Any number in between -21 and -20 would suffice in this case. If there are no other conditions, let's claim that Stan's bank account balance is -20.75

Thanks for the points. We need gracious people like you.

Less than -20 but greater than -21

One possible answer is = -20.50.

= -$20.50

That's a possible balance for Stan's bank account account.

The key here is that for negative numbers, the smaller numbers are bigger than the big numbers.

E.g -2 is bigger than -3.

In a particular game, a fair die is tossed. If the number of spots showing is either four or five, you win $1. If the number of

TiliK225 [7]

Answer:

The probability that you win at least $1 both times is 0.25 = 25%.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either you win at least $1, or you do not. Games are independent. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Probability of winning at least $1 on a single game:

The die has 6 sides.

If it lands on 4, 5 or 6(either of the three sides), you win at least $1. So

$p = \frac{1}{2} = 0.5$

You are going to play the game twice.

This means that $n = 2$

The probability that you win at least $1 both times is

This is P(X = 2).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{2} = 0.25$

The probability that you win at least $1 both times is 0.25 = 25%.

Question 19 of 25

Ronch [10]

The next step in the series will be Option B

<h3>What is a Series ?</h3>

A series is the sequence of object in pattern.

From the given figure it can be seen that the red and blue colour semicircle are shifting alternately , and the number series is increasing by 1

Therefore the next step is red on the right side , blue on the left side and no. 4 written on blue

Therefore Option B is the right answer.

A line joins the point

Harrizon [31]

Intersection of the first two lines:

$\begin{cases}5x - 2y + 3 = 0\\4x - 3y + 1 = 0\end{cases}$

Multiply the first equation by 4 and the second by 5:

$\begin{cases}20x - 8y + 12 = 0\\20x - 15y + 5 = 0\end{cases}$

Subtract the two equations:

$(20x - 8y + 12)-(20x - 15y + 5)=0 \iff 7y+7=0 \iff y=-1$

Plug this value for y in one of the equation, for example the first:

$5x - 2\cdot (-1) + 3 = 0\iff 5x+5=0 \iff x=-1$

So, the first point of intersection is $(-1,-1)$

We can find the intersection of the other two lines in the same way: we start with

$\begin{cases}x=y\\x=3y+4\end{cases}$

Use the fact that x and y are the same to rewrite the second equation as

$x=3x+4 \iff 2x=-4 \iff x=-2$

And since x and y are the same, the second point is $(-2, -2)$

So, we're looking for a line passing through $(-1,-1)$ and $(-2, -2)$ . We may use the formula to find the equation of a line knowing two of its points, but in this case it is very clear that both points have the same coordinates, so the line must be $y=x$

In the attached figure, line $5x - 2y + 3 = 0$ is light green, line $4x - 3y + 1 = 0$ is dark green, and their intersection is point A.

Simiarly, line $x=y$ is red, line $x = 3y + 4$ is orange, and their intersection is B.

As you can see, the line connecting A and B is the red line itself.

Answer:

Cross-sectional study.

Step-by-step explanation:

- In a cross-sectional study, data are observed, measured, and collected at one point in time.

- In a prospective (or longitudinal) study, data are collected in the future from

groups sharing common factors.

- In a retrospective (or case-control) study, data are collected from the past by going

back in tirme (through exanmination of records, interviews, arıd so on).

the u.s department of agriculture reported that 57 out of every 100 milk drinkers drink skim milk. if a storeowner orders 24 gal

S_A_V [24]

STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.

57/100= 0.57 (= 57%)

STEP 2:
Multiply percentage by the total gallons ordered (24).

=24 gallons * 0.57
=13.68 gallons

ALTERNATIVE METHOD (use which works best for you)

Set up a proportion. 57 to 100 is x out of 24 gallons.

x= number skim gallons to order

57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x

ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons

Hope this helps! :)
