Answer:
x = 100 degrees
Step-by-step explanation:
There are 360 degrees total in this figure. Since 160 is already shown, we can subtract it from 360 to solve for x. 360 - 160 = 200. So, 200 degrees is split among the remaining values, which are 2 x's. Since each x has the same value, we can divide 200 evenly among the two of them. 200/2 = 100. So, x = 100.
P.S.: Sorry if this is long-winded, I haven't taken geometry in a while. I hope I explained it well enough for you and other Brainly users.
Square root means 46225^1/2 so the answer is 65
Answer and Step-by-step explanation: Scaterplot is a type of graphic which shows the relationship between to variables. In this question, you want to determine if there is a linear relationship between overhead widths of seals and the weights. So, the hypothesis are:
H₀: no linear correlation;
H₁: there is linear correlation;
In this hypothesis test, to reject H₀, the correlation coefficient r of the data set has to be bigger than the critical value from the table.
With α = 0.05 and n = 6, the critical value is 0.811.
The linear correlation is calculated as:
r = n∑xy - ∑x.∑y / √[n∑x² - (∑x)²] [n∑y² - (∑y)²]
r = 
r = 0.9485
Since r is bigger than the critical value, H₀ is rejected, which means there is enough evidence to conclude that there is linear correlation between overhead widths and the weights.
In the attachments is the scaterplot of the measurements, also showing the relationship.
Answer:
can't see that
Step-by-step explanation:
Solve the equation for x, where x is restricted to the given interval. y= 8 cos 3x, for x in[0, pi/3] x = 1/3 y/8 x= 1/8 y/3 x= 5 y/3 x= 3 y/8 Use a calculator to give the value to the nearest degree. theta - sin^-1(0.8830) 57 degree 62 degree 60 degree 118 degree Write the product as a sum or different of trigonometric functions. 2 sin 2x sin 12 x cos 14x + cos 10x 1/2(cos 14x + cos 10x) sin 14x + sin 10x cos 10x - cos 14x Find the value of the real number y. y = cos^-1[squarerrot 2/2] pi/4 11 pi/6 7 pi/4 pi/6 Use Identities to find the exact value. cos 165 degree - squareroot 6 - squareroot 2/4 squareroot 2 - squareroot 6/4 squareroot 6 - squareroot 2/4 squareroot 6 + squareroot 2/4
