Estimate the product of 5 and 4 Then find the product.

Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.

How many four-digit whole numbers contain the digit pair "17" without other intervening digits? (Note that 2017 is one such exam

Elina [12.6K]

Answer:

There are 209 4-digit nu numbers with 17 as consecutive digits

Step-by-step explanation:

17xx xx represent 00 through 99, a set of {100} members.

y17z. y can be 1 through 9 {9}. z can be 0 thru 9 {10}

ww17 which includes 10 thru 99, a set of {90}

Add 100+90+10+9 to get 209 possible combinations.

Psychologist is measuring learning in mice. He assumes that a mouse learns to recognize a specific object after a random number

Sphinxa [80]

Answer:

Option B) 0.2143

Step-by-step explanation:

We are given the following in the question:

Numbers of exposures(x): 4,3,7

We have to find the maximum likelihood estimate of p.

Formula:

$\hat{p} = \dfrac{n}{\sum x_i}$

Putting the values, we get,

$\hat{p} = \dfrac{3}{3+4+7} = \dfrac{3}{14} = 0.2143$

Thus, the correct answer is

Option B) 0.2143

i'll give brainliest plss help!!!Paul earns money each week for mowing his lawn. He earns a flat rate lawn and earns an extra $1

guajiro [1.7K]

ANSWERS

(a) x represents the number of hours and y represents Paul's earnings.

(b) y - 24 = 1.50(x - 6)

(c) y = 1.50x + 15; b represents the flat rate

EXPLANATION

(a) In linear models, the x-variable is usually the independent variable, while the y-variable is the dependent variable. In this problem, we know that Paul's earnings depend on how many hours of additional yard work he does. Hence, the x-variable represents the number of hours Paul does extra yard work and the y-variable represents his earnings.

(b) A linear equation in point-slope form is,

$y-y_1=m(x-x_1)$

Where m is the slope and (x₁, y₁) is a point on the line.

In this case, we know that Paul earns an extra $1.50 per hour for additional yard work. If the additional yard work time in hours is represented by the x-variable, then the slope is 1.50.

Now, we need a point on the line. This is given in the problem, where it is said that when Paul worked 6 hours, he earned a total of $24. So the point is (6, 24),

$y-24=1.50(x-6)$

Hence, the equation in point-slope form is y - 24 = 1.50(x - 6).

(c) The slope-intercept form of the equation of a line is,

$y=mx+b$

We have to take the equation found in part (b) and rearrange it to find the equation in this form.

To do so, apply the distributive property to 1.50 on the right side of the equation,

$\begin{gathered} y-24=1.50x-1.50\cdot6 \\ \\ y-24=1.50x-9 \end{gathered}$

And add 24 to both sides,

$\begin{gathered} y-24+24=1.50x-9+24 \\ \\ y=1.50x+15 \end{gathered}$

The value of b is 15. Remember that b is the y-intercept, which is the value of the function when x = 0. This means that y = 15 when x = 0 and, therefore, 15 is the flat rate.

Hence, the equation in slope-intercept form is y = 1.50x + 15, and the y-intercept, b, represents the flat rate Paul earns without doing any extra work.
