What is the solution to this equation 6(x-4)+7=-5
sweet [91]

Answer:

X= 2

Step-by-step explanation:

6(x-4) + 7 = -5  First you distribute the 6

6x - 24 + 7 = -5 Then add like terms

6x -17 = -5 then add 17 to both sides

6x = 12 then divide 12 by 6

x = 2

Frank 20, sara20, randy15, braheem22, alice20, what is the mode for the month
Vikki [24]
If I remember correctly, more is the middle. So you first line up the numbers from least to greatest-
25,20,20,20,22
Then you count equally from each side to get to the number in the middle.
The answer would be 20
For future references, if there are two numbers in the middle, you and them together, and then divide that number by two.
Hope this helps!

Metal fatigue causes cracks to appear on the skin of older aircraft. Assume that for a certain year and model of aircraft the av
lyudmila [28]

Answer: the probability that we observe 4 cracks when inspecting a 3 m2 section is 0.034

Step-by-step explanation:

The formula for poisson distribution is expressed as

P(x = r) = (e^- µ × µ^r)/r!

Where

µ represents the mean of the theoretical distribution.

r = x represents the number of successes of the event(cracks).

From the information given,

µ = 3 cracks per 1 m² section

It means that for a 3 m² section of the aircraft, the average number of cracks would be 9

the probability that we observe 4 cracks when inspecting a 3 m2 section would be

P(x = 4) = (e^- 9 × 9^4)/4!

P(x = 4) = 0.034

Dmitry_Shevchenko [17]

Answer:

The answer to this question can be defined as follows:

In option 1, She buys 4 memory cards.

In option 2, The cost of memory is $40  

Step-by-step explanation:

Given:

Available space is = 105 GB

required space = 1000 GB

256 GB memory cost $10.

Find needed memory:

=  1000 GB - 105 GB

= 895 GB

∴ the available memory is 256 GB.

∵ 256 × 4 = 1024  GB

The total memory she have = 1024 + 105 = 1129 GB

And  she needs to buy 4 memory cards.

The cost of the four memory cards is= 4 ×10 =  $40.
