Step-by-step explanation:

Q=0

Answer:

Y=-5

X=6

Step-by-step explanation:

set x =0 then solve then set y=o and solve

Answer:

5x - 6y = 30

6y = 5x - 30

Y = 5/6x - 5

y intercept = -5

Therefore (0, -5)

0 = 5/6x - 5

5/6x = 5

x = 6

x intercept = 6

therefore (6,0)

answer : The x-intercept is (6, 0), the y-intercept is (0, –5).

x intercept =

Answer:

[tex]x=5,y=4[/tex]

Step-by-step explanation:

[tex]2x-3y=-2[/tex]

Add 3y to both sides:

[tex]2x-3y+3y=-2+3y[/tex]

[tex]2x=-2+3y[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2}=-\frac{2+3y}{2}[/tex]

[tex]x=\frac{-2+3y}{2}[/tex]

Substitute this into the second equation:

[tex]4* \frac{-2+3y}{2}+y=24[/tex]

[tex]2\left(3y-2\right)+y=24[/tex]

[tex]7y-4=24[/tex]

Add 4 to both sides:

[tex]7y-4+4=24+4[/tex]

[tex]7y=28[/tex]

Divide both sides by 7:

[tex]\frac{7y}{7}=\frac{28}{7}[/tex]

[tex]y=4[/tex]

We know that [tex]x=\frac{-2+3y}{2}[/tex]

Thus, [tex]x=\frac{-2+3* \:4}{2}[/tex]

[tex]x=\frac{10}{2}[/tex]

[tex]x=5[/tex]

Answer:

using elimination rule

multiply equation 2 by 3

we get, 12x+3y=72

now solve both equation

2x-3y= -2

(+)12x+3y=72

14x=70

x=70/14=5

put value of x in any of the equation y=4

Step-by-step explanation:

Hope this helps!!!

x = a number

7 + 2x = 21

Subtract 7 from both sides

2x = 14

Divide both sides by 2

x = 7

7 is the only number that makes this sentence true.

Answer:

The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].

Step-by-step explanation:

The marginal cost function ([tex]C(x)[/tex]) is the derivative of the cost function ([tex]c(x)[/tex]), then, we should integrate the marginal cost function to find the resulting expression. That is:

[tex]c(x) = \int {C(x)} \, dx + C_{f}[/tex]

Where:

[tex]C_{f}[/tex] - Fixed costs, measured in US dollars.

If we know that [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] and [tex]C_{f} = \$\,10[/tex], then:

[tex]c(x) = 0.06\int {e^{0.08\cdot x}} \, dx + 10[/tex]

[tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex]

The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].

Answer:

Mean = 11.3 grams

Standard Deviation = 3.5 grams

Step-by-step explanation:

Mean is affected by change of origin but standard deviation is not affected. Hence the scale weighed items 1.5 grams affect only the mean not standard deviation. Hence, the mean for new food item is 12.8 - 1.5 = 11.3 grams as weight gain by 1.5 gram due to wrong calibration and the standard deviation remains the same as 3.5 grams.

Answer:

[tex]P(X_s^c|X_F) =0.2[/tex]

[tex]P(X_s^c|X_F) =0.31[/tex]

[tex]P(X_s^c|X_F) =0.331[/tex]

Step-by-step explanation:

From the given information:

Let represent [tex]X_F[/tex] as the first player getting an ace

Let [tex]X_S[/tex] to be the second player getting an ace and

[tex]\sim X_S[/tex] as the second player not getting an ace.

So;

The probabiility of the second player not getting an ace  and the first player getting an ace can be computed as;

[tex]P(\sim X_S| X_F) = 1 - P(X_S|X_F)[/tex]

[tex]P(X_S|X_F) = \dfrac{P(X_SX_F)}{P(X_F)}[/tex]

Let's determine the probability of getting an ace in the first player

i.e

[tex]P(X_F) = 1 - P(X_F^c)[/tex]

[tex]= 1 -\dfrac{(^{2n-2}_n)}{(^{2n}_n)}}[/tex]

[tex]= 1 - \dfrac{n-1}{2(2n-1)}[/tex]

[tex]= \dfrac{3n-1}{4n-2} --- (1)[/tex]

To determine the probability of the second player getting an ace and the first player getting an ace.

[tex]P(X_sX_F) = \text{ (distribute aces to both ) and (select the left over n-1 cards from 2n-2 cards}[/tex][tex]P(X_sX_F) = \dfrac{2(^{2n-2}C_{n-1})}{^{2n}C_n}[/tex]

[tex]P(X_sX_F) = \dfrac{n}{2n -1}---(2)[/tex]

[tex]P(X_s|X_F) = \dfrac{2}{1}[/tex]

[tex]P(X_s|X_F) = \dfrac{2n}{3n -1}[/tex]

Thus, the conditional probability that the second player has no aces, provided that the first player declares affirmative is:

[tex]P(X_s^c|X_F) = 1- \dfrac{2n}{3n -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{n-1}{3n -1}[/tex]

Therefore;

for n= 2

[tex]P(X_s^c|X_F) = \dfrac{2-1}{3(2) -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{1}{6 -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{1}{5}[/tex]

[tex]P(X_s^c|X_F) =0.2[/tex]

for n= 10

[tex]P(X_s^c|X_F) = \dfrac{10-1}{3(10) -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{9}{30 -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{9}{29}[/tex]

[tex]P(X_s^c|X_F) =0.31[/tex]

for n = 100

[tex]P(X_s^c|X_F) = \dfrac{100-1}{3(100) -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{99}{300 -1}[/tex]

[tex]P(X_s^c|X_F) = \dfrac{99}{299}[/tex]

[tex]P(X_s^c|X_F) =0.331[/tex]

Answer:

Did you ever get the answer

Step-by-step explanation:

Answer:

45

Step-by-step explanation:

Answer:

45 square units

Step-by-step explanation:

The variable is the letter like x or y. The coefficient is the number next to the variable like the 2 in 2x or if its just x it would be 1. The constant is the number by itself usually at the end.

Example 2x+5

Variable is x constant is 5 and coefficient is 2. Sorry i didn't answer the actual question and just told you how to find it but those expressions don't have any of these things.

Answer:

-1 and 1/3

Step-by-step explanation:

I replaced each variable with 1. Other than that I just guessed and got it right lol

Answer:

b + 5

Step-by-step explanation:

If there are 5 more girls and b represents boys, then adding 5 to b (boys) gives you the number of girls. Hope this helps!

Answer:

The second one

Step-by-step explanation: 27-5=22 then u divide 22 divided by 2 and you get 11 then you add five girls to the 11 and you get 16 so there's 11 boys and 16 girls at the party which makes the equation 11+5=16 so the answer is number b (the second one).

Answer:

Midpoint = (1,3)

Distance = 10√2

Step-by-step explanation:

Midpoint

[tex]Midpoint = \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-4,\:8\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)\\\\=\left(\frac{6-4}{2},\:\frac{-2+8}{2}\right)\\\\=(\frac{2}{2} , \frac{6}{2} )\\\\Simplify\\=\left(1,\:3\right)[/tex]

Distance

[tex]Distance = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\(-4,8)=(x_1,y_1)\\(6,-2)=(x_2,y_2)\\\\d=\sqrt{\left(6-\left(-4\right)\right)^2+\left(-2-8\right)^2}\\\\d = \sqrt{(6+4)^2+(-2-8)^2}\\ \\d = \sqrt{(10)^2 +(-10)^2}\\ \\d = \sqrt{100+100} \\\\d = \sqrt{200}\\ \\d = 10\sqrt{2}[/tex]
