Express 0.003259 in standard form correct to two significant figures

explain please ​

Answers

Answer 1

Answer:

5.9 x 10^-5

Step-by-step explanation:

Move the point to the right . The power of the exponent becomes negative because we’re moving the point from left to right. The opposite is the case if we move the point to the left .

To two significant figures, move the point until you have just two figures left. So

5.9 x 10^-5 is the answer

Answer 2

Answer: 3.3×10^-3

Step-by-step explanation:

0.003259 in standard form

When you see a standard form questions like this,you have to be patient

You will have to count the zeros backward

How many zeros are in front of the 3,that's two right

That means you take the decimal to the back of 3,that means the decimal is jumping three numbers

Since you are counting backward, that will be negative

So we have,

3.259×10^-3

Now to two significant figures

You will round up the 5 behind the 2 to 1 and add to the 2

Making 3,

So we have

3.3×10^-3

What is the area of the shaded region?

Answers

Given:

Radius of in circle (r) = 2 cm

Radius of out circle (R) = 4 cm

To find:

The area of the shaded region.

Solution:

The value of π = 3.14

Area of in circle = πr²

                          = 3.14 × 2²

Area of in circle = 12.56 cm²

Area of out circle = πR²

                          = 3.14 × 4²

Area of out circle = 50.24 cm²

Area of the shaded region = Area of out circle - Area of in circle

                                            = 50.24 - 12.56

                                            = 37.68 cm²

The area of the shaded region is 37.68 cm².

What is the measure of Angle M R N? Triangle M R N. Angle N is 98 degrees. Side N M extends to form exterior angle with a measure of 109 degrees.

Answers

Answer: Angle MRN equals 11 degrees (11°)

Step-by-step explanation: Please see the picture attached for details.

The triangle MRN has been drawn such that angle N as shown equals 98 degrees. Then line NM has been extended and the exterior formed there is 109 degrees. That means angle M can be calculated as follows

Angle M = 180 - 109 {Angles on a straight line equals 180}

Angle M = 71

Now we have two angles given as angle N which is 98 degrees and angle M which is 71 degrees.

Angle MRN can now be calculated as follows;

∠ MRN = 180 - (71 + 98) {Sum of angles in a triangle equals 180}

∠ MRN = 180 - 169

∠ MRN = 11

Therefore angle MRN measures 11 degrees.

Answer:16

Step-by-step explanation:Take 98 and subtract it from 109

What is the equation of a circle with center (8,1) and radius 6?

C. (X + 8)2 + (y + 1)2 = 36
D. (X + 8)2 + (y + 1)2 = 6

Answers

Answer:

(x - 8)² + (y - 1)² = 36

None of the above

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

(x - 8)² + (y - 1)² = 6²

(x - 8)² + (y - 1)² = 36

(x - 8)2 + (x - 1)2 = 36

the function f(x)=10(2)^x models an insect population after x weeks. to the nearest whole number, what will be the population after 4 wekks

Answers

The insect population after 4 weeks will be 160 to the nearest whole number.

The student is asking about the function f(x) = 10(2)ˣ, which models an insect population after x weeks.

To find the population after 4 weeks, we need to substitute x with 4 in the function:

f(4) = 10(2)⁴

Now we calculate the value:

f(4) = 10(16) = 160

So, to the nearest whole number, the insect population after 4 weeks will be 160.

2) There are 5 roads leading from Charleston to Mattoon, 6 roads leading from Mattoon to Toledo,
and 3 roads leading from Toledo to Greenup. How many ways are there to get from Charleston to
Greenup?
A) 180
B) 14
C) 90
D) 30

Answers

Answer:

There will be 90 ways to reach Greenup from Charleston.

Step-by-step explanation:

Option C: 90 is correct.

Let's name all the ways and try to visualize the roads.

C = Charleston

M = Mattoon

T = Toledo

G = Greenup

Task = Charleston to Greenup. How many different ways to reach?

    1            1          

    2           2           1

C   3     M   3   T      2   G

     4           4           3

     5           5

                   6

So, Refer to this above diagram.

If we Start from C then go to 1 and then go to M and then go to 1 and then go to T and then go to 1 and then go G.

If you notice, in this single possibility we have 3 ways: C to 1 to M, M to 1 to T, T to 1 to G.

It means we will have: 5 x 6 x 3 = 90 number of ways to reach greenup from Charleston.

The total number of ways to get from Charleston to Greenup is option C) 90.

To determine this, multiply the number of roads for each section:

Charleston to Mattoon: 5 roadsMattoon to Toledo: 6 roadsToledo to Greenup: 3 roads

Then, multiply the numbers of roads for all the sections: [tex]5 * 6 * 3 = 90[/tex].

6. There are no x-intercepts.
O He incorrectly solved the equation x + 3 = x + 1.

Answers

Answer:

Step-by-step explanation:

He set the factored expressions equal to eachother

Mathieu made the error of setting the factored expressions equal to each other. In step 3, he incorrectly wrote x + 3 = x + 1. This is not true, and it led him to the incorrect conclusion that x = -2.

What is standard error?

It is an estimate of the standard deviation of the sampling distribution. It measures the variability of a considered sample statistic.

Suppose that we're given that:

Population standard deviation =[tex]\sigma[/tex]

Size of sample we're working on = n

Then, the standard error can be calculated as:

[tex]SE = \dfrac{\sigma}{\sqrt{n}}[/tex]

where SE denotes the standard error.

