Ira Lisetskai [31]4 years ago
7 0
1.5 cups = 0.09375 gallon
per week = 7 days 
So, 0.09375(7) =0.65625 gallon /week
Or you could round it to 0.66

Two cards are dealt from a shuffled deck. What is the probability that the first card is an ace and the second card is a face ca
Zielflug [23.3K]

The probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

What is the probability of cards?

Probability is measured by counting and using basic math, such as addition and division. For example, you can multiply the number of spades in a complete deck (13) by the total number of cards in the deck (52) to get the probability of drawing a spade at random: 13 in 52, or 25%.

If you are dealt two cards successively from a standard 52-card deck, find the probability of getting an ace card on the first card and a face on the second.

you want to draw an ace. There are 4 aces out of the 52 cards in the deck so the probability of drawing an ace = 4/52.

So, the combined probability (\frac{12}{52}) . (\frac{4}{52}) = (\frac{3}{13}) . (\frac{1}{13}) = (\frac{3}{169})

= 1.78%.

The probability of a face card on the second draw = 12/52 because there are 12 face cards (J, Q, K x 4 of each) and 52 cards in the deck.

Hence, the probability that the first card is an ace and the second card is a face card is 1.78% and 12/52 respectively.

Determine if the given function can be extended to a continuous function at xequals0. If​ so, approximate the extended​ function
Akimi4 [234]

Complete Question

The  complete question is shown on the first uploaded image

Answer:

The correct option is  A

Step-by-step explanation:

Now  from the question we are given the function

        f(x) =  \frac{10^{2 x} -4}{x}

Now  as  \lim_{x \to 0} [f(x) ] =  \frac{10^{2*0} -4 }{0}

       =>    \lim_{x \to 0} [f(x) ] = - \infty

This  implies that as x\to 0 the function f(x)  \to -\infty which means that at  x = 0  the function is not continuous

If y varies directly as x, and y = 25 when x = 5, find y when x = 25.

A.125
Because to get from 5 to 25 you need to multiply by 5 so 25 times five equals 125

Is -9.2222 a irrational number? Or rational? Im so confused
finlep [7]

Answer:

  rational

Step-by-step explanation:

Any number that can be written with a finite number of digits is rational. The given number is rational. (It has 5 digits.)

__

Any repeating decimal is rational.

If this were -9.2222..., it would be -9 2/9 = -83/9, also a rational number.

_____

A number is irrational if it cannot be represented exactly as a decimal or repeating decimal. That is, its decimal fraction part continues forever without repeating.

Write the equation of the line in slope-intercept form using y=mx+b​
AnnZ [28]
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b

Then as we know it passes the y axis at (0,-3) so b= -3

So we have y=5x-3
