0.975 is P(x ≥242) with a mean of 266 and standard deviation of 12

The required value of P(x> 242) = is 0.975 for normal distribution. Option D is correct.

The normal distribution has a mean of 266 and a standard deviation of

12. What is P(x> 242) is to determine.

Normal distributions can be altered to standard normal distributions by the formula:

Z = (X - μ)/σ

Where x is a value from the initial normal distribution, μ is the mean of the initial normal distribution, and σ is the standard deviation of the initial normal distribution. The standard normal distribution is periodically called the z distribution.

Now,
z = X - 266 /12
p(x > 242) = P [(X - 266)/12 ≥ (242 - 266)/12]
p(x > 242) = P [z ≥ -24/12]
p(x > 242) = P [z ≥ -2]
p(x > 242) = P [z ≤ 2]
p(x > 242) = 0.975  (from Z table).

Thus, the required value of P(x> 242) = is 0.975. Option D is correct.

Step-by-step explanation:

Since y= -7x you will want to substitute the y in the other equation.

2x -(-7x) = -9

2x + 7x = -9

9x = -9

so x will be -1

y= -7(-1)

x= -1

y= 7

Answer:

x = -1 , y =7      (-1,7)

Step-by-step explanation:

[tex]y=-7x\\2x-y = -9\\[/tex]

[tex]2x+7x = -9[/tex]

[tex]2x+7x = 9x\\[/tex]

[tex]9x = -9\\[/tex]

[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]

[tex]x = -1\\[/tex]

Answer:

As given,

Per hour cost of Jack's plumbing = $100

Also,

Al's plumbing charges = 75x + 50 where x = time in hours .

Now,

Al's plumbing cost for 4 hours:

Here , x = 4

⇒75x + 5 = 75(4) + 50 = 300 + 50 = 350

∴ we get

Al's plumbing cost for 4 hours = $350

Now,

As Jack cost for 1 hour = $ 100

⇒ For 4 hour = 4×$100 = $400

∴ we get

Jack's plumbing cost for 4 hours = $400

As we can see that

$ 400 > $350

⇒Jack's plumbing cost for 4 hours  >  Al's plumbing cost for 4 hours

Now,

Al's plumbing charges = 75x + 50 where x = time in hours .

For 1 hour

75x + 50 = 75(1) + 50 = 125

Al's 1 hour cost = $125

whereas Jack Plumbing cost for 1 hour  = $100

∴ we get

$125 > $100

⇒Al's 1 hour cost > Jack's 1 hour cost

Now,

Al's 2 hour cost

75x + 50 = 75(2) + 50 = 150 + 50 = 200

Al's 1 hour cost = $200

whereas Jack Plumbing cost for 2 hour  = $200

∴ we get

$200 =  $100

⇒Al's 2 hour cost = Jack's 2 hour cost

Now,

Al's 3 hour cost

75x + 50 = 75(3) + 50 = 225 + 50 = 275

Al's 1 hour cost = $275

whereas Jack Plumbing cost for 3 hour  = $300

∴ we get

$275 <   $300

⇒Al's 3 hour cost < Jack's 3 hour cost

Als0,

Jack's plumbing cost for 4 hours  >  Al's plumbing cost for 4 hours

∴ we get

We can not say that Als Plumbing charge less than Jacks Plumbing for all repair jobs.

Because the charge is fluctuating ,

For 1 hour , Aly' charge is grater whereas The 2 hour cost of Jack's is higher.

So, the Correct answer is - No, Al's Plumbing charge is not always less than Jacks Plumbing for all repair jobs.

Answer:

True: The smaller angle is 36°; The larger angle is 54°

False: The smaller angle is 18°. The larger angle is 72°

If you create an equation using this scenario, it would be (18+x)+x=90, because complementary angles sum up to 90°. Add the like terms to get 18+2x=90. Subtract 18 on both sides to get 72. Divide 2 on both sides to result with x=36. Subtract 90 with 36 to get 54. The smaller angle is 36° and the larger angle is 54°.

Answer:

The 14 should be 14-x.

x=6

Step-by-step explanation:

The 14 should be 14-x

24/(14-x)=18/x

24x=18(14-x)

24x=252-18x

24x+18x=252

42x=252

x=252÷42=6

$344.79

Step-by-step explanation:

379.99 decrease 15% =

379.99 × (1 - 15%) = 379.99 × (1 - 0.15) = 322.9915

322.9915 increase 6.75% =

322.9915 × (1 + 6.75%) = 322.9915 × (1 + 0.0675) = 344.79342625

The probability of getting someone in the 18-21 age bracket or someone who agreed to respond [tex]= 0.365[/tex]

Step-by-step explanation:

The counts are as follows  

Age Group  No of people contacted No of refusals      Total  

18-21               88                                  8                       96

22-29              240                                  42                       282

Total              328                                  50                       378

The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is

[tex]= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365[/tex]

Answer:

50 degrees

Step-by-step explanation:

You can see that angle ADC is composed of angle ADB and angle BDC

Angle ADB is 38 degrees and angle BDC is 12 degrees

Therefore angle ADC is 50 degrees

Angle ADC is opposite from angle ABC so they are congruent.

So angle ABC is 50 degrees

Step-by-step explanation:

-5x + 3y, you can’t add those together since they aren’t like numbers

3x - 7y, can’t be done either since again, they aren’t like numbers.

like numbers include the same variable or no variable, which means you cant do -5x + 3y but you can to -5x + 3x. you can add those together since both of the numbers have the variable “x” while 3y and 7y have the same variable “y” therefore those can be added together.

since there isn’t a way to add those, both of those answers are not only wrong, but they’re also in simplest form.
