The shortest possible height of tower is 24 cm.

Tim used 4 blue blocks and his brother used 3 green blocks.

Step-by-step explanation:

Given,

Height of blue block = 6 cm

Height of green block = 8 cm

We will take least common multiple to find the shortest possible height.

6 = 2*3

8 = 2*2*2

LCM = 2*2*2*3 = 24 cm

The shortest possible height of tower is 24 cm.

Number of blue blocks used = \frac{24}{6} = 4

Number of green blocks used = \frac{24}{8} = 3

Tim used 4 blue blocks and his brother used 3 green blocks.

To obtain an estimate of the proportion of "full time" university students who have a part time job in excess of 30 hours per we
musickatia [10]

Answer:

2,436 students

Step-by-step explanation:

At a 90% confidence level, the z-score is 1.645 and the confidence interval is given by:

x\pm z\frac{s}{\sqrt n}

Where s is the standard deviation, and  n is the sample size.

If they want the length of their confidence interval to be no greater than 0.2, it must be no further than 0.1 from the mean 'X':

0.1>1.645\frac{3}{\sqrt n}\\\sqrt n>1.645*30\\n>2,435.42

Rounding up to the next whole number, the sample size should be 2,436 students.

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings
Sophie [7]

Answer:

the experimental probability is 70%

Step-by-step explanation:

PLEASE HELP, TIMEDThe table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they have.

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings?

To the nearest whole percent, the experimental probability is

a. 65%.

b. 70%

c. 75%

d. 80%

We are given to find

the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

we know that

probability = ( number of favourable outcomes)/ ( total possible outcomes)

a 10th-grade student chosen at random has at least one, but no more than two, siblings

so, there can be one or two siblings

so, total number of such students =18+10=28

Number of favourable outcomes =28

total number of students =4+18+10+8=40

so, total favourable outcomes =40

now, we can find probability

p=\frac{28}{40}\\\\p=\frac{28}{40}\times 100\\\\p=70

So,

Therefore, the experimental probability is 70%
