Answer:

62 is 90.5% of what number?  68.51 (I think)

Answer:

n = 28

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc, then

35 + m = 0.5 × 98 = 49 ( subtract 35 from both sides )

m = 14

∠ n is at the centre subtended on the same arc as ∠ m , thus

n = 2m = 2 × 14 = 28

Answer:

30, 60, 90

Step-by-step explanation:

since there are 6 x's in total, and there are a total of 180 degrees in any triangle, we do 180/6= 30

so now we know x=30, 2x=60, and 3x=90

Answer:

sample proportion of defective items

Step-by-step explanation:

The p-chart is a type of chart in which the sample is taken periodically from the production process, so as to determine if the population proportion of defective items in the sample falls within the control limits on the chart.

For a P-chart, as the sample size gets larger it turns more into a normal distribution making it possible to approximate the distribution of the proportion defective.

Answer:

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.

Step-by-step explanation:

Let us recall some transformation knowledge.

We know that

if y = f(x), then y = f(x) + b simply means a transformation of (0, b).

In other words, if we add some constant let say 'b' in the output or y-value, the graph simply shifts upward by b units.

Given that

f(x) = x

so

f(x+1) = x+1 means the parent function f(x) = x has been shifted 1 unit upward.

Please check the attached diagram.

Thus, we conclude that:

In the diagram,

The blue line indicates that the parent function has been shifted 1 unit upward.

Answer:

Tank B

Step-by-step explanation:

A pet store has three fish tanks, each holding a different volume of water and a different number of fish.

a) Tank A has 5 fishes with a volume of 40 liters.

Volume per fish = 40 liters/5 fishes

= 8 liters/fish

b) Tank B has 12 fishes with a volume of 100 liters.

Volume per fish = 100 liters/12 fishes

= 8.33 liters/ fish

c) Tank C has 23 fishes with a volume of 180,000 milliliters.

Convert 180,000 milliliters to liters

1 milliliter = 0.001 liter

180,000 milliliters = x

x = 180,000ml × 0.001 l

x = 180 liters

Volume per fish = 180 liters/23 fishes

= 7.8260869565 volume per fish

Approximately = 7.83 liters/fish

Which tank has the greatest volume per fish?

The tank that had the greatest volume per fish is Tank B at 8.33 liters/ fish

Answer:

x-intercept is ([tex]- \frac{1}{2}, 0[/tex]) and y-intercept is ([tex]0, 2[/tex])

Step-by-step explanation:

We solve the equation when x=0. Let's try that with [tex]y+2=4(x+1)[/tex]

First, let's simplify it so that it resembles [tex]y=mx+b[/tex] more noticeably

[tex]y = 4x + 4 - 2 \\y = 4x + 2[/tex]

Now let's plug in 0 for x to find the y-intercept:

[tex]y = 4\cdot 0 + 2\\y = 2[/tex]

We solve the equation when y=0. Let's try this from the simplified equation we got ([tex]y = 4x + 2[/tex])

[tex]0 = 4x + 2\\-2 = 4x\\\frac{-2}{4} = x\\x = - \frac{1}{2}[/tex]

We must remind ourselves that all y-intercepts have an x that is equal to 0 and that all x-intercepts have a y equal to 0.

That means that our x-intercept will be ([tex]- \frac{1}{2}, 0[/tex]) and our y-intercept will be ([tex]0, 2[/tex])

This corresponds to the 3rd option counting from the left.

Good luck!

Answer:

question 4. The right answers are 1,3 and 4

Question 5. No they are not balanced.

Step-by-step explanation:

1.

7/9 * 8 = 6  2/9

56/9 = 6 2/9

2.

8 + 11.5 = 20.5

19.5 ≠ 20.5

3.

23.42 - 8 = 15.42

15.42 = 15.42

4.

11 * 8 = 88

88 = 88

5.

40/8 = 6

40/8 ≠ 6

Answer:

wouldnt opposite of 4 just be -4

and wouldnt -2 just be at -2?

Step-by-step explanation:

hope this helps <3

Answer:

1. Negative 4

2. Negative 2

Step-by-step explanation:

1. Opposite of positive 4 is negative 4.

Negative 4 will be below sea level, so on the number line it will be below the zero, on -4.

2. Negative 2

Negative 2 will be below sea level, so on the number line it will be below the zero, on -2.

I hope it makes sense.

Follows are the solution to this question:

Step-by-step explanation:

[tex]95 \% \[/tex] the confidence level for z:

[tex]\alpha = 1 - 95 \% \\\\[/tex]

   [tex]= 1 - 0.95 \\\\ = 0.05[/tex]

[tex]\to \frac{\alpha}{2} = \frac{0.05}{2} = 0.025\\\\\\to Z \ \frac{\alpha}{2} = Z_{0.025} = 1.96[/tex]

Calculating the Margin of error:

[tex]E = Z\ \frac{\alpha}{2} \times ( \frac{\sigma}{\sqrt{n}})[/tex]

   [tex]= 1.96 \times ( \frac{5000}{\sqrt{\sqrt{100}}})\\\\= 980[/tex]

Answer:

17

Step-by-step explanation:

To find how many notes of Rs. 500 he has, we need to find out the total value of all the Rs. 500 notes.

Total value of Rs. 20 notes = 20 × 40

                                             = 800

Total value of Rs. 1000 notes = 1000 × 20

                                                 = 20 000

Total value of Rs. 500 notes = 29 300 - 800 - 20 000

                                                = 8500

No. of Rs. 500 notes = 8500 ÷ 500

                                   = 17

Rohit has total 17 notes of Rs.500

" Unitary method is the process of finding value of one unit using which we can find the value of other units."

According to the question,

Number of Rs.20 notes = 40

Total amount of Rs.20 = 20 × 40

                                     = Rs.800

Number of Rs.1000 notes = 20

Total amount of Rs.1000 = 20 × 1000

                                         = Rs.20,000

Total amount of Rs.20 and Rs.1000 notes = 20,000 +800

                                                                      = Rs.20,800

Made a payment of Rs.29,300

Left amount of Rs.500 notes = 29,300 -20,800

                                                = Rs.8500

Number of Rs.500 notes = 8500 ÷ 500

                                          = 17 notes of Rs.500

Hence, Rohit has total 17 notes of Rs.500.

Step-by-step explanation:

81/9 is 9

9 times 4 is 36

Answer:

Hi there the answer is 81/36. Hope this helps! c:

Step-by-step explanation:

First, figure out what ratio was used to make 9, 81.

You can recall that 9 x 9 = 81.

Therefore you must multiply the bottom of the fraction by 9 as well in order to create the correct ratio.

Thus, 4 x 9 = 36.
