What is the median of the data set: {24, 31, 12, 38, 12, 15}A)12B)19.5C)24D)23.5

Answer:

First, let's just pick an arbitrary number as an example 7.031.

the 1 is in the thousandth place, so we can represent this as [tex]7\frac{31}{1000}[/tex].

This is so because determining what denominator of a decimal number is can be known through what non-zero digits is on the right-most side of the number.

Step-by-step explanation:

Answer:

The third digit after a decimal point is in the "thousandth" place.

Therefore, to convert a decimal that terminates after three decimal places to a fraction, simply write the digits (without leading zeros) as the numerator and 1000 as the denominator.

For example:

[tex]12.345=\dfrac{12345}{1000}[/tex]

[tex]0.932=\dfrac{932}{1000}[/tex]

Answer:

Step-by-step explanation:

21(5m - 3) = 63*9

105m - 63 = 567

105m = 630

m = 6

Answer:

2/21

Step-by-step explanation:

5m=9/21+3/63

5m=27/63+3/63

5m=30/63

5m=10/21

m=10/21/5

m=10/21 x 1/5

m=2/21

Answer:

The confidence level is the percentage of times you expect to get close to the same estimate if you run your experiment again or resample the population in the same way. The confidence interval consists of the upper and lower bounds of the estimate you expect to find at a given level of confidence.

Answer:

(8, 63)

Step-by-step explanation:

Substitute 63 for y and solve for x. x =8.

Answer:

Step-by-step explanation:

In the given arithmetic series,

To find the sum of the series, we need to find the number of terms (n) at first. So,

[tex]a_{n} = a + (n - 1)d\\38 = 6 + (n - 1) 4\\38 - 6 = 4n - 4\\32 = 4n - 4\\32 + 4 = 4n\\36 = 4n\\36 \div 4 = n\\\boxed{9 = n}[/tex]

Now, let's find the sum of the arithmetic series (Sₙ).

[tex]S_{n} = \frac{n}{2} [2a + (n - 1)d]\\S_{n} = \frac{9}{2} [2*6 + (9 -1)4]\\S_{n} = \frac{9}{2} [12+ (8*4)]\\S_{n} = \frac{9}{2} [12+ 32]\\S_{n} = \frac{9}{2} (44)\\S_{n} = 9*22\\\boxed{S_{n} = 198}[/tex]

answer:

the answer is 12 pounds

Step-by-step explanation:

Amount of grapes that Johnny has=3.1 pounds

Amount of apples that Johnny has = 6.3 pounds

Total weight of the fruits= 2.6+3.1+6.3=12 pounds

Answer:

a) i) y = - 5/3

  ii) y = 4/3

b) i) x = 1

   ii) x = -3/4

Step-by-step explanation:

[tex]y=\dfrac23x +\dfrac13[/tex]

a) i) [tex]x=-3[/tex]

[tex]\implies y=\dfrac23(-3) +\dfrac13\\\\\\\implies y=\dfrac{-6}{3} +\dfrac13\\\\\\\implies y=\dfrac{1-6}{3} \\\\\\\implies y=-\dfrac53[/tex]

ii) [tex]x=1\frac12=\dfrac32[/tex]

[tex]\implies y=\dfrac23\left(\dfrac32\right) +\dfrac13\\\\\\\implies y=\dfrac{6}{6}+\dfrac13\\\\\\\implies y=\dfrac{3}{3}+\dfrac13\\\\\\\implies y=\dfrac{3+1}{3}\\\\\\\implies y=\dfrac43[/tex]

b) i) [tex]y=1[/tex]

[tex]\implies \dfrac23x +\dfrac13=1\\\\\\\implies \dfrac23x =1-\dfrac13\\\\\\\implies \dfrac23x =\dfrac23\\\\\\\implies x =1[/tex]

ii) [tex]y=-\dfrac16[/tex]

[tex]\implies \dfrac23x +\dfrac13=-\dfrac16\\\\\\\implies \dfrac23x =-\dfrac12\\\\\\\implies x =-\dfrac12 \div \dfrac23=-\dfrac12 \times\dfrac32=-\dfrac34[/tex]

8. 3=3, 6=3*2, 3*2=6, lcm=6

9. 8=2^3, 10=2*5, 2^3*5=40, lcm = 40

10. 3=3, 5=5, 3*5=15, lcm = 15

11. 12=2^2*3, 5=5, 12*5=60, lcm = 60

Answer:

A. x = 212

Step-by-step explanation:

      This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.

[Equation]

x + 122 = 334

[Subtract 122 from both sides]

x = 212

A. x = 212

since volume of rectangular prism is given by V=wlh

the volume of the small cubic blocks is (1/5)^3= 1/125

hence we need 4 of the small cubic blocks.

Answer:

x = 7

Step-by-step explanation:

5x - 1 + 8x + 5 = 95

13x + 4 = 95

13x = 91

x = 7

Triangle in 95° so x is

»8x + 5° + 5x - 1° = 95°

»13x + 4° = 95°

»13x = 91°

»x = 91°/13

»x = 7°✅

[tex]\frac{34}{12}[/tex] , [tex]\frac{51}{18}[/tex] , [tex]\frac{68}{24}[/tex] , [tex]\frac{85}{30}[/tex]

some equivalent fraction examples of [tex]\frac{17}{6}[/tex]:

Therefore the equivalent fractions are [tex]\frac{34}{12}[/tex] , [tex]\frac{51}{18}[/tex] , [tex]\frac{68}{24}[/tex] , [tex]\frac{85}{30}[/tex]

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

Figure A, B, D have point symmetry.

Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).

Try imagining how each of the figure will look after rotating it for 180°.  If it looks exactly same as the original figure, it has point symmetry.
