Andrei weighs 32 kg, which is 4/7 of the weight of his older sister and 2/5 of the weight of his father. The mother’s weight is

7/8 of the father’s weight. Can they all, together, go into an elevator that can hold 300 kg if they also have to take their 17 kg dog?

Answer:

Yes.

Step-by-step explanation:

Andrei weighs 32 kg.  This is 4/7 of his sister's weight; this means his sister weighs

7/4(32) = 56 kg.

32 kg is 2/5 of his father's weight; this means his father weighs

5/2(32) = 80 kg.

His mother weighs 7/8 of his father's weight; this means his mother weighs

7/8(80) = 70 kg.

Together they weigh

32+56+80+70 = 238.

With his dog, they weigh

238+17 = 255 kg.

This means they can all go into the elevator.

A random sample of 420 new Ford trucks showed that 105 required repairs within the first warranty year.What is the estimate for
zvonat [6]
The probability of an event P(n), is equal to the number of the outcomes of that event n(E), divided by the total number of outcomes, or the sample space, n(S)

so P(n)= \frac{n(E)}{n(S)}


P(truck need rapair within the first year)=

\frac{n(truck need rapair within the first year)}{n(trucks)} = \frac{105} {420}= 0.25

The probability of an event = 1 - probability of the same event not to happen

so P(not need repair within the first year)=1-0.25=0.75


Answer: a) 0,25; b) 0,75

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam. Find
natta225 [31]

The tension in the cable is given by the newton's first law will be 163.622 N.

<h3>What is newton's first law?</h3>

The summation of the force is equal to zero.

The formula is given as

ΣF = 0

Where m is the mass of the body and a is the acceleration.

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam.

Then the tension in the cable will be

Let T be the tension in the cable.

T sin 29° + T sin 53° – 210 = 0

On simplifying, we have

T (sin 29° + sin 53°) = 210

                             T = 163.622 N

Given the sets A = {-4, -1, 3, 5, 9} and B = {-2, -1, 0, 1, 2, 3}, the set AUB (u is upside down) is given by:
ki77a [65]

The upside down U is the symbol for the intersection of sets. The intersection of two sets is the set that contains the elements that are common to both sets. Which elements are both in set A and in set B?

Answer: {-1, 3}
