Answer:

y=2 is the correct ans.

here, tge equn of st line passing through the point (3,2) and is also parallel to y axis.

we have, equn of st line parallel to y xaus is y= b

so , the equn of st line passing through the point (3,2) is y= 2 (where 2 is likely to b).

grandymaker [24]

Answer:

It can be used the confidence interval to check the idea.

The confidence interval tells us that the real mean is expected to be between 40.2 and 40.4, with a 95% of confidence.

We can conclude that the mean diameter has moved away from the target value.

Step-by-step explanation:

A method to determine wether the mean diameter has moved away from the target is to calculate a confidence interval over the mean.

This would let us know if the real mean diameter could be 40 mm or not.

If the confidence interval does not include the value 40 mm, we can claim that the mean diameter has moved from the target value.

We will calculate a 95% confidence interval (CI), for which the z-value is z=1.96.

The margin of error is:

$E=z*\sigma/\sqrt{n}=1.96*0.5/\sqrt{100}=0.098\approx 0.1$

Then, the upper and lower limits of the CI are:

$UL=\bar x+z*\sigma/\sqrt{n}=40.3+0.1=40.4\\\\\\ LL=\bar x-z*\sigma/\sqrt{n}=40.3-0.1=40.2$

The confidence interval tells us that the real mean is expected to be between 40.2 and 40.4, with a 95% of confidence.

We can conclude that the mean diameter has moved away from the target value.

jane and ben share a lottery win in the ratio 7:3, if Jane's share of the money is $5600, how much does ben recieve

DIA [1.3K]

Let the Total Amount of money won in Lottery be : L

Given - Jane and Ben share the Lottery in the Ratio 7 : 3

$\implies \mathsf{Jane\;share\;of\;money = \left(\dfrac{7}{7 + 3}\right) \times L}$

$\implies \mathsf{Jane\;share\;of\;money = \dfrac{7L}{10}}$

Given : Jane's share of money is $5600

$\mathsf{\implies \dfrac{7L}{10} = 5600}$

$\mathsf{\implies L = \dfrac{56000}{7}}$

$\mathsf{\implies L = 8000}$

$:\implies$ Total Lottery Money = $8000

$\implies \mathsf{Ben's\;Share = \left(\dfrac{3}{7 + 3}\right) \times 8000}$

$\implies \mathsf{Ben's\;Share = \left(\dfrac{3}{10}\right) \times 8000}$

$\implies \mathsf{Ben's\;Share = \left(3 \times 800\right)}$

$\implies \mathsf{Ben's\;Share = 2400}$

<u>Answer</u> : Ben received $2400

If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.

makvit [3.9K]

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

3x - 31 = 2(x+6)
3x - 31 = 2x + 12
3x - 2x = 12 +31
x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98

GrogVix [38]

Answer:

<h2>See the explanation.</h2>

Step-by-step explanation:

(a)

Total number of degree recipients are 3831.

From 3831 recipients, 1 can be chosen in $^{3831}C_1 = 3831$ ways.

Among the 3831 recipients, total number of male is 1574.

Similar as above, 1 male can be chosen in 1574 ways.

Hence, the probability of the chosen person being a male is $\frac{1574}{3831} = 0.4108587$ ≅ 0.4109.

(b)

Total males are 1574 in number.

Among them 326 males have done masters.

The probability of the chosen male has done masters is $\frac{326}{1574} = 0.2071156$ ≅ 0.2071.