We are given that;

f(x) = x2 + 4x + 3

Now,

To find the x-intercepts of the function f(x) = x^2 + 4x + 3, you need to set the function equal to zero and solve for x:

x^2 + 4x + 3 = 0

You can factor this quadratic equation as:

(x + 3)(x + 1) = 0

Then, you can use the zero product property to find the values of x that make the equation true:

x + 3 = 0 or x + 1 = 0

Solving for x in each equation gives:

x = -3 or x = -1

Therefore, after finding the error step 3 will be f(x) = x^2 + 4x + 3 are (-3, 0) and (-1, 0).

• Tigers: P =
• Redbirds: P =
• Bulldogs: P =
•Titans: P =
a. Tigers
B. Redbirds
C. Bulldogs
D. Titans


Answers

Answer:

C. Bulldogs

Step-by-step explanation:

In this question, we want to compare several numbers with different denominators and find out which number is the least. To compare this number, we have to change the denominator into the same number by finding the least common multiple (LCM) of the 4 numbers. The factor of each number will be:

3= 3 ^1

5= 5^1

8= 2 * 2 * 2 = 2^3

2= 2^1

We can find the LCM by multiplying a higher exponent of each prime number. The LCM will be:3^1 * 5^1 * 2^3 = 120

Each number will be:

Tiger= 2/3 * 40/40= 80/120

Redbird = 4/5 * 24/24= 96/120

Bulldogs = 3/8 * 15/15 = 45/120

Titans = 1/2 * 60/60 = 60/120

As you can see, the team with the lowest chance to play is Bulldogs = 45/120

you and a friend play a game twice. what is the probability that you win both games? P(win) = 1/2

Answers

Answer:

1/4

Step-by-step explanation: 1/2*2=1/4

The probability of winning two games in a row, with each win having a 1/2 chance, is 1/4 or 25 percent, calculated by multiplying the individual probabilities for each game using the product rule.

The probability that you win a game is given as 1/2, and since the games are independent, the probability of winning both games in a row is found by multiplying the probabilities of each individual game. Using the product rule, P(win game 1 and game 2) = P(win game 1) × P(win game 2).

Since P(win) = 1/2 for each game, we simply calculate:

P(win both games) = (1/2) × (1/2) = 1/4.

Therefore, the probability of winning both games is 1/4 or 25 percent.

Which sale gives the greatest percent discount? 1) Take 25% off, 2) original price reduced by 30%, 3) on sale at 60% of the original price, 4) it depends on the original price.

Answers

Final answer:

The greatest percent discount is the option where the item is on sale at 60% of the original price. This is because you are paying the smallest percentage (60%) of the original price compared to the other options, representing the largest discount.

Explanation:

The question is pertaining to discounts and how to determine which option gives the greatest percent discount. Finding the greatest percent discount involves comparing the different percentage decreases from the original price. We can ignore any impact of sales tax for this particular comparison.

Here are the discounts rephrased in terms of how much of the original price you would pay:

25% off - You pay 75% of the original price.Original price reduced by 30% - You pay 70% of the original price.On sale at 60% of the original price - You pay 60% of the original price.

Now, comparing these percentages (75%, 70%, and 60%), the smallest percentage represents the largest discount. Therefore, option 3, where the item is on sale at 60% of the original price, represents the greatest discount as you're paying the smallest percentage of the original price. The original price does not impact which discount is greater since we are comparing percentages, not absolute values, which means the answer does not depend on the original price.

Final answer:

Comparing percent discounts shows that being on sale at 60% of the original price (Option 3) is effectively a 40% discount, which is the greatest discount among the given options.

Explanation:

The question asks about comparing different percent discounts to determine which one is the greatest. To compare the discounts, we consider a hypothetical original price and apply each discount to see which reduced price is the lowest.

Option 1: 25% off means the sale price is 75% of the original price.

Option 2: A reduction of 30% means the sale price is 70% of the original price.

Option 3: On sale at 60% of the original price means the sale price is exactly that, 60% of the original price.

Option 4: The sale that offers the greatest percent discount does not depend on the original price because percentages are relative, not absolute values.

Considering these options, Option 3, being on sale at 60% of the original price, is equivalent to a 40% discount, which offers the greatest percent discount.

Income = (4 lawns)*($27 per lawn) = $108

Expenses = ($32 for gas)+($12 for trim line) = $44

Profit = income - expenses = 108-44 = $64

----------------------------

July

Income = (12 lawns)*($20 per lawn) = $240

Expenses = ($89 for gas)+($29 for blade sharpening) = $118

Profit = income - expenses = 240 - 89 = $151

----------------------------

August

Income = (16 lawns)*($20 per lawn) = $320

Expenses = ($101 for gas)+($16 for oil) = $117

Profit = income - expenses = 320-117 = $203

----------------------------

Total profit = (june profit)+(july profit)+(august profit)

Total profit = (64) + (151) + (203)

Total profit = $418

If the final result was negative, then we would call this a loss. However, we have a positive value, so we go with a profit.

(Round to the nearest thousandth as needed.)State the appropriate conclusion. Choose the correct answer below.a. There is sufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision.b. There is insufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision. EASY POINTS!!!!! FIRST CORRECT ANSWER GETS 5 STARS PLUS A THANK YOU, AND MORE THAN 20 POINTS!!!
