How can she might choose a random sample of five students from her class of 35 students?

The graph shows the number of chairs made in a factory during one day .

GaryK [48]

Answer:

C) the factory produces 25 chairs per hour

Step-by-step explanation:

Let's find the rate of change (slope):

$let:\\(x1,y1) =(2,50)\\(x2,y2)=(4,100)\\m=\frac{100-50}{4-2} =\frac{50}{2} =25 \\$

If the reserve rate is 7% and a bank receives a deposit of $9000, how much of the $9000 is the bank free to lend?

elena55 [62]

7% Of 9000 is 630. Then subtract 630 from 9000. So your answer becomes 8370.

How to do number 6! Anyone I will cash app you

olganol [36]

Answer:

Shawna has 50, 48,46,44 or 42 yellow pencils.

Step-by-step explanation:

Here, given the total number of pencils Shawna has = 55 pencils

So, The number of YELLOW PENCIL + BLUE PENCIL = 55

or, Y + B = 55

Now let us take the given cases of blue pencils one by one:

1. If she has 5 blue pencils

Here, B = 5

So, as Y + B = 55 ⇒ Y + 5 = 55

or, Y = 5 5 - 5 = 50

Hence, Shawna has 50 yellow pencils.

2. If she has 7 blue pencils

Here, B = 7

So, as Y + B = 55 ⇒ Y + 7 = 55

or, Y = 5 5 - 7 = 48

Hence, Shawna has 48 yellow pencils.

3. If she has 9 blue pencils

Here, B = 9

So, as Y + B = 55 ⇒ Y + 9 = 55 ⇒ Y = 55- 9 = 46

Hence, Shawna has 46 yellow pencils.

4. If she has 11 blue pencils

Here, B = 11

So, as Y + B = 55 ⇒ Y + 11 = 55 ⇒ Y = 55- 11 = 44

Hence, Shawna has 44 yellow pencils.

5. If she has 13 blue pencils

Here, B = 13

So, as Y + B = 55 ⇒ Y + 13 = 55 ⇒ Y = 55- 13 = 42

Hence, Shawna has 42 yellow pencils.

If $a$, $b$, $c$, and $d$ are replaced by four distinct digits from $1$ to $9$, inclusive, then what's the largest possible valu

Anna [14]

Answer:

Correct answer is 18.3

Dollar replacement 70

Step-by-step explanation:

<u>Correct answer</u>

Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.

This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.

It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the one-digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:

9.7 + 8.6 which results to 18.3

9.6 + 8.7 yields 18.3 as well.

<u>Dollar replacement</u>

For the value of the difference to be largest, the minuend should be maximum(most possibly) and the subtrahend should be minimum

[in A-B=X, A is minuend and B is subtrahend ]

So, $a.b should be the maximum. as there is a condition that 4 digits should be distinct, the product will be maximum if we choose 2 maximum valued numbers from the given numbers. so, one of them should be 9 and the other should be 8.

Therefore, $a.b=9*8=72

As mentioned above, c.d$ should be minimum. this will be possible only when we choose 2 minimum valued numbers from the given numbers. so, one of them should be 1 and the other should be 2.

Therefore, c.d$ = 1*2 = 2

Hence, the difference = 72-2 = 70

Thus, the largest possible value of the difference $a.b - c.d$ = 70
