Speed of the jet = 460/2 miles/hour = 230 miles/hour.
In 9 hours, the jet can fly = 9×230 miles = 2070 miles.

$\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}$

<h2>GIVEN - </h2>

Water tank which is in a shape of right rectangular prism

Dimensions = 6 feet × 4 feet × 7 feet

Surface area of tank

<h2>SOLUTION - </h2>

Using formula of surface area of right rectangular prism -

Surface area =

$2(wl + hl + hw)$

L = length

w = width

h = height

( assumimg 6 feet = L , 4 feet = W , 7 feet = h)

Putting value of L, W and H in the equation. we get,

=2(4 × 6 + 7 × 6 + 7× 4)

= 2(24 + 42 + 28)

= 2( 94)

= 2 × 94

= 188

Answer:

293 feet per second

Step-by-step explanation:

1056000 feet per hour

1 hour = 60 minutes

1056000 divided by 60 = 17600 feet per minute

1 minute = 60 seconds

17600 divided by 60 = 293 feet per second

Researchers would like to test if the mean bone mineral density is different for the three different groups. Conduct an ANOVA te

laiz [17]

Answer:

H₀: μ₁ = μ₂= μ₃

Hₐ: At least one of the means is different.

Step-by-step explanation:

Analysis of variance or ANOVA test is used to determine whether the means of different groups are similar or not.

The hypothesis of an ANOVA test for n homogeneous groups is:

$H_{0}: \mu_{1}= \mu_{2}= \mu_{3}...= \mu_{n}\\H_{a}: At\ least\ one\ of\ the\ means\ is\ different$

In this case the researcher is testing whether the mean bone mineral density is different for the three different groups.

The hypothesis for this test can be defined as follows:

H₀: The mean bone mineral density is not different for the three different groups, i.e. μ₁ = μ₂= μ₃

Hₐ: The mean bone mineral density is different for the three different groups, i.e. at least one of the means is different.

5a) rotational symmetry is 2 because it can be rotated only 2 times before it turns to the original form.

b) perimeter is the total surface of all the sides so, because we are given a scale of 1 unit = 1cm then our measurements would be: 4cm + 3cm + 2cm + 1cm + 4cm + 3cm + 2cm + 1cm = 20cm.

c) To workout the area we need to divide the irregular shape into separate regular shapes. the diagram will help you! Shape 1 is a rectangle so, area = L × W = 3 × 2 = 6cm. Shape 2 is a square so, area = side² = 2² = 4cm. Shape 3 is the same as shape 1 so the area is 6cm. Now to find the area of the whole shape we add these values so, 6+4+6= area of shape = 16cm.

d) The diagram will show the answer!
