Simplify (8+(-3))(-5 3/5) Help!

Answer:

30 weeks

Step-by-step explanation:

$450÷$5=30

He already had $50 in there

Answer:

30 Weeks

Step-by-step explanation:

Since we need to reach a total of 500, we have 50, so we need 450 to get 500, 15 a week, 30 times 15 equals 450. So (30 Weeks) times (15 Each Week) equals 450 plus that 50 he added in the savings account.

Answer:

15 girls

Step-by-step explanation:

Well, the ratio of 2/3, boys to girls. So, you would then try to find an (almost) common denominator, so 2/3 is equivalent to 10/15. In this case, there would be 15 girls

Answer:

width= 223.9 ft

Step-by-step explanation:

perimeter=2(l+w)

948.2=2(250.2+w)

948.2=500.4+2w

948.2-500.4=2w

447.8=2w

w=447.8/2

  =223.9 ft

Answer:

The correct equation is actually: y=10x+10.

Jaiden calculated the slope of the line incorrectly, as the y-axis increases by 10, not 2. The correct slope of the line is 20/2, which is equal to 10.

Hope this helps!

Answer:

You would use the distributive property.

Step-by-step explanation:

2(x+4) = 2x+8

2x+8x = 2x+8

10x = 2x+8

10x - 2x = 2x-2x+8

8x = 8

8x/8 = 8/8

x = 1

Answer:

Plot a point at the y-intercept.

Step-by-step explanation:

You start by plotting the y-intercept because you'll already have the value when you substitute x as 0 in the expression.

y = 0.5(0) -4

y = -4

Answer:

Ivan got £90 more than Tanya.

Step-by-step explanation:

Ivan and Tanya share the amount £150 in the ratio of 4 : 1

Amount received by Ivan = [tex]150\times \frac{4}{(4+1)}[/tex]

                                          = [tex]150\times \frac{4}{5}[/tex]

                                          = £120

Similarly, amount received by Tanya = [tex]150\times \frac{1}{(4+1)}[/tex]

                                                             = £30

Difference in their amounts = 120 - 30

                                              = £90

Therefore, Ivan got £90 more than Tanya.                                                                                                        

Answer:

f(x) = Ca^x

x = years since 2000.

f(0) = 220000 = Ca^0 = C

f(x) = 220000a^x

f(1) = 220000(1-0.11) = 220000a^1

a = 0.89

f(x) = 220000(0.89)^x

So each year reduces by 89%

Answer:

9 m

Step-by-step explanation:

Given that:

Carousel diameter = 8m

Radius of carousel = 8m / 2 = 4m

From the attached picture :

xo = d ; from the diagram attached ;

Using Pythagoras :

Cosθ = Adjacent / hypotenus

Cos 60 = d / 4

0.5*4 = d

d = 2

d = 2m

d + length of Radius + initial distance from fence

2m + 4m + 3m = 9m

Answer:

£9095

Step-by-step explanation:

Given data

P=£8500

T= 3 years

R= 2.3%

The compound interest formula is

A= P(1+r)^t

substitute

A=8500(1+0.023)^3

A=8500(1.023)^3

A=8500*1.07

A=£9095

Hence the savings after 3 years is £9095

Answer:

110 feet

Step-by-step explanation:

The formula to find the area of a rectangular prism is A = 2 (wl + hl + hw)

Substitute the values:

A = 2 (5x5 + 3x5 + 3x5)

A = 2 (25 + 15 + 15)

A = 2 (25 + 15 + 15)

A = 2 (55)

A = 110

Answer:

np>10 and n(1-p)>10

Step-by-step explanation:

The Large Counts Condition for Normality: np ≥ 10 and nq ≥ 10.

The Large Counts Condition, also known as the Large Sample Size Condition, is a requirement that must be met to ensure that the sampling distribution of a sample proportion is approximately normal when sampling from a population. This condition is necessary to apply the normal distribution to the sample proportion for various statistical inferences.

Let's denote the following:

- n: The sample size, i.e., the number of observations in the sample.

- p: The population proportion of the characteristic of interest.

- q: The complementary probability to p, such that q = 1 - p.

The Large Counts Condition for Normality states:

np ≥ 10 and nq ≥ 10

In other words, the product of the sample size (n) and the population proportion (p) must be greater than or equal to 10, and the product of the sample size (n) and the complementary probability (q) must also be greater than or equal to 10.

When both of these conditions are satisfied, the sampling distribution of the sample proportion can be approximated by a normal distribution. This approximation is useful for constructing confidence intervals and performing hypothesis tests related to proportions.
