Answer:
d. tan (35) = [tex]\frac{x}{10}[/tex]
Step-by-step explanation:
You must memorize the definitions of all the trig functions.
Tan of an angle = opposite side/adjacent side
In your case, the opposite side of the 35° angle is x and the adjacent side of the 35° angle is 10
So, tan 35 = x/10

The ratio of green to white candles is 2:5. If there are 32 green candles, how many white candles are there?
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]

Answer: x=10, is the correct answer.
Step-by-step explanation:
Solve the proportion 3/x+1 = 1+2
Answer:
x = 5
Common denominator of 3/x+1 to 1/2
If the numerator is 3 times, then so is the denominator in a proportion.
3/1=x+1/2
x+1 must equal 6 for the proportion to be equal to 1/2.
6-1=5, so x is 5.

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.

In triangle XYZ, the measure of angle Z is 42°, and the measure of angle Y is 68.4°. What is the measure of angle X?
9514 1404 393
Answer:
69.6°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle X is ...
∠X = 180° -∠Y -∠Z
∠X = 180° -68.4° -42°
∠X = 69.6°

for what value of x is the equation below true?
x2+4x +5=0
Hi there!
[tex]\large\boxed{\text{None.}}[/tex]
Using the discriminant formula, we can determine if this equation is ever true:
b² - 4ac
Plug in the a, b, and c values from the equation:
(4)² - 4(1)(5)
16 - 20 = -4 < 0
Since the discriminant is less than 0, there are no zeros to the equation. Thus, the equation is never true.
