The answer should be 0.40(1,125)=450
Firdavs [7]3 years ago
5 0

Step-by-step explanation:

0.40 = 40%

450 is the final.

Let's not talk about money for once.

40% of x is 450.

40% of the total cake is 450.

Answer:

Jake attended his friend Mark's birthday party. Mark only invited Jake. They had a red velvet cake to eat. Jake ate 450g of cake, which is 40% of the whole cake. How many grams was the original cake?

katovenus [111]
Hey there! :) The answer to your question is $12 per pound. To find a unit rate you divide $60/5= $12. To double-check, 1 pound is $12, 2 pounds is $24, 3 pounds is $36, 4 pounds is $48, and lastly 5 pounds is $60. I hope you have a great day, and keep smiling! :D Also hoped I helped! ;)

A number increased by 10 is 114 answer in an equation
enyata [817]
We have to make an equation: a number increased by 10 is 114.
An equation is:
x + 10 = 114
x = 114 - 10
x = 104.

Pls help me, i'm giving 30 points and brainliest.
podryga [215]

Answer:

This is a 10 percent increase

Step-by-step explanation:

Last week he spent 10 hours

This week 11 hours

percent increase = (new - original )/original * 100 percent

                             = (11-10)/10 * 100 percent

                             = 1/10 * 100 percent

                             = 10%

This is a 10 percent increase

Tensile-strength tests were carried out on two different grades of wire rod. Grade 1 has 10 observations yielding a sample mean
LuckyWell [14K]

Answer:

t = \frac{1085-1034}{\sqrt{\frac{52^2}{10} +\frac{61^2}{15}}} = 2.240

df = n_1 +n_2 -2 = 10+15-2= 23

p_v = 2*P(t_{23} >2.240) = 0.035

Since the p value is lower than the significance level we have enough evidence to conclude that the true means are different at 5% of significance

Step-by-step explanation:

Data given

\bar X_1 = 1085 sample mean for group 1

\bar X_2 = 1034 sample mean for group 2

n_1 = 10 sample size for group 1

n_2 = 15 sample size for group 2

s_1 = 52 sample deviation for group 1

s_2 = 61 sample deviation for group 2

Solution

We want to check if the two means are equal so then the system of hypothesis are:

Null hypothesis: \mu_1= \mu_2

Alternative hypothesis: \mu_1 \neq \mu_2

And the statistic is given by:

t = \frac{\bar X_1 -\bar X_2}{\sqrt{\frac{s^2_1}{n_1}+\frac{s^2_2}{n_2}}}

And replacing we got:

t = \frac{1085-1034}{\sqrt{\frac{52^2}{10} +\frac{61^2}{15}}} = 2.240

The degrees of freedom are given by:

df = n_1 +n_2 -2 = 10+15-2= 23

And the p value would be:

p_v = 2*P(t_{23} >2.240) = 0.035

Since the p value is lower than the significance level we have enough evidence to conclude that the true means are different at 5% of significance
