Answer:

Step-by-step explanation:

A) In ΔONE & ΔEST

ON // ST (Construction) and NS is transversal.

∠1 = ∠4 {alternate interior angles}

NE =ES {Given E is midpoint}

∠2 = ∠3 {Vertically opposite angle}

ΔONE ≅ ΔEST { A S A congruent}

OE ≅ TE {CPCT}

ON = ST {CPCT} ---------(I)

ON = OH -----------------(II)

From (I) & (II)

OH = ST & OH // ST (construction)

OHST is a parallelogram.

So, OE // HS -----------------(A)

OE = TE

OT = 2OE

OE = (1/2)OT

OE = (1/2)HS ------------------(B)

From A & B , midpoint theorem is proved

Find the angle, in radians, in the figure below if S = 8 and r = 6.

babymother [125]

Answer:

Value of theta Ф = 1.33 radians

Step-by-step explanation:

We are given :

S= 8

r = 6

We need to find angle Ф

The formula used is: S=rФ

Finding theta Ф by putting values in formula:

$S=r\theta\\\theta=\frac{S}{r}\\ \theta=\frac{8}{6}\\\theta=1.33$

So, value of theta Ф = 1.33 radians

Lynne feeds her cat 65 g of cat food per day. About how many ounces of cat food will she feed her cat in 5 weeks? 1 oz≈28.3 g

Svet_ta [14]

<span>Consumption in Grams would be 65 x 7 x 5 which 2,275 If we use the conversion rate of 28.3 grams to an ounce then the number of ounces will be found by completing this sum 2275 divided by 28.3 which is 80 Ounces when rounded down</span>

So confused need help. If u have a easy way to solve please help

ycow [4]

Answer: X= 6-4^z/2

Step-by-step explanation: first you need to get rid of the 4. You subtract it from both sides. So now

2x=6-4 to the power of z

So now you need to get rid of the 2. You divide both sides by two. Then you get

X= 6-4^z/2

The brand name of Mrs. Fields (cookies) has a 90% recognition rate. If Mrs. fields herself wants to verify that rate by beginnin

Schach [20]

Answer:

0.3874 = 38.74% probability that exactly 9 of the 10 consumers recognize her brand name.

0.6126 = 61.26% probability that the number who recognize her brand name is not nine.

Step-by-step explanation:

For each consumer, there are only two possible outcomes. Either they recognize the name, or they do not. The probability of a customer recognizing the name is independent of anu other customer. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The brand name of Mrs. Fields (cookies) has a 90% recognition rate.

This means that $p = 0.9$ .

Sample of 10

This means that $n = 10$

Find the probability that exactly 9 of the 10 consumers recognize her brand name.

This is P(X = 9). So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 9) = C_{10,9}.(0.9)^{9}.(0.1)^{1} = 0.3874$

0.3874 = 38.74% probability that exactly 9 of the 10 consumers recognize her brand name.

Also, find the probability that the number who recognize her brand name is not nine.

1(100%) subtracted by those who recognize. So

1 - 0.3874 = 0.6126

0.6126 = 61.26% probability that the number who recognize her brand name is not nine.
