Answer:

The possibel values of x is 5, 6, 7, 8.

Step-by-step explanation:

Integer is a positive or negative whole number.

In this case, x must be positive and it have to be greater than 4 but smaller than 9 so the possible values will be 5, 6, 7 and 8.

It says [tex]x[/tex] is greater than [tex]4[/tex] and it is less than [tex]9[/tex]

The first value which is greater than [tex]4[/tex] is [tex]5[/tex] and the value which is less than [tex]9[/tex] is [tex]8[/tex]. So the answer would be all integers from [tex]5[/tex] to [tex]8[/tex] (inclusive)

[tex]5, 6, 7, 8[/tex] would be the answer! :D

x ≤ -4 will result in an imaginary number. (From the graph it's actually 3.5, so if you want to view in REAL number then it's x ≤ -3.5 which will result in imaginary numbers.)

But if you want an integer then It's x ≤ -4

Real Number as it's x ≤ -3.5

Answer:

This is the concept of scale factors; The length of the larger figure will be calculated as follows;

linear scale factor=[length of larger figure]/[length of smaller figure]

plugging the values in the above formula we get:

let the length of the larger figure be x;

thus;

x/12=4/3

multiplying both sides by 12 to solve for x we get:

12*x/12=4/3x12

x=16

thus the length of the larger figure is x=16

Answer:16

Step-by-step explanation:

12 times 4/3 is 4^2 or 16

Answer:

7r-8

Step-by-step explanation:

yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14

Firstly we will solve -1r +8r

+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r

Now we move on to +6-14

this is just simple addition and subtraction

what is 14-6 it is -8

-14 overpower 6 so we use its sign

Lastly we put it all together and get

7r - 6

Answer:

no asnwer

Step-by-step explanation:

first step:

-5x+y+5z=27

which is

6y+z=15

add -6y-z=-16

which will be 0=-1

this means that there is no answer and that the statement is false.

Step-by-step explanation:

This question is incomplete, the complete question is;

X and Y are independent Gaussian (Normal) random Variables. X has mean 13.9 and variance 5.2; Y has mean 6.9 and variance 3.8. . (a) Calculate P( W> 10)

Answer:

P( W> 10) is 0.1587

Step-by-step explanation:

Given that;

X ⇒ N( 13.9, 5.2 )

Y ⇒ N( 6.9, 3.8 )

W = X - Y

Therefore

E(W) = E(X) - E(Y)

= 13.9 - 6.9 = 7

Var(W) = Var(X) + Var(Y) -2COV(X.Y)

[ COV(X,Y) = 0 because they are independent]

Var(W) = 5.2 + 3.8 + 0

= 9

Therefore

W ⇒ N( 7, 9 )

so

P( W > 10 )

= 1 - P( W ≤ 10 )

= 1 - P( W-7 /3   ≤   10-7 /3 )

= 1 - P( Z ≤ 1 )           [ Z = W-7 / 3 ⇒ N(0, 1)  ]

from Standard normal distribution table, P( Z ≤ 1 )  = 0.8413

so

1 - P( Z ≤ 1 )  = 1 - 0.8413 = 0.1587

Therefore P( W> 10) is 0.1587

If the given 5 units and 10 units are both legs of the right triangle, then the answer should be 11.18 units.

Answer:

7474/6=1245 2/3

hi!

so the original equation is (x^2 -121) / x+ 11.

Those two equations look similar...

well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).

So if we factor that out, we get:

( (x + 11) * (x-11) )/ (x + 11)

we can cancel the x+11 on the top and the x+11 on the bottom out.

that leaves us with x-11.

Answer:

The number of ways to form different groups of four subjects is 4845.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]

In this case, 4 subjects are randomly selected from a group of 20 subjects.

Compute the number of ways to form different groups of four subjects as follows:

[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]

[tex]{20\choose 4}=\frac{20!}{4!\times (20-4)!}[/tex]

      [tex]=\frac{20\times 19\times 18\times 17\times 16!}{4!\times 16!}\\\\=\frac{20\times 19\times 18\times 17}{4\times3\times 2\times 1}\\\\=4845[/tex]

Thus, the number of ways to form different groups of four subjects is 4845.

Answer:

The answer may be 68?

Step-by-step explanation:

Answer:

44°

Step-by-step explanation:

First, m ∠ D=112° and  ∠ABC are congruent in a parallelogram and congruent angles have same measure so m ∠ ABC=112° as well

Second, ∠ABC and ∠CBE are supplementary angels so they add up to 180° because adjacent angles that form a line are suplementary, therefore, ∠CBE=180-112=68°

Third, ∠CBE≅∠BCE because the ΔCEB is isosceles since is given CE≅BE and base angles of isosceles triangles are congruent.

Congruent ∠s have same measure so m∠BCE =68° as well

Last sum of angles in a Δ is 180° so from  ΔCEB we have

m ∠E = 180-68-68=44°

Answer:

Two weighing

Step-by-step explanation:

In the context, it is given that one of the three coins is fake and the other two are real. It is also mentioned that the fake coin is either heavier or lighter than the other two real coins.

Now to find the fake coin, we take a balance scale and lace one coin on one pan of the balance and place the second coin on the other pan of the same balance. We keep the third coin aside.

Now we check the balance scale. If the scale is balance, then we can conclude that the coin that we kept aside is the fake coin as both the real coins have same weight.

Now we replace the one of the coin on the pan with the coin that is kept aside and check the balance. Remember now on the pan, there is one real coin and one fake coin. The balance scale will be dis-balance as the fake coin is either heavy or light than the real coin. Thus we can identify the fake coin.
