4.5m is ____ % of 90 cm; 90 cm is ____ % of 4.5m

Mathematics
1 answer:
Burka [1]2 years ago
4 0

Answer: 5%

Step-by-step explanation:

Firstly, Convert metre to centimetre

100cm = 1m

Therefore,

4.5m = 450cm

If 450cm is X% of 90cm

That becomes :

450= X% × 90

450= 90X%

X% = 450/90

X% = 5%

A four-sided die is rolled repeatedly, until the first time (if ever) that an even number is obtained. What is the sample space
Andrew [12]

Answer:

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

Therefore, the sample space for this experiment rolling a four-sided die will be: {1, 2, 3, 4}

Step-by-step explanation:

When you roll a a four-sided die, number of dots on uppermost face is said to be an outcome.

For example,  whenever a four-sided die is rolled we can get either 1, 2,3 or 4 dots on the upper most face as an outcome.

As we know that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Possibilities of the number being even (2 and 4) = 2

Probability of the number being even = 2/4 = 1/2

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

As we have already determined that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Therefore, the sample space for this experiment will be: {1, 2, 3, 4}

Keywords: sample space, 4-sided dice

At a certain company, loan agents are paid based on the number of loans they close in a day. Based on company records, the numbe
Ilya [14]

Answer:

C. The mean daily salary is greater than $350 per day

Step-by-step explanation:

The computation is shown below:

Y = a + bX

where,

Y = money made by a random selected

a = $150

b = $50

X = number of loan

Now

E(x) = (1 × 0.05) + (2 × 0.10) + (3 × 0.22) + (4 × 0.30) + (5 × 0.18) + (6 × 0.12) + (7 × 0.03)

= 3.94

Now

E(y) = $150 + ($50 × 3.94)

= $347

hence, the option C is not correct

In a USA TODAY/Gallup Poll, respondents favored Barack Obama over Mitt Romney in terms of likeability, 61% to 32% (Los Angeles T
dybincka [34]

Answer:

a) percentage of respondents that favored neither Obama nor Romney in terms of likeability = 7%

b) For a given survey of 500, the number of respondents that favored Obama than Romney is 145.

Step-by-step explanation:

Given that none of those surveyed can favour the two candidates at the same time,

n(Universal set) = n(U) = 100%

n(Obama) = n(O) = 61%

n(Romney) = n(R) = 32%

n(That favour Obama and Romney) = n(O n R) = 0%

To calculate for the number that favour neither of the candidates

n(O' n R')

n(U) = n(O) + n(R) + n(O n R) + n(O' n R')

100 = 61 + 32 + 0 + n(O' n R')

n(O' n R') = 100 - 93 = 7%

b) For a given survey of 500, how many more respondents favored Obama than Romney?

Number of those surveyed that favour Obama = 61% of 500 = 305

Number of those surveyed that favour Romney = 32% of 500 = 160

Difference = 305 - 160 = 145

Cindy found a collection of baseball cards in her attic worth $8,000. the collection is estimated to increase in value by 1.5% p
Sergio [31]
A]
Exponential function is given by the form:
y=a(b)ˣ
where:
a=initial value
b=growth factor
From the question:
a=$8000, b=1.015, 
thus the exponential growth function of this situation is:
y=8000(1.015)ˣ

b] The value of the collection after 7 years will be:
x=7 years
Using the formula:
y=8000(1.015)ˣ
plugging the values we get:
y=8000(1.015)⁷
y=8,878.76

Answer: $8,878.76
