Answer:

t=\frac{1}{2}

Step-by-step explanation:

We want to solve for the value of t in the equation

4(t+\frac{1}{4})=3

Since we are trying to make t the subject of the formula (or isolate t)

Divide both sides by 4

\dfrac{4(t+\frac{1}{4})}{4} =\dfrac{3}{4}

This gives us:

t+\frac{1}{4} =\frac{3}{4}

Next, we subtract \dfrac{1}{4} from both sides

t+\frac{1}{4}-\frac{1}{4} =\frac{3}{4}-\frac{1}{4}\\t=\dfrac{3-1}{4}=\frac{2}{4}=\frac{1}{2}\\t=\frac{1}{2}

Emma ⇒ IQR = 3.5

Sally ⇒ IQR = 3

Olivia ⇒ IQR = 2.5

Emma - Sally - Olivia

Step-by-step explanation:

Emma's Scores:

<u>6 , 7 , 8 , 8 , </u><u>9 , 9</u><u> , 9 , 10 , 10 , </u><u>11</u> , <u>11</u><u> , 11 , 11 , 11 , </u><u>12 , 13</u><u> , 13 , 13 , 13 , 14</u>

LQ = (9 + 9) ÷ 2 = 9

UQ = (12 + 13) ÷ 2 = 12.5

IQR = 12.5 - 9 = 3.5

Sally's Scores:

<u>6 , 6 , 6 , 7 , </u><u>7 , 8</u><u> , 8 , 8 , 9 , </u><u>9</u> , <u>10</u><u> , 10 , 10 , 10 , 10</u><u> , 10 , 11</u><u> , 11 , 12 , 12 , 14</u>

LQ = (7 + 8) ÷ 2 = 7.5

UQ = (10 + 11) ÷ 2 = 10.5

IQR = 10.5 - 7.5 = 3

Olivia's Scores:

The weight of a USB flash drive is 30 grams and is normally distributed. Periodically, quality control inspectors at Dallas Flas
vazorg [7]

Answer:

The critical t values are -1.746 and 1.746.

Step-by-step explanation:

Given information:

The weight of a USB flash drive is 30 grams and is normally distributed.

Population mean = 30

Sample size = 17

Sample mean= 31.9

Standard deviation = 1.8

Significance level, α=0.10

Null hypothesis: H_0:\mu=30

Alternative hypothesis: H_1:\mu\neq 30

It is a two tailed test.

The t-critical values for a two-tailed test, for a significance level of α=0.1 are  -1.746 and 1.746.

Therefore the critical t values are -1.746 and 1.746.

What fraction of 30 is 12
zloy xaker [14]

Call the mystery fraction ' F ' (for 'fraction').

12 is the mystery fraction of 30 .

                                             12  =  F x 30

Divide each side by  30 :      F  =  12/30  =  2/5 .
