Answer:

$1.65

Step-by-step explanation:

You can get the cost of each banana by using the division operation. All you have to do is to divide $0.99 by 3.

Each banana costs $0.33

Now that you know the cost of each banana, you may now get the cost of 5 bananas by using the multiplication operation. All you have to do is to multiply $0.33 by 5.

Therefore, 5 bananas cost $1.65.

Answer:

(0.9036, 0.9064)

Step-by-step explanation:

Given that:

True mean (m) = 0.9050

Standard deviation (s) = 0.0100

Sample size ( n) = 48

Interval for 90% of the sample mean :

Mean ± Error

Error = Zcritical * (standard deviation /sqrt(n))

Zcritical at 90% confidence interval = 1.64

Hence,

Error = 1.64 * (0.0100/sqrt(48)) = 0.0014433

Lower boundary = m - Error = (0.9050 - 0.0014433) = 0.9035567

Upper boundary = m + Error = (0.9050 + 0.0014433) = 0.9064433

(0.9036, 0.9064)

Answer:

x = 12

y = 9

Step-by-step explanation:

[tex]\triangle ACD \cong \triangle BCD.. (given) \\\\

\therefore AC \cong BC\\\\

\therefore m(AC) = m(BC) \\\\

\therefore 2x = x + 12\\\\

\therefore 2x - x = 12\\\\

\therefore x = 12\\\\

Similarly \\\\

BD \cong AD\\\\

\therefore m(BD) = m(BD) \\\\

2y - 4= y + 5\\\\

2y - y = 4 +5\\\\

y = 9

The 95% confidence interval estimate of the proportion of people who say that they voted

(0.67122 , 0.72798)

Step-by-step explanation:

Step(i):-

In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.

Sample proportion

                          [tex]p = \frac{x}{n} = \frac{701}{1002} = 0.6996[/tex]  

Step(ii)

The 95% confidence interval estimate of the proportion of people who say that they voted

[tex](p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )[/tex]

[tex](0.6996 - 1.96\sqrt{\frac{0.6996(1-0.6996)}{1002} } , 0.6996 + 1.96 \sqrt{\frac{0.6996(1-0.6996)}{1002} } )[/tex]

(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)

(0.6996 - 0.02838 , 0.6996 + 0.02838)

(0.67122 , 0.72798)

Final answer:-

The 95% confidence interval estimate of the proportion of people who say that they voted

Answer:

The remainder is 6 !

Step-by-step explanation:

The remainder of the equation A = 46 / 8 is r = 6

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the remainder of the equation be denoted as = r

Let the dividend number be = 46

Let the divisor number be = 8

Now , the equation is represented as = A

The value of A is given by

A = 46 / 8

Now , the remainder will be

5 x 8 = 40

Substituting the values in the equation , we get

Dividend - 40 = 6

Therefore , the remainder of the equation A is 6

Hence , The remainder of the equation A = 46 / 8 is r = 6

Answer:

the percentage of adults have stage 2 high blood pressure is 0.0057

Step-by-step explanation:

The computation of the percentage of adults have stage 2 high blood pressure is shown below;

Given that

mean = 117

Standard deviation = 17

and, the sample is 160

Now based on the above information,

The percentage is

= (Sample - mean) ÷ (standard deviation)

= (160 - 117) ÷ (17)

= 2.529

p(z>2.53) = 0.0057

hence, the percentage of adults have stage 2 high blood pressure is 0.0057

Answer:

Step-by-step explanation:

[tex] \frac{2}{5} \times \frac{x}{59} [/tex]

the number of drops of nectar goes on the bottom, and the number of butterflies goes on the top

then you cross multiply to get 5x= 118

solve for × and you get 23.6

for this situation, 0.6 of a butterfly doesn't make sense, so we need to round down.

we round down because it's okay if there's extra nectar, but there can't be less than enough.

you can be 23 butterflies with 59 drops of nectar

Answer:

The rate of change is -4.5 and the relation of the table is a linear function

Step-by-step explanation:

Linear function.

A linear function can be identified because the rate of change is constant at every point of its domain.

The graph of a linear function is a straight line with a constant slope.

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We'll show the relation shown in the table is a linear function. We'll calculate the slope for any random pair of points. For example, using (2,83) and (3,78.5):

[tex]\displaystyle m=\frac{78.5-83}{3-2}=-4.5[/tex]

Now for (7,60.5) and (14,29):

[tex]\displaystyle m=\frac{29-60.5}{14-7}=\frac{-31.5}{7}=-4.5[/tex]

Proceeding in a similar way with any pair of points, the slope will always result in the same value, thus the rate of change is -4.5 and the relation of the table is a linear function.

Answer:

-2.23 ; 0.012874

Step-by-step explanation:

Given that :

Population mean (μ) = 25 minutes

Same mean (x) = 24min 12 seconds = 24.2 minutes

Standard deviation σ = 3

Sample size (n) = 70

Test statistic :

Using the relation :

Tstatistic = (x - m) / σ/sqrt(n)

Tstatistic = (24.2 - 25) / (3/sqrt(70)

Tstatistic = - 0.8 / 0.3585685

Tstatistic = - 2.2310939

= - 2.23

The P value can be obtained using a. P value Calculator :

P at α = 95% and test statistic = - 2.23

Hence, p = 0.012874 using calculator

======================================

Explanation:

For a conditional to be false, the antecedent must be true and the conclusion must be false. So the format is (true) --> (false) for the overall conditional to be false.

Since the antecedent must be true, this means p = true. We can shorten this to say p = T, where T stands for "true".

Now we must make (q v ~r) be false.

This is only possible if both pieces q and ~r are false. An "or" statement, aka disjunction, is true if either piece is true; otherwise it's false.

So q = F, where F stands for "false" and ~r = F as well.

If ~r = F, then r = T. Recall the squiggly line or tilde is basically the negation operator. It does the opposite of the statement.
