When 35 ÷ 7, the quotient would be 5, while 35 would be called the dividend, and 7, the divisor. I hope this helps

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a club and the seco

tia_tia [17]

Answer:

Probability to draw a club and second card is red without replacement will be $\frac{13}{102}$ or 12.75%

Step-by-step explanation:

A standard deck of cards contains number of cards = 52

And a standard deck contains number of club = 13

Now the probability of first card to be a club will be

$P_{1}=\frac{\text{Number of club in a deck}}{\text{Total number of cards}}$

= $\frac{13}{52}=\frac{1}{4}$

Now this card is separated from the deck.

Therefore, number of remaining cards = 52 - 1 = 51

Second card has been drawn from the deck without replacement.

Since number of red cards in the deck = 13 + 13 = 26

Probability of the second card drawn = $\frac{\text{Number of red cards}}{\text{Number of remaining cards}}$

$P_{2}=\frac{26}{51}$

Now probability that the first card is a club and the second card is red = $P_{1}\times P_{2}=\frac{1}{4}\times \frac{26}{51}$

= $\frac{13}{102}$

Or $\frac{13}{102}\times 100=12.75%$ %

Therefore, probability to draw a club and second card is red without replacement will be $\frac{13}{102}$ or 12.75%

The scale is evenly balanced. Explain how to find the weight (w) of one turtle.

Tomtit [17]

Answer: 8 units

Step-by-step explanation:

Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.

To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.

Really need this todayyyyyy

Bond [772]

Answer:

Q3: x1=2+i, x2=2-i Q4: x1=-3/2+i, x2=-3/2-i

Step-by-step explanation:

$x^{2} - 4x + 5 =0$

( $4$ ± $\sqrt{16 - 4*1*5}$ ) / $2$ = (

x1= 2+i

x2= 2-i

$2x^{2} +6x + 5 =0$

( $-6$ ± $\sqrt{36 - 4*2*5}$ ) / $4$ = (-6 ± $\sqrt{-4}$ )/4= (-3 ± i)/2

x1 = -3/2 +i

x2 = -3/2 -i

The regular price of a shirt is $24.50. the shirt is on sale for 10% off the regular price. what is the sale price of the shirt?

Ber [7]

Answer:

22.05

Discount = Original Price x Discount %/100

Discount = 24.5 × 10/100

Discount = 24.5 x 0.1

You save = $2.45

24.50 - 2.45

22.05!

What are the domain and range of this function y=(x+3)^2 -5

n200080 [17]

Answer: Choice A

Note: the range should be $[-5, \infty)$ . See explanation below.

===================================================

We can plug in any real number for x to get some output for y. The domain is the set of all real numbers in which we say $(-\infty, \infty)$ which is interval notation. It represents the interval from negative infinity to positive infinity.

The range is the set of possible outputs. The smallest output possible is y = -5 which occurs at the vertex (3,-5). We can get this y value or larger. So we can describe the range as the set of y values such that $y \ge -5$ and that translates to the interval notation $[-5, \infty)$ .

The square bracket says "include this endpoint" while the curved parenthesis says to exclude the endpoint. Your teacher mistakenly wrote $(-5, \infty)$ for choice A, when they should have written $[-5, \infty)$

I think either your teacher made a typo or somehow the formatting messed up. Either way, choice A is the closest to the answer.
