Answer:
x = 10
Step-by-step explanation:
I made a right triangle with a leg of 6 (7-1), base of 7, and hypotenuse of 'x' and then used the pythagorean theorem:
6² + 8² = x²
100 = x²
x = √100
x = 10

A university investigation was conducted to determine whether women and men complete medical school in significantly different amounts of time, on the average. Two independent random samples were selected and the following summary information concerning times to completion of medical school computed:
Women Men
Sample size 90 100
Sample mean 8.4 years 8.5 years
Sample std 0.6 year 0.5 years
Required:
Perform the appropriate test to see if there is a significant difference in time to completion of medical school between women and men.

Answer:
Following are the responses to the given question:
Step-by-step explanation:
[tex]Null \ H_{yp}: \mu_{men} = \mu_{women}\\\\Alt \ Hyp: \mu_{men} \neq \mu_{women}\\\\Std\ Error\ (SE) = \sqrt{(\frac{s_1^2}{n_1}) + (\frac{s_2^2}{n_2})} \\\\[/tex]
[tex]= \sqrt{(\frac{0.62}{90}) + (\frac{0.52}{100})} \\\\= 0.08[/tex]
[tex]test\ statistic \ t = \frac{(x_1 - x_2)}{SE} = \frac{(8.4 - 8.5)}{0.08} = -1.25[/tex]
Degrees of freedom
[tex]= \frac{(\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2})^2}{\frac{(\frac{s_1^2}{n_1})^2}{(n_1 - 1)}} + \frac{(\frac{s_2^2}{n_2)^2}}{(n_2 - 1)} \\\\= 174[/tex]
Considering a degree of 5% importance
T for df critical value = 174 and sig level = 0.05 is +1.973
Let area of refusal shall be t < -1.973 or t > +1.973
Because statistical tests weren't in the refusal zone, they may not deny that zero but find that perhaps the argument how both women and men undergo med school is considerably different lengths of time is not significantly supported.
What number should be added to both sides of the equation to complete the square?
x2 - 6x = 5
Answers
Answer:
Ans: 9
pls mark as brainliest!!
Step-by-step explanation:
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
x^2 – 6x = 5
2. Make sure that the coefficient of the x^2 term is 1.
x^2 – 6x = 5
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
x^2 – 6x + 9 = 5 + 9
(x-3)^2 = 14
Therefore, 9 should be added to both sides to complete the square.

72^2+b^2 = 78^2
5184+b^2 = 6084
b2 = 900
b = 30
Answer:
b = 30 km is the answer
Step-by-step explanation:
a = 72 km
b = ?
c = 78 km
According to the Pythagoras theorem,
a² + b² = c²
72² + b² = 78²
5184 + b² = 6084
b² = 6084 - 5184
b² = 900
b = 30 km

a. m MUC - m MUP = m PUC
b. m DUC + m VUA = m DUV
C. m MUC = m MUV = m VUA = m AUD
d. m CUA + m DUP = m PUM
Answers
Answer:
a. m<MUC - m<MUP = m<PUC
Step-by-step explanation:
From the options given, the only statement that is true of the figure shown is:
a. m<MUC - m<MUP = m<PUC
Rationale:
m<MUC = m<MUP + m<PUC (Angle Addition Postulate)
Subtract m<MUP from each side
m<MUC - m<MUP = m<PUC

What is spherical triangle?This spherical triangle is indeed a shape created on a sphere's surface by three. The spherical triangle is indeed a shape created on a sphere's surface by three large circular arcs coming together pairwise at its three vertices.
The spherical triangle, which is frequently referred to as an Euler triangle when three of its vertices are intersected pairwise by circular arcs, is the spherical equivalent of the planar triangle. The spherical triangle, also known as an Euler triangle, is the spherical equivalent of the planar triangle. A triangle on a sphere could have 220 degrees.
