The simplified value of the expression (4.5 + 7.6) - 8 ÷ 2.5 is 8.9.
PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression (4.5 + 7.6) - 8 ÷ 2.5.
First, we'll solve what's inside the parenthesis.
(4.5 + 7.6) - 8 ÷ 2.5.
= 12.1 - 8 ÷ 2.5.
= 12.1 - 3.2.
= 8.9.

Answer:
The answer is 1.64
Step-by-step explanation:
4.5 + 7.6 = 12.1
12.1 - 8 = 4.1
4.1 ÷ 2.5 = 1.64

Answer: Expected profit is $5,750
Step-by-step explanation:
Given data:
Profit on clear day = $30,000
Profit on a cloudy day = $10,000
Loss when it rains = $5,000
Likelihood = 14%
Sunny = 39%
Solution
First we apply the Expected profit formula
= (30,000*0.14)+(10,000*0.39)+(-5000*0.47)
= $4200 + $3900 + ($2350)
= $8100 + ($2350)
= $5,750
The calculated expected profit is $5,750.
Answer: D, the fourth option.
Step-by-step explanation:
Using proportions, it is found that there are 68 blue tiles.
The rule of three is:
4 blue - 25 total
x blue - 425 total
Applying cross multiplication:
There are 68 blue tiles.
To learn more about proportions, you can check brainly.com/question/24372153
To determine the number of blue tiles used in a pattern, a proportion can be set up with the ratio of red to blue tiles and the total number of tiles. By setting the unknown number of blue tiles as x and cross-multiplying, we find that there are 68 blue tiles used.
To solve how many blue tiles are used, we can set up a proportion based on the given pattern. For every 21 red tiles, there are 4 blue tiles. If a total of 425 tiles are used, we can express this relationship as a fraction:
Red tiles : Blue tiles = 21 : 4
Since the total number of tiles is 425, we can express the unknown number of blue tiles as x. The number of red tiles would then be 425 - x. Our proportion is:
21 / 4 = (425 - x) / x
Cross-multiplication gives us:
21x = 4(425 - x)
Solving for x gives us:
21x = 1700 - 4x
21x + 4x = 1700
25x = 1700
x = 1700 / 25
x = 68
So, there are 68 blue tiles used.

c. Is there convincing evidence that the proportion who make a donation is not the same for the two different methods? Carry out a hypothesis test using a significance level of 0.05.
d. Is there convincing evidence that the proportion who make a donation after receiving an email is smaller than the proportion who make a donation after receiving a text message? Carry out a hypothesis test using a significance level of 0.10.
