Elenna [48]

Answer:

The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.

Step-by-step explanation:

Let's find an alternate hypothesis by using the formula:

mean=(sum of all data)/(number of data points) so:

sum of all data=9.0+7.3+6.0+8.8+6.8+8.4+6.6=52.9 and:

number of data points=7 so:

mean=52.9/7=7.56 pounds

The alternate hypothesis is that newborn infants has a mean weight of 7.56 pounds.

Sin law or cos law?!!!!!!!!!!!!! ​
MA_775_DIABLO [31]

Answer:

Law of Sines

Step-by-step explanation:

Law of Sines: \frac{A}{sina} =\frac{B}{sinb} =\frac{C}{sinc}

Step 1: Solve for m∠B

\frac{25}{sin36} =\frac{27}{sinx}

25sinx = 27sin36°

sinx = 27sin36°/25

x = sin^{-1}(\frac{27sin36}{25} )

m∠B ≈ 39.4°

Step 3: Find m∠C

180 - (36 + 39.4)

180 - 75.4

m∠C = 104.6°

Can someone please help me in this question
Pie

Step-by-step explanation:

a) Let y = f(x) = 3x - 2x^2

f(-2) = 3(-2) - 2(-2)^2 = p

= -6 - 8

= -14

= p

f(2.5) = 3(2.5) - 2(2.5)^2 = q

= 7.5 - 12.5

= -5

= q

b) graphing

c) From the graph, you should be able to verify the following:

i) f(0.5) = 3(0.5) - 2(0.5)^2 = 1

ii) 0.5 = 3x - 2x^2 or x = 1.3, 0.2

iii) the maximum occurs at

f(0.75) = 1.125

d) the equation for the line of symmetry is x = 0.75
