you are simply left with 8 = -5, which isn't true. In essence, there are no values of x for which the equation is true. Thus, the equation has no solutions.

Kitty [74]

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

Given f(x)=-3x+3solve for x when f(x)=6​
natali 33 [55]

Answer:

x = -1

Step-by-step explanation:

Given: f(x) =  - 3x  + 3

Solve for x, When: f(x) = 6

Step by step:

- 3x + 3 = 6

- 3x = 6 - 3

- 3x = 3

x = 3 \div  - 3

\boxed{\green{x =  - 1}}

How to use the break apart strategy to find 247+ 358 in words
r-ruslan [8.4K]
247 is equal to 200+40+7.

358 is equal to 300+50+8.

To find the answer, add 200+300=500.
40+50=90
7+8=15

500+90+15=605
