Answer:

3*45=135 minutes.

Step-by-step explanation:

Hello there!

Start by seeing if there is an equal rate in the qmount of people that we are working with.

27/9=3 (so there's one)

3*45 (the amount of time when 9 people are in line)= 135 minutes

Have a great day!

Choose a number between and that is a multiple 45 of and 95 . Write all the numbers that she could choose. If there is more than

AnnZ [28]

Answer with explanation:

To find the common multiple of 45 and 95,we will find HCF of 45 and 95.

45=3 × 3× 5

95=5 × 19

⇒H CF(45,95)

=3 × 3×5×19

=855

→Common multiple of 45 and 95 =855

→There are infinite number of multiple of 855 which are 855, 1710, 2565,.....

You have not written between which two numbers.So, you should write multiple of 855 such that it is smaller than the greater number.

Motorola used the normal distribution to determine the probability of defects and the number of defects expected in a production

Lena [83]

The question supplied is incomplete :

The x parameters aren't given ; "Units with weights less than or greater than ounces will be classified as defects"

Assume the unit weights Given are ;

Units with weights less than 10.8 or greater than 11.2 ounces will be classified as defects

Just follow the procedure in the solution for any value of unit weight interval given.

Answer:

0.3173

Step-by-step explanation:

Mean weight, m = 11 ounces

Standard deviation, s = 0.2 ounces

Find the Zscore for each unit weight :

Z = (x - mean) / standard deviation

P(x < 10.8) :

Z = (10.8 - 11) / 0.2 = - 1

P(Z < - 1) = 0.15866

P(x > 11.2) :

Z = (11.2 - 11) / 0.2 = 1

P(Z > 1) = 0.84134

P(x < 11.2) - P(x < 10.8) = 1 - (P(Z < 1) - P(Z < - 1)) = 1 - 1 - (0.84134 - 0.15866) = 1 - 0.68268 = 0.31732

Hence, Probability of a defect is 0.3173

Can u please answer this question

One Way:
We can change the mixed number to a decimal for comparing.

$1\frac{1}{4}$ m = $\frac{5}{4}$ m = 1.25 m

1.4 m    > 1.25 m
Darren   >   Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

$1\frac{1}{4}$ = $\frac{5}{4}$ (Luke)
1.4 = $\frac{7}{5}$ (Darren)
We need a common denominator to compare
$\frac{5*5}{4*5}$ (Luke)
$\frac{7*4}{5*4}$ (Darren)
$\frac{25}{20}$ (Luke)
$\frac{28}{20}$ (Darren)

$\frac{28}{20} > \frac{25}{20}$
  Darren >    Luke

By:
$\frac{28}{20}$ - $\frac{25}{20}$ = $\frac{3}{20}$
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
