The percentage shows that number of people that were surveyed is 866.

Let the number of people surveyed be x.

Therefore, from the question given and the percentage, the calculation goes thus:

82% × x = 710

0.82x = 710

x = 710/0.82

x = 866

The number of people surveyed is 866.

Answer:

f(x)=-4x-1

Step-by-step explanation:

f(x)=ax+b

a=-4/slope

b=-1/y-intercept

f(x)=-4x-1

By hit and trial of each option and also by graph, solutions to f(x) = 3ˣ and  g(x)=2x-1 will be 0 and 1.

given functions are,

[tex]f(x) = 3^x\\\\g(x) = 2x+1[/tex]

let us put x=0

f(0) = 1

g(0) = 1

f(0)=g(0)=1

so 0 will be a solution.

let us put x=1

f(1)= 3

g(1) = 3

f(1)=g(1)=3

so 1 will be also a solution

let us put x=2

f(2) = 9

g(2) = 5

f(2)≠g(2)

so 2 will not be solution.

x=-2 and x=-1 clearly will not be solution because,

g(-2) = negative value but f(x) cannot be negative, being an exponential function.

Any function in form f(x)= pˣ, where p≥1, is called an exponential function.

therefore, solutions to f(x) = g(x) will be 0 and 1.

The total amount of the initial deposit of Natalie account when she opened the account is $225.

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{Prt}{100}[/tex]

Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).

Natalie opened a bank account that earns 2. 5% simple interest.

Natalie's account earned $180 over the period of 10 years. The interest amount she earned is,

[tex]I=\dfrac{Prt}{100}\\I=\dfrac{180\times2.5\times10}{100}\\I=45[/tex]

The interest amount she earned is $45 and the initial amount was $180. Thus, the total amount,

[tex]A=P+I\\A=180+45\\A=225[/tex]

Thus, the total amount of the initial deposit of Natalie account when she opened the account is $225.

Answer:

The vertex form would be  y =  (x+2)^2

The factored form would be y = (x-2)(x-2)

The standard form would be y = x^2-4x+4

Step-by-step explanation:

To find this, you know that the vertex is 2 left from the center, so you have h = -2, and k = 0 since it isnt shifted up. The graph isn't shifted up either, so a=1.

The vertex form would be:  y = a(x-h)^2+k

                                                 =  (x+2)^2

The factored form would be y = (x-2)(x-2)

The standard form would be y = x^2-4x+4

60% of 25 = 15 and 2.52

Step-by-step explanation:

Answer:

60% of 25 should be 15.

for question 2: its 48

Step-by-step explanation:

1) 2.4 = 5% × Y

STEP 2: 2.4 = 5/100 x Y

Multiplying both sides by 100 and dividing both sides of the equation by 5 we will arrive at:

STEP 3 Y = 2.4 × 100/5

STEP 4) Y = 2.4 × 100 ÷ 5

STEP 5) Y = 48

Finally, we have found the value of Y which is 48 and that is our answer.

The weight would give a newborn a z-score of −0. 75 with mean 3500 g and standard deviation 500 g is 3125 grams.

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

A newborn who weighs 2,500 g or less has a low birth weight. use the information on he right to find the z score of a 2,500 g baby.

From the given parameters, the mean of the data is,

[tex]\mu=3500[/tex]

The standard deviation of the data is,

[tex]\sigma=500[/tex]

Thus, the z score can be given as,

[tex]z=\dfrac{x-\mu}{\sigma}\\-0.75=\dfrac{x-3500}{500}\\x=3125[/tex]

Hence, the weight would give a newborn a z-score of −0.75 with mean 3500 g and standard deviation 500 g is 3125 grams.
