Answer:

0.350

Step-by-step explanation:

Confidence interval = point estimate ± margin of error

Point estimate = Confidence interval - margin of error

To get the margin of error, we will take the average of the difference of the interval given. Given the confidence interval 0.325<p<0.375

Margin of error = 0.375-0.325/2

Margin of error = 0.050/2

Margin of error = 0.025

Using the interval of 0.375

Point estimate = 0.375 - 0.025

Point estimate = 0.350

Alonso went to the market with \$55$55dollar sign, 55 to buy eggs and sugar. He knows he needs a package of 121212 eggs that cos

Neko [114]

Answer: See explanation

Step-by-step explanation:

Based on the scenario in the question, the expression to calculate the number of boxes of sugar Alonso can buys will be:

= 2.75 + 11.50S ≤ 55

When solved further, this will be:

2.75 + 11.50S ≤ 55

11.50S ≤ 55 - 2.75

11.50S ≤ 52.25

S ≤ 52.25 / 11.50

S ≤ 4.54

He can buy 4 boxes of sugar

If x=3 what is 3x -5(9x3) divided by 2 and does any one wanna talk and at school?

mart [117]

<h3>Given :- </h3>

$\quad \qquad \bullet \quad \sf x = 3$

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

<h3>Solution :- </h3>

Let's Start :-

$\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}$

Putting the respective value of x we have ;

${ : \implies \quad \sf \dfrac{3\cdot 3- 5 (27 )}{2}}$

${ : \implies \quad \sf \dfrac{9- 135}{2}}$

${ : \implies \quad \sf - \dfrac{126}{2}}$

${ : \implies \quad \bf - 61}$

$\quad \qquad { \bigstar { \underline { \boxed { \pmb { \bf { \red { \underbrace { \therefore \dfrac{3x - 5 ( 9 \times 3 )}{2} = - 61}}}}}}}}{\bigstar}$

Which function is the inverse of f(x) =b^x

SCORPION-xisa [38]

Answer:

The correct answer is C.

Step-by-step explanation:

To find this, we need to note that in order to reverse the function of raising the b to the x power, we need to take the log base b of the function. Since the answer C is the only one containing that, it must be the correct answer,
