2x - 1 = 17...............
Answer:
x = 9
Step-by-step explanation:
2x - 1 + 1 = 17 + 1
2x = 18
(2x=18)/2
x = 9
Answer:
2x - 1 = 17
add 1 on each side --> 2x = 18
x = 9 because one divides 2 from each side and results to 9

I need help solving for x
Answer:
[tex]x=63.0^o[/tex]
Step-by-step explanation:
Given
[tex]RS = 35[/tex]
[tex]RT = 77[/tex]
The attached triangle
Required
Solve for x
The relationship between x, RS and RT is:
[tex]\cos(x) = \frac{RS}{RT}[/tex]
This gives:
[tex]\cos(x) = \frac{35}{77}[/tex]
[tex]\cos(x) = 0.4545[/tex]
Take arc cos of both sides:
[tex]x = \cos^{-1}(0.4545)[/tex]
[tex]x=63.0^o[/tex] --- approximated

In the triangle below, what is the cosine of 45°? Someone please help ASAP
Answer:
B. 1/√2
Step-by-step explanation:
Soh Cah Toa
cos is adjacent over hypotenuse so from either 45° degree angle it is 1/√2
For the given right angle triangle, cos 45 = 1/√2
Hence, option B is correct.
In the given triangle,
Adjacent = 1
Hypotenuse = √2
Since we know,
The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
For a right angled triangle,
Cosθ = adjacent / hypotenuse
Therefore,
cos 45 = 1/√2

Identify the cavity that develops entirely from the mesoderm.
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
50,20,8
Find the 8th term.
Answer:
.082
Step-by-step explanation:
First find the common ratio
Take the second term and divide by the first term
20/50 = 2/5 = .4
Check with the third term divided by the second term
8/20 = .4
The formula for a geometric sequence is
an = a1 (r) ^(n-1) where a1 is the first term and r is the common ratio
=50 ( .4) ^ (n-1)
We want to find the 8th term
= 50 ( .4)^(8-1)
= 50 ( .4) ^7
=0.08192
Round to the nearest thousandth
= .082

Fifty percent of the customers who go to Sears Auto Center for tires buy four tires and 30% buy two tires. Moreover, 18% buy fewer than two tires, with 5% buying none.
a. What is the probability that a customer buys three tires?
b. Construct a cumulative probability distribution for the number of tires bought.
Answer:
A. Probability = 0.02
B. This is in a cumulative frequency table in the attachment I added
Step-by-step explanation:
A. We have these following probabilities
Prob(X=0) = 0.05
Prob(x= 2) = 0.30
Prob(X = 4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1)
0.18 = 0.05 + prob(X=1)
prob(X=1) = 0.13
A. Prob(x = 3)
= 1 - (0.05 + 0.13 + 0.30 + 0.50)
= 0.02
Probability of buying only 3 times = 2%
B. The cumulative frequency is in the attachment.
10 1/16ft + 8 3/8ft +1/2 ft
Answer:
18 15/16 ft
Step-by-step explanation:
what is the request here ?
to do the additions and bring all to one summary result of ft ?
I base my answer on this assumption.
10 1/16 = 161/16
8 3/8 = 67/8
1/2 = 1/2
note let's bring everything to 16th, so that we can actually add them.
161/16
67/8 = 134/16
1/2 = 8/16
161/16 + 134/16 + 8/16 = 303/16 = 18 15/16
cross check :
add all whole numbers first, and then add the remaining fractions too (need to bring them to 16th too).
10 + 8 = 18
1/16 + 3/8 + 1/2 = 1/16 + 6/16 + 8/16 = 15/16
together, 18 15/16

if gh¢400.00 is deposited at a bank at 10% per annum compounded quarterly, how long will it take the deposit to double it value.
9514 1404 393
Answer:
7 years
Step-by-step explanation:
The multiplier each quarter is 1 +10%/4 = 1.025. The number of quarters, n, that must pass before the value is multiplied by 2 is given by ...
1.025^n = 2
Taking logarithms, we can solve for n:
n×log(1.025) = log(2)
n = log(2)/log(1.025) ≈ 28.071
It will take 28 quarters, or 7 years, for the value to double.

Answer:
x = 41.05
Step-by-step explanation:
Given that,
In a right angles triangle,
Perpendicular height, P = 228
Angle 1 = 90°
Angle 2 = 47°
Angle 3 = 180-(90+47) = 43°
Using trigonometry to find x.
[tex]\sin\theta=\dfrac{P}{x}\\\\x=\dfrac{P}{\sin\theta}\\\\x=\dfrac{28}{\sin(43)}\\\\x=41.05[/tex]

What are the coordinates of point (6,-2) after D o, 1/2
Explanation: Cut each coordinate in half.
In other words, multiply each coordinate by 1/2 = 0.5
6*0.5 = 3
-2*0.5 = -1
The point (6,-2) moves to (3, -1) after the dilation. This trick only works because the origin is the center of dilation.

Suppose one relatively large value is added to a set of all relatively small data values. Which of the following measures would not be affected (i.e. 10 12 16 12 150 13 - which average technique would not be impacted by the outlier)?
A. the mode.
B. the standard deviation.
C. the range.
D. the mean.
Answer:
A. the mode.
Step-by-step explanation:
Mean
Sum of all values divided by the number of values, so is affected by an outlier present in the data-set.
Standard deviation:
Square root of the sum of the differences squared between each value and the mean, divided by the sample size. As it's related to the mean, it is affected by an outlier.
Range:
Subtraction of the largest value of the data-set by the smallest value, and thus, is also affected by an outlier.
Mode
Value that appears the most often in the data-set, and thus, not affected by an outlier, which means that the correct answer is given by option A.
