Answer:

From the given data, there is not enough evidence to prove that there is a statistically significant difference between the two population means

Step-by-step explanation:

The number of younger moms, in the study = 837

The average weight gain of younger moms, [tex]\overline x[/tex]₁ = 30.67 pounds

The standard deviation of the weight gain of younger moms, s₁ = 14.69 pounds

(30.67 - 28.52)/√((14.69^2)/837 + 13²/143))

The number of younger moms, in the study = 143

The average weight gain of mature moms, [tex]\overline x[/tex]₂ = 28.52 pounds

The standard deviation of the weight gain of mature moms, s₂ = 13 pounds

The test statistic for the difference in two populations is given as follows;

[tex]t=\dfrac{(\bar{x}_{1}-\bar{x}_{2})}{\sqrt{\dfrac{s_1^{2} }{n_{1}}-\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]

Therefore, we get;

[tex]t=\dfrac{(30.67-28.52)}{\sqrt{\dfrac{14.69^{2} }{837}-\dfrac{13^{2}}{143}}} \approx 1.7919[/tex]

The test statistic ≈ (1.7919)

Using a graphing calculator, we get;

The critical-t = ±1.971379, p = 0.07459697

Therefore, given that the test statistic, (1.7919), < critical-t (0.07459697), we fail to reject the null hypothesis, therefor, the given data does not provide convincing evidence that there is a significant difference between the two population means

Answer:

[tex] \boxed{ \tt{2.2 \: degrees}}[/tex]

Answer:

theyre vertical angles and x is 16

Step-by-step explanation:

7x+16=128

7x=128-16

7x=112

x=112/7

x=16

hope i helped! mark as brainliest pls <3

Answer:

Vertical x = 16

Step-by-step explanation:

(7x + 16) = 128

7x = 128 - 16     -------    7x = 112

x = 112 ÷ 7

x = 16

Step-by-step explanation:

1. Ratio(White to black) = 12 / [52 - 12]

Ratio(White to black) = 12 / [40]

Ratio(White to black) = 3 / 10 = 3:10

2. Ratio(Blue triangle to all) = 5 / [5+80]

Ratio(Blue triangle to all) = 5 / [85]

Ratio(Blue triangle to all) = 1 / 17 = 1:17

3. Ratio(Circle to all) = 76 / [22+76]

Ratio(Blue triangle to all) = 76 / [98]

Ratio(Blue triangle to all) = 38 / 49 = 38:49

4. Ratio(Yellow triangle to blue) = 18 / 14

Ratio(Yellow triangle to blue) = 9 / 7 = 9:7

5. Ratio(Yellow triangle to blue) = 42 / 6

Ratio(Yellow triangle to blue) = 7 / 1 = 7:1

6.Ratio(Boys to all) = 63 / [27 + 63]

Ratio(Boys to all) = 63 / 90

Ratio(Boys to all) = 7 / 9 = 7:9

Answer:

what is the question yaaar

Answer:

C is the right answer have a good day

Answer:

Hey mate....

Step-by-step explanation:

This is ur answer.....

first we need to find the angle that is above 63 degrees, it will be much easier to know the next one....

= (Supplementary angle) 180 - 63

= 117

Expression = 23x + 2

= 23 x ? + 2

= (Multiplication of 23)

= 23 x 5 + 2

= 117

SIMPLE!

Have a look on the pic given below....

Answer:

Step-by-step explanation:

so from the silly drawing,  you can see that the triangle is 4 feet off the ground, and that we want to find the Opp side from our angle of 15 °

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

use TOA to find the Opp side of the triangle .. which is labeled X

Tan(15) = X / 15

15* Tan(15) = X

4.019   =   X

so the bird is up 4 feet in the tree.. not very high up, plus the 4 feet that the apple is already off the ground, soo

the tree... to where the bird is, at least, is 8.019 feet..

did this make sense?  :/  

hope the drawing helped  :P

The original hexagon has the area of:

Answer:

(4/3)^98units.

Step-by-step explanation:

By hexagonal property in which cut off the triangles obtained be the joining of m.p of adjacent sides which left 3/4 of total area.

Answer:

$56

Step-by-step explanation:

Here's an easy way to figure out this and any percentage question. One per cent (1 dollar out of $100) of $800 would be $8. So, if the man received 7 per cent out of $800, then just multiply $8 times 7, which is 56...so $56!

Hope it helps

It’s in my notebook, so I can’t show

Answer:

area of the figure=

[tex] \frac{1}{2} \times (25 + 31) \times \times 11 \\ \frac{1}{2} \times 56 \times 11 \\ 28 \times 11 \\ 308[/tex]

[tex]12 \times 14 \\ 168[/tex]

[tex]308 + 168 \\ 476[/tex]

Answer:

2bricks

Step-by-step explanation:

volume of cuboid = length × breadth ×height

step 1 : calculate the first one

v= 15cm ×8cm× 5cm = 1200cm^3

step 2 calculate the 2nd one

v= 15cm ×10cm×8cm = 600cm^3

number of bricks

1200cm^3 × 1bricks/ 600cm^3 = 2 bricks

Answer:

c. x21 + x22 + x23 less or equal than 2800 y2

Step-by-step explanation:

The plant has a maximum capacity of 2800 then the sum of all these operations must be equal to or less than 2800. The site of the plant has capacity constraint which needs to be determine through equation. The total capacity for the plant 2 is only 2800 the operation has to be distributed with keeping in mind the capacity limit.

Answer: 3 Sets of the 4 post cards and 3 of the single post cart sets.

Step-by-step explanation:

You buy 3 of the 4 post card set becuase that is the most you can get of those to get under 15 post cards.

You would now have 12 postcards now you have to buy 3 of the single set to get to 15 cards

Answer:

Espero que eso te ayude :D

Answer:

I think its D, Correct me if I'm wrong!

Step-by-step explanation:

Answer:

Q.1 lx²+mx

=x(lx+m)

Q.2 x² - ax - bx + ab

= x(x - a) - b(x - a)

=(x - b)(x - a)

Q.3 6ab - b²+ 12ac - 2bc

= b(6a - b) - 2a(6a - b)

=(b - 2a)(6a - b)
