Answer: The solved value of x = \dfrac{-q}{s}

Step-by-step explanation:

The given equation : a-q=a+sx

As per the given equation , we apply sum properties of equality.

To solve for x , first we subtract s from both sides , we get

a-q-a=a+sx-a  (By Subtraction property of equality)

-q=sx

Now , we divide both sides by s , we get

\dfrac{-q}{s}=x (By Division property of equality)

Therefore , the solved value of x = \dfrac{-q}{s}

Jean's bedroom is 11 feet by 14 feet. She has chosen a carpet which costs $33.30 per square yard. This includes installation.
Allisa [31]

Answer:

The room will cost $569.80 to carpet.

Step-by-step explanation:

Recall that 1 square yard = 9 square feet.

The area of the bedroom, in square feet, is (11 ft)(14 ft) = 154 ft^2.

Converting this to square yards:

154 ft^2      1 yd^2

------------ * ------------ = 17.1 yd^2

       1          9 ft^2

17.1 yd^2     $33.30

------------- * ------------- = $569.80

       1            1 yd^2

The room will cost $569.80 to carpet.

Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t
KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability  of getting spade=p=\frac{13}{52}=\frac{1}{4}

Probability,P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Probability  of getting no spade=q=1-p=1-\frac{1}{4}=\frac{3}{4}

By binomial theorem of probability

P(X=x)=\binom{n}r}p^rq^{n-r}

P(x\geq 7)=1-P(x\leq 6)

The probability of drawing at least 7 spades=1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r

The probability of drawing at least 7 spades=0.139

The lunch bill for marty and breanna at a diner totaled $18.37. Tax on the meal was 6%, and they wanted to leave a 15% tip. How
elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

The lunch bill for marty and breanna at a dinner totaled $18.37. Tax on the meal was 6%. The amount of tax on the meal would be

6/100 × 18.37 = 0.06 × 18.37 = $1.1022

Cost of the meal including the tax would be

18.37 + 1.1022 = $19.4722

They wanted to leave a 15% tip. The amount of the tip would be

15/100 × 18.37 = 0.15 × 18.37 = $2.7555

Therefore, the total cost of the meal, including tax and tip would be

19.4722 + 2.7555 = $22.23

lucas and erick are factoring the polynomial 12x3 – 6x2 8x – 4. lucas groups the polynomial (12x3 8x) (–6x2 – 4) to factor. eric
Maurinko [17]

Answer:

Both the students were correct.

Step-by-step explanation:

Given : The polynomial is - 12 x^3 - 6 x^2 + 8 x - 4

To find : Who correctly grouped the terms to factor.

Lucas group the polynomial - ( 12 x^3 + 8 x ) + ( - 6 x^2 - 4 )

Now, we solve the Lucas polynomial

(12x^3+8x) + (-6x^2-4)= 4x(3x^2+2 )-2(3x^2+2)

(12x^3+8x) + (-6x^2-4)= (3x^2+2 )(4x-2)

(12x^3+8x) + (-6x^2-4)= 2(3x^2+2)(2x-1)

Erick group the polynomial - (12x^3-6x^2) + (8x- 4)

Now, we solve the Erick polynomial

(12x^3-6x^2) + (8x- 4)=6x^2(2x-1)+4(2x-1)

(12x^3-6x^2) + (8x- 4)=(6x^2+4)(2x-1)

(12x^3-6x^2) + (8x- 4)=2(3x^2+2)(2x-1)

The factors of Lucas and Erick are same.

Each grouping leads to the same result. 

Therefore, Both students are correct.
