A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 80 p

ounds. The truck is transporting 70 large boxes and 60 small boxes. If the truck is carrying a total of 5300 pounds in boxes, how much does each type of box weigh?

Large box --> M
Small box --> m

M+m=80
70M+60m=5300

Now solve this system of equations. Very easy job now.

What is the probability that a) A card chosen from an ordinary deck of 52 cards is an ace? b) A randomly selected integer chosen
Gelneren [198K]

Answer:

a) 0.076

b) 0.5

c) 0.084

d) 0.25

e) 0.00024

f) 0.156

Step-by-step explanation:

a) In an ordinary deck there are 4 aces. The probability of getting an ace is given by:

P=\frac{n}{N}

n: options for an ace = 4

N: total number of cards = 52

P=\frac{4}{52}=0.076

The probability is 7.6%

b) On the first 100 positive integers, there are 50 odd integer numbers. Then you have:

P=\frac{50}{100}=0.5

The probability of getting an odd number is 50%

c) From a total of 365 day in the year, May has 31 day. Then you have:

P=\frac{31}{365}=0.084

The probability is 8.4%

d) In this case you have two events. To get an odd number with the sum of the number of two dices you need and odd number in one dice and a pair number in the other dice.

The probability is the product of the occurrence of both events. The probability for an odd number is 1/2 and for a pair number is 1/2.

P=P_{odd}P_{pair}=(\frac{1}{2})(\frac{1}{2})=\frac{1}{4}=0.25

The probability is 25%

e) To obtain Head 6 times in a row, the probability is:

P=\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}=0.00024

Probability of 0.024%

f) To get Head 4 times from 5 flights, you first calculate the probability for 1 head in five flips:

P=(\frac{1}{2})^5=\frac{1}{32}

There are 5 forms of getting 4 Heads for 5 flips, then you have:

P=5(\frac{1}{32})=\frac{5}{32}=0.156

Te probability is 15.6%

Find the LCM of 2 and 10.
taurus [48]

Answer:

10

Step-by-step explanation:

LCM is the Lowest Common multiple.

Since this pair is quite common, we can easily notice that their LCM =  10, because 10 x 1  = 10 and 2 x 5 = 10, and 10 is common in the times tables of both these numbers.

Hope this helps.

Good Luck

Please ark Brainiest.

How do I find the P-value using a chi- square (x2) distribution table?
Nadya [2.5K]
This should be self-explanatory, but just in case it's not: your chi-square score goes in the chi-square score box, you stick your degrees of freedom in the DF box (df = (<span>NColumns-1</span>)*(<span>NRows-1</span>) for chi-square test for independence).
