Answer:

points S and T

Step-by-step explanation:

The vertices are the endpoints of the major axis, the axis through the foci, which are points N and P for this ellipse.

Answer:

The correct option is 4. Points S and T are the vertices of the ellipse.

Step-by-step explanation:

The end points of the major axis are called vertices of the ellipse and the end points of minor axis are called co-vertices.

The standard form of an ellipse is

$\frac{x^2}{a^2}+\frac{y^2}{b^2}=1$

If a>b, then vertices are (± a,0) and co-vertices are (0, ± b).

If a<b, then vertices are (0, ± b) and co-vertices are (± a,0).

From the given figure it is clear that major axis is ST and minor axis is QR. So, points S and T are vertices and points Q and R are co-vertices of the ellipse.

Since the end points of the major axis are called vertices of the ellipse, therefore the point S and T are the vertices of the ellipse.

Answer:

Note: The full question is attached as picture below

a) Hо : p = 0.71

Ha : p ≠ 0.71

p = x / n

p = 91/110

p = 0.83.

1 - Pо = 1 - 0.71 = 0.29.

b) Test statistic = z

= p - Pо / [√Pо * (1 - Pо ) / n]

= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]

= 0.12 / 0.043265

= 2.77360453

Test statistic = 2.77

c) P-value

P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028

P-value = 0.0056

∝ = 0.01

P-value < ∝

Reject the null hypothesis. There is sufficient evidence to support the researchers claim at the 1% significance level.

I will give u brianliest

Bond [772]

Answer:

1: $3$ × $2$

2: $y^6$

Step-by-step explanation:

Multiply the numbers: $y(^3^*^2)$

$3*2 = 6$

Write it without exponents:

$y * y * y * y *y *y$ so $6y$ .

$(y^3)^2$

Apply exponent rule : $(a^b)^c=a^b^c,$ assuming $a\geq 0$

$(y^3)^2=y^3^*^2$

$=y^3^*^2$

Multiply the numbers: $3 * 2 = 6$

$= y^6$

Hope I helped! If so, may I get Brainliest and a Thanks?

Thank you, have a good one! =)

Anyone got the answers for b and c

BaLLatris [955]

For letter b:

First times 5 on both sides to get rid of the denominator of 5

5 * y
— = 4 * 5
5

Then the answer is

y = 20

For letter c:

First move constants on one side, variables on the other

2g = 17 - 8

Then collect like terms:

2g = 9

Then divide both sides which would equal:

g = 9/2
