Explain how you can use a 10 by 10 grid to model 42%

Mathematics
1 answer:
tia_tia [17]2 years ago

a 10-by-10 grid means there are 100 squares and percent is out of 100 so if you have 42% then you just need to fill in 42 squares

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f
IgorLugansk [536]
Use the equation of motion under gravity:-

s =  16t^2    where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 =  128.94 s

t = sqrt 128.94  =  11. 4 seconds to the nearest tenth of a second

I need to know x . if you could also explain that would be nice
defon

Answer:

x = 7.5

Step-by-step explanation:

Since the midsegment and the third segment of the triangle are parallel to each other, therefore,

\frac{8 + 10}{8} = \frac{6 + x}{6}

\frac{18}{8} = \frac{6 + x}{6}

\frac{9}{4} = \frac{6 + x}{6}

Cross multiply

9*6 = 4(6 + x)

54 = 24 + 4x

Subtract 24 from each side

54 - 24 = 4x

30 = 4x

Divide both sides by 4

30/4 = x

7.5 = x

x = 7.5

Can someone explain number five??
vazorg [7]

Remark

You have 40 dollars to spend.

<em><u>AT & T</u></em>

Let the number of minutes = M

A. 20 + 0.10*M ≤ 40  

B. 20 + 0.10*M ≤ 40     Subtract 20 from both sides.

20 - 20 + 0.10M ≤ 40 - 20

0.10M ≤ 20                   Divide by 0.10

0.10M/0.10 ≤20/0.10

M≤ 200 minutes.

Verizon

A

15 + ( M ≥ 300)*0.50 ≤ 40

B

15 + ( M ≥ 300)*0.50 ≤ 40                   Subtract 15 from both sides.

(M≥300)*0.50 ≤ 25

(M≥300) ≤ 50 minutes.

This last one is a good deal more complicated. What it means is that if you are under 300 minutes, you pay only 15 dollars. If you are over 300 minutes, you can only go 50 more minutes before over extend your budget.

Part  C

These are alike in that they have a flat rate associated with them and both have a budgeted amount that has to be obeyed.

They are quite different in what they offer. The second plan is for people who use their cell phone quite a bit. For people like us (emergency only), the first plan is much better. We would always be within our 40 dollar limit. We don't use our cell but maybe 10 - 15 minutes a month on average.

Part D

I can't answer this for you. It depends on where you live and who offers you the best coverage. I would pick the first one, but that doesn't mean that it would be best for you.

A consumer organization that evaluates new motorcycles customarily reports the number of major defects in each motorcycle examin
koban [17]

Answer:

a) F(2)=0.30

b)P(X>3)=0.7

c)P(2≤X≤5)=0.67

d)P(2<X<5)=0.71

Step-by-step explanation:

a) F(2)=P(X≤2)=0.30

F(2) is given in the probability distribution

b) P(X>3)=1-P(X≤2)=1-F(2)=1-0.3=0.7

P(X>3)=0.7

c)P(2≤X≤5)=?

As we know that P(a≤X≤b)=F(b)-F(a)=P(X≤b)-P(X≤a)

So,

P(2≤X≤5)=P(X≤5)-P(X≤2)=F(5)-F(2)=0.97-0.3=0.67

P(2≤X≤5)=0.67

d)P(2<X<5)=P(1≤X≤4)=P(X≤4)-P(X≤1)=F(4)-F(1)=0.91-0.2=0.71.

P(2<X<5)=0.71
