is how many times as great as 4 x 10*-6?

2 x10*3

2 x 10 *9

2 x 10 *-9

2 x 10-*_•-3

**Answer:**

[tex]\huge\boxed{2\times10^3}[/tex]

**Step-by-step explanation:**

[tex](8\times10^{-3})\div(4\times10^{-6})=\dfrac{8\times10^{-3}}{4\times10^{-6}}=\dfrac{8}{4}\times10^{-3-(-6)}=2\times10^{-3+6}=2\times10^3[/tex]

Used:

[tex]\dfrac{a^n}{a^m}=a^{n-m}\ \text{for}\ a\neq0[/tex]

Multiply the two fractions. Simplify your answer. 1/2 x 4/7

**Answer:**

2/7

**Step-by-step explanation:**

The **solution **of **fractions **after multiplying the two fractions would be [tex]\dfrac{2}{7}[/tex].

Given that,

**Multiply **the two fractions,

[tex]\dfrac{1}{2} \times \dfrac{4}{7}[/tex]

Used the concept of **multiplication **which states that,

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, simplify the **fractions **by multiplying,

[tex]\dfrac{1}{2} \times \dfrac{4}{7}[/tex]

[tex]\dfrac{4}{14}[/tex]

Simplify for the simplest form,

A study of more than 3,000 toco toucans found that their weights were approximately Normally distributed, with a mean

of 20 ounces and a standard deviation of 2.3 ounces. Let Y be the weight of a randomly chosen toco toucan. Which of

the following correctly interprets the value of P(Y < 16)?

Find the Z-table here.

O P(Y< 16) = 0.50. About 50% of all toco toucans weigh less than 16 ounces.

OP(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces.

O P(Y < 16) = 0.959. About 95.9% of all toco toucans weigh less than 16 ounces.

P(Y < 16) = 0.041. About 4.1% of the toco toucans from this group weigh less than 16 ounces.

O P(Y< 16) = 0.959. About 95.9% of the toco toucans from this group weigh less than 16 ounces.

Using the **normal distribution**, it is found that the **correct option** is:

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

ItIn this problem:

**P(Y < 16)** is the p-value of Z when X = 16, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{16 - 20}{2.3}[/tex]

[tex]Z = -1.74[/tex]

[tex]Z = -1.74[/tex] has a p-value of 0.041.

This is valid for the **entire population**, hence, the **correct interpretation** is:

Examine the system of equations.

y = –3x – 2,

y = 7

The value of x is ______.

The solution to this system of equations is _______.

**Answer:**

[tex]\boxed{\boxed{\sf x=-3}}[/tex]

**Step-by-step explanation:**

[tex]\sf y = -3x - 2[/tex]

[tex]\sf y=7[/tex]

**We'll substitute y into the equation:**

[tex]\sf 7 = -3x - 2[/tex]

**Switch sides:**

[tex]\sf -3x-2=7[/tex]

**Add 2 to both sides **

[tex]\sf -3x-2+2=7+2[/tex]

[tex]\sf -3x=9[/tex]

**Divide both sides by -3:**

[tex]\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}[/tex]

A bag of 8 apples costs $1.50 at Sam’s Orchard. a. At this same rate, how much would 18 apples cost? b. How many apples could you buy for $5.00

**Answer:**

cost for 18 apples: $3.38

$5 will buy 26 apples

**Step-by-step explanation:**

let 'a' = apples

1.50/8 = cost per apple

$0.1875 for one apple

cost for 18 apples: 0.1875 x 18 = $3.38

5.00 / 0.1875 = number of apples for $5 → 26

3 3/4 divided by 1 1/3 in fraction answer

**Answer: 4/3**

**Step-by-step explanation:**

Find three consecutive even integers such that the

sum of the smallest and the largest is 36.

n= smallest integer

n+2= middle integer

n+4= largest integer

n + n + 4 = 36

2n+ 4 = 36

2n=32

n= 16 which means that the smallest integer is 16

then you substitute it into the equation for the largest integer

n+4=20

16, 18, 20 is the answer
