Round 64.12 and 7.4 to whole numbers that divide nicely, and are CLOSE to the original numbers.

The normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution.

The usual normal distribution is then followed by the z variable. A value of the x variable's z variable, also known as the z-score of the x variable, indicates how many standard deviations from the mean it is.

The area under the normal distribution curve must be calculated that lies between

z=−1.56 and z=1.56

Using the standard normal table, the area is calculated as:

P(−1.56<z<1.56)

=P(z<1.56)−P(z<−1.56)

=P(z<1.56)−(1−P(z<1.56))

=0.9406−(1−0.9406)

=0.8812

The length and width of the rectangular poster are 23 inches and 7 inches respectively.

Here we have to find the dimensions of the length and width of the rectangular.

Data given:

length of the rectangular poster is 2 more than three times its width.

Let us assume that the width of the rectangular is x.

The area of the poster = is 161 inches²

So by this, we get the length 3x + 2.

width = x

length = 3x + 2

The formula of the area of the rectangular:

Area = length × width

161 = (3x+ 2) × x

161 = 3x² + 2x

3x² + 2x - 161 = 0

3x² + 23x - 21x - 161 = 0

x(3x + 23) - 7( 3x + 23) = 0

(3x + 23) ( x -7)= 0

x = -23/3, 7

As the length cannot be negative so we get the value of x as 7

width = 7 inches

length = 3x + 2

= 3×7 + 2

= 21 + 2

= 23inches

Therefore the length and width are 23 inches and 7 inches respectively.

if the null hypothesis is rejected in hypothesis testing the alternative hypothesis is true.

The relationship between important factors of interest and any apparent connection, according to a competing theory, is most certainly not accidental. The opposite of a null hypothesis is an alternative hypothesis. If we are able to rule out the null hypothesis, it signifies that we have enough data to support the alternative hypothesis. In one test, we cannot rule out both possibilities.

If one is disproven, it indicates that there is evidence to support the other. The opposing view is that a study's potential conclusion will materialize. It claims there is no coincidence in the relationship between important components of interest and the observed connection. As a result, the alternative hypothesis is true if the null hypothesis is disproved during hypothesis testing.

The probability of selecting D twice in the random selection is D. 4 / 9.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

It should be noted that the probability of selecting D will be:

= 2 / 3.

Therefore, the probability of selecting D twice will be the multiplication of the probability that's gotten twice. This will be illustrated thus:

= 2 / 3 × 2 / 3

= 4 / 9

Therefore, the probability is 4 / 9.

The ball will land 67.381 feet away.

Thus, option (B) is correct.

Given:

v = 62 feet / second

[tex]\theta[/tex] = 15

h = 2.2 feet

Using the formula

Horizontal range = [tex]\dfrac{v \;cos\; \theta\; [v \;sin\;\theta + \sqrt{v^2\;sin\;\theta + 2gh]}}{g}[/tex]

Substituting the value back into the formula as

Horizontal range = [tex]\dfrac{62 \;cos\; (15)\; [62 \;sin\;(15)+ \sqrt{(62\;sin\;(15))^2 + 2g*2.2]}}{g}[/tex]

the ratio of women to children on the tour is = 5 : 2

let the number of men in the sight seeing tour =  m

let the number of women in the sight seeing tour =  w

let the number of children in the sight seeing tour =  c

So , w/c = 5x/2x

also the ratio of children to men is 5/11 ,

c = 5y and m = 11y

the number of women on the sight seeing tour is less than 30 ,

which is 5x < 30 ,

x < 6

but we have c = 2x and 5y ,

and since c is a multiple of 5 , 2x also has to be a multiple of 5 ,

earlier we got , x < 6 ,

Now using x =5 , we get c = 2*5 = 10
