After 36 min , first alarm will ring 4 times (36=4*9) and the second alarm 3 times (36=3*12)
6.45- 6.54- 7.03- 7.12- 7.21   
6.45- 6.57- 7.09- 7.21

At 7.21 will ring together

Misty has several pieces of construction paper that each measure 4 inches long and 9 inches wide. She needs to create the smalle
solniwko [45]

We are given that the dimensions are 4 in x 9 in. To get the smallest possible square, first let us find for the LCM of 4 and 9.

4 = 0, 4, 8, 12, 16, 20, 24, 28, 32, 36

9 = 0, 9, 18, 27, 36

We can actually see that 36 is the least common multiple.

Therefore the smallest possible square has a dimension of:

Can somebody who knows how to do probability please help answer these questions correctly? Thanks! (Btw the P= probability)
stira [4]

Answer:

P(2): 1/5

P(4): 1/5

P(odd number): 3/5

P(whole number): 5/5

P(6): 0/5

P(2 or 3): 2/5

Step-by-step explanation:

There are 5 <em>equal </em>sections in this circle. So, the probability to land in each section is 1/5.

The odd numbers are 1, 3, and 5. Since each section is 1/5, you add

1/5 + 1/5 + 1/5 = 3/5. That is the probability that you will land in any odd number.

Because all the numbers listed are whole numbers, no matter where the spinner lands it will be a whole number. So, the probability is 5/5 for whole numbers.

Since 6 is not a section, it's probability will be 0/5 (or you can just put 0).

"Or" means you add the two probabilities. Add the probability of landing on 3 (which is 1/5) to the probability of landing on 2 (which is also 1/5). So, you get 2/5.

A real estate builder wishes to determine how house size is influenced by family income, family size, and education of the head
OlgaM077 [116]

Answer:

see explaination

Step-by-step explanation:

1) Lets form the regression equation from the data results

Size = -1.633+ 0.4485*FamilyIncome + 4.2615*FamilySize - 0.6517*Education

-1.633+ 0.4485*40+ 4.2615*4 - 0.6517*13 =24.88

2) For the model to be reasonable, we must check the significant F stat from the anova table( see attachment)

From the table at attachment we can deduce; as the significant F is less 0.01 , we can safely conclude that the model is signifcant

3) all variables that have a p value less than 0.01 can be safely removed from the model as they do not contribute sigificantly from the model

so education can be removed from the model

G<br> If f(x) = 6x – 4, what is f(x) when x = 8?
I am Lyosha [343]

Answer: f(x)=44

Step-by-step explanation:

Since x is given, we can directly plug it into our function.

f(8)=6(8)-4

f(8)=48-4

f(8)=44
