Answer: The probability that exactly 4 insects will survive = 0.2903.

Step-by-step explanation:

Given : The proportion of all insects in laboratory experiments killed by insecticide = 60%=0.60

Since , by using insecticide only two outcomes are possible either it kills or not kills , so we can use binomial.

Sample size of insects = 7

By using binomial probability formula : [tex]P(x)=^nC_xp^x(1-p)^{n-x}[/tex], where x is binomial variable , n = sample size and p is the probability of getting success.

Let x be the number of insects survived.

As per given , we have

n=7 , p=0.60

Now , the probability that exactly 4 insects will survive :

[tex]P(x=4)= ^7C_4(0.60)^4(1-0.60)^3\\\\=\dfrac{7!}{4!3!}(0.60)^4(0.40)^3\\\\= 35\times 0.1296\times 0.064 \\\\=0.290304\approx0.2903[/tex]

Hence, the probability that exactly 4 insects will survive = 0.2903

Given:

UT = 31.5

To find:

The measure of US.

Solution:

In the figure, WV bisects UT.

⇒ US = ST -------------- (1)

UT = US + ST

31.6 = US + US    (using (1))

31.6 = 2 US

Divide by 2 on both sides.

[tex]$\frac{31.6}{2} =\frac{2US}{2}[/tex]

[tex]15.8=US[/tex]

The measure of US is 15.8.

Answer:

C) 26 blocks

Step-by-step explanation:

For the firs one draw a dot where they start. Then draw a line going down and label it 10. Next draw a line going left and label it 24. Connect the end of those who lines to form a triangle. Now we can use the pythagorean theory.

a^2 + b^2 = c^2

a^2= side one (you choose)

b^2= side two (whichever side you didn't use out of the two)

c^2= the hypotenuse( this is the diagonal line you drew connecting the two lines at the end)

10^2 + 24^2 =c^2

100 + 576 =c^2

676=c^2     Since the C is still squared we have to squareroot both sides. This will cancel oout the ^2 on the C.

[tex]\sqrt{676} =\sqrt{c^2}[/tex]   Solve.

Salty spark is right

Step-by-step explanation:

for anyone who didnt know 0.25 is equivalent to 1/4 just to make it clear 1/4 IS the correct answer saltyspark just put it in decimal form.

To find Ilana's average speed, we divide the total laps by the total minutes, which results in one-fourth of a lap per minute.

To find the average speed, we divide the total distance by the total time taken

To determine Ilana's average speed, we need to divide the total distance (2 laps) by the total time (8 minutes). When we do that, we get 0.25 laps per minute.

This is also known as one-fourth of a lap per minute. That means, on average, Ilana completes a quarter of a lap every minute.

Step-by-step explanation:

No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet.  20 square required to make quilt.

Step-by-step explanation:

The given is,

                Area of an rectangular quilt - 80 square feet

               She made 16 squares

               Square have 2 feet long and 2 feet wide

Step:1

             Area of rectangular quilt = 80 square feet

             Area of 16 squares = 16 × Area of square..................(1)

            Formula for area of square,

                                       [tex]A = a^{2}[/tex]................................(2)

           Where, a - Sides of square

                        a = Length = Wide

           From given,

                        a = 2 feet

          Equation (2) becomes,

                                          [tex]A = 2^{2}[/tex]

                                          A = 4 square feet

         Equation (1) becomes,

                          Area of 16 squares = 16 × 4

                                                          = 64 square meters

         Area of rectangular quilt ≠ Area of 16 squares

                                    80 ≠ 64

         Area of square is less compare to area rectangular quilt, so we need more square,

       Required amount of square area = 80 - 64

                                                               = 16 square feet

               Required amount of squares = [tex]\frac{16}{4}[/tex]

                                                                = 4 squares

       Total(16+4) square areas = 20 × 4 = 80 square feet

          Area of rectangular quilt = Area of 20 squares

                         80 square feet = 80 square feet

Result:

         No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.

To find the sum of all the numbers you simply would do 8+7+9.

That is 24.

When finding mean you add up all your numbers then divide by the total number of number (I know that sounds a bit confusing. In this case there are only 3 numbers, so that is the one you will use for dividing)

With a total perimeter of 150 inches and a width of 42 inches, the length was calculated to be 33 inches, option D.

To determine how long the quilt is, we need to calculate the perimeter of the rectangular quilt and then solve for the missing length. Since Annita needs 150 inches of lace, we know this is the total perimeter (P) of the quilt. The quilt is 42 inches wide. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). We can set up the equation as 150 = 2(length) + 2(42).

Now let's solve for the length (L):

The length of the quilt is 33 inches, which corresponds to option D.

The length of the quilt is 33 inches.

The correct option is (D).

To find the length of the quilt, we need to use the formula for the perimeter of a rectangle, which is given by:

[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]

Given that the width of the quilt is 42 inches and Annita needs 150 inches of lace to go around the entire quilt, we can set up the equation as:

[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]

Now, let's solve for the length [tex](\( \text{Length} \)):[/tex]

[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]

[tex]\[ 75 = \text{Length} + 42 \][/tex]

Subtract 42 from both sides:

[tex]\[ 75 - 42 = \text{Length} \][/tex]

[tex]\[ \text{Length} = 33 \][/tex]

So, the length of the quilt is 33 inches. Therefore, the answer is option D. 33 inches.

Answer:

$882.24 compound interest earned / $1,082.24 total

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

[tex]P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Now lets plug in the values into the equation.

[tex]200(1+\frac{.325}{1} )^{6}[/tex] = 1,082.24

Since we want to know the compound interest earned, just subtract 200 from 1,082.24.

1,082.24 - 200 = $882.24
