If you vertically compress the linear parent function, F(x) = x, by multiplying by 1/2 , what is the equation of the new functio

ElenaW [278]

Vertical compression of a function is moving the graph of the function towards the x axis.
It is done by multiplying F(x) with IaI<1, the absolute value of a is less than 1. Then we get f(x)=a*F(x).

If we have a function F(x)=x, and we multiply it by a=1/2, we get:

f(x)=a*F(x)=a*x=(1/2)*x.

This linear function is vertically compressed because the the graph of a new function is closer to the x axis.

when a probability is expressed as a fraction, what does the bottom number represents A. the number of possible out comes B. the

masya89 [10]

Answer:

A. the number of possible out comes

Step-by-step explanation:

Probability is the chance of an event/something to happen.

The formula is;

Probability = the number of ways of achieving success/Total number of outcomes

The numerator position will have a value to show the number of ways of achieving success while the denominator will show the number of outcomes

For example the number of possible outcomes when a coin is flipped is 2, a tail or a head. So the probability of getting a head is P(H)= 1/2 where 2 is the number of outcomes

vlada-n [284]

Answer:

The net speed per 24 hours is 5 - 4 = 1 foot.

1 ft / 24 hrs = 16 ft / x hrs

16 * 24 hrs = 16 days (384 hrs)

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probabili

ivolga24 [154]

Answer:

(a) The mean and the standard deviation for the numbers of peas with green pods in the groups of 36 is 27 and 2.6 respectively.

(b) The significantly low values are those which are less than or equal to 21.8. And on the other hand, the significantly higher values are those which are greater than or equal to 32.2.

(c) The result of 15 peas with green pods is a result that is significantly low value.

Step-by-step explanation:

We are given that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probability that a pea has green pods.

Assume that the offspring peas are randomly selected in groups of 36.

The above situation can be represented as a binomial distribution;

where, n = sample of offspring peas = 36

p = probability that a pea has green pods = 0.75

(a) The mean of the binomial distribution is given by the product of sample size (n) and the probability (p), that is;

Mean, $\mu$ = n $\times$ p

= 36 $\times$ 0.75 = 27 peas

So, the mean number of peas with green pods in the groups of 36 is 27.

Similarly, the standard deviation of the binomial distribution is given by the formula;

Standard deviation, $\sigma$ = $\sqrt{n \times p \times (1-p)}$

= $\sqrt{36 \times 0.75 \times (1-0.75)}$

= $\sqrt{6.75}$ = 2.6 peas

So, the standard deviation for the numbers of peas with green pods in the groups of 36 is 2.6.

(b) Now, the range rule of thumb states that the usual range of values lies within the 2 standard deviations of the mean, that means;

$\mu - 2 \sigma$ = 27 - (2 $\times$ 2.6)

= 27 - 5.2 = 21.8

$\mu + 2 \sigma$ = 27 + (2 $\times$ 2.6)

= 27 + 5.2 = 32.2

This means that the significantly low values are those which are less than or equal to 21.8.

And on the other hand, the significantly higher values are those which are greater than or equal to 32.2.

(c) The result of 15 peas with green pods is a result that is a significantly low value because the value of 15 is less than 21.8 which is represented as a significantly low value.

In triangle abc, AC=15 BC=11 and m

Oksana_A [137]

Answer: 10

Step-by-step explanation:

In a right angle triangle

Hypothenus ^2= opposite ^2+ adjacent ^2

According to a diagram below

Hypothenus =15

Opposite =?

Adjacent =11

Substitute for the values

15^2=11^2+opp^2

Opp^2=15^2-11^2

0pp^2= 225-121

Opp2=104

Opp= square root of 104

Opp= 10.2

Opp= ~10
