Answer: You must rearange 3 3/4 into an improper fraction to make the subtraction easier.
Step-by-step explanation:
(this is a little long bear with me :3)
3 and 3/4ths into a improper fraction would be: 15/4
looking at 15/4 and 7/8 notice how the denominators are 4, and 8. both are common denominators. so we multiply 4x2 to make 4, into 8. and whatever we do to the bottom, we do to the top.
15x2 30
---------- = ------
4x2 8
our new fraction is 30/8.
do the subtraction..
30 7 23
---- - --- = --- that then turns into a mixed number, which is:
8 8 8
2 7/8.

On a coordinate plane, triangles A B C and D E F are shown. Triangle A B C has points (negative 10, negative 10), (negative 10, negative 4), and (4, negative 10). Triangle D E F has points (0, 8), (12, 4), and (5, 0). Which statement is true of the right triangles ABC and DEF? Area of ABC is greater than area of DEF. Area of ABC is less than area of DEF. Area of ABC is equal to the area of DEF. There is not enough information to compare the areas of triangles ABC and DEF.
Answer:
Area of ABC is greater than area of DEF
Step-by-step explanation:
Answer:
A. Area of ABC is greater than area of DEF.
A phone company plans on offering their new smartphone in four colours: white, black, silver and rose gold. They anticipate that 30% of shoppers will prefer white, 35% will prefer black, 20% will prefer silver and 15% will prefer rose gold. They perform market research by asking a random sample of 350 potential customers which colour they prefer.
Color White Black Silve Rose Gold
Frequency 99 135 89 27
Can the company conclude that their expected distribution was accurate using a 10% level of significance?
a. Calculate the test statistic.
b. Determine the critical value(s) for the hypothesis test.
c. Conclude whether to reject the null hypothesis or not based on the test
a)
The test statistics is χ² = 8.31
b)
The critical value is 6.251.
c)
We reject the null hypothesis that the expected distribution is accurate.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
a.
To test whether the expected distribution was accurate, we need to perform a chi-square goodness-of-fit test.
The null hypothesis is that the expected distribution is accurate, and the alternative hypothesis is that it is not accurate.
The expected frequencies are:
Color:
White Black Silver Rose Gold
105 122.5 70 52.5
i.e
Expected Freq:
0.3 x 350 = 105
0.35 x 350 = 122.5
0.2 x 350 = 70
0.15 x 350 = 52.5
Using the formula for the chi-square goodness-of-fit test statistic:
χ² = ∑ (Observed Frequency - Expected Frequency)² / Expected Frequency
χ² = [(99-105)²/105] + [(135-122.5)²/122.5] + [(89-70)²/70] + [(27-52.5)²/52.5]
χ² = 8.31
b.
The critical value for the chi-square test with 3 degrees of freedom (4 categories - 1) and a significance level of 0.10 is 6.251.
c.
Since the calculated test statistic (8.31) is greater than the critical value (6.251), we reject the null hypothesis that the expected distribution is accurate.
Therefore, the company cannot conclude that their expected distribution was accurate using a 10% level of significance.
Thus,
a)
The test statistics is χ² = 8.31
b)
The critical value is 6.251.
c)
We reject the null hypothesis that the expected distribution is accurate.

Answer:
volume: 200 cm³surface area: 220 cm²Step-by-step explanation:
The usual formulas are useful for this.
V = LWH
V = (10 cm)(4 cm)(5 cm) = 200 cm³
The volume is 200 cubic centimeters.
__
SA = 2(LW +H(L +W))
SA = 2((10 cm)(4 cm) +(5 cm)(10 cm +4 cm)) = 2(40 +5(14)) cm² = 220 cm²
The surface area is 220 square centimeters.

Answer:
80?
Step-by-step explanation:
Answer:
80 white candles
Step-by-step explanation:
I use a way that makes it easy for me
2:5 means [tex]\frac{2}{5}[/tex]
so when you write [tex]\frac{2}{5} =[/tex][tex]\frac{32}{x}[/tex]
that means you do the cross multiplication method which makes the equation go that way:
[tex]2x=32*5[/tex]
so
[tex]2x=160\\x= 80[/tex]
